VECTRA-B REMOTE CENTRAL LOCKING - HOW2 DISCUSSION.


I have resurrected this thread to allow discussion of the Vectra-B remote central locking How 2.

Link is on the second post.

I have added some information below to clarify the details mentioned in the original topic.

Additional information / observations.

If you have a Haynes manual for the Cavalier, it looks like it would be possible to connect the wires of the second Megamos CDL module connector to the alarm connector up behind the Cavalier glove box.

It is quite a few wires, but nothing too difficult to do.
It would also be quite a long link loom, travelling from the driver's footwell, across the car to the opposite inner wing up by the glove box. Probably a good 3 metre run, if going across the floor pan.

UPDATE - ON PAGE 3, I ADDED THESE LINKS TO THE STANDALONE HOW 2s FOR THE DIFFERENT SET UPS.

LINKS AS FOLLOWS.

Just to clarify this How 2.

viewtopic.php?f=70&t=6117

If you have the Kiekert Unit, it is little more than an early model remote central locking unit.
For this function in the Cavalier it is just plug and play.

If you have the Megamos Unit, this appears to superceed the Kiekert unit and is better suited for Central locking with Anti-theft warning system.
Hence the extra wires.

I have found that wired "as is" the Kiekert unit will not provide full closure function.

The Megamos unit, by virtue of being an upgrade on the Kiekert set up, should provide dead-lock and full closure if wired as described, AND if you fit a passenger door locking motor to the driver's door.
(Dead locking will not work via the remote fob with the Cavalier driver's door locking motor fitted.)

The additional challenge in either case, is getting the larger Vectra-B units to fit in the footwell, because the mounting hole centres are farther apart.
The plastic bracket that holds the three square ECU body loom connectors, will no longer fit.
At the minimum, it will need one leg cutting off the mount.

The cheats way may be to use sticky backed Velcro to locate the central locking unit and the connector support bracket, to reduce movement and vibration.

ALSO -
I have compared Dan's written pin out for the second plug against the Haynes manual.

Where he quotes:-
Pin 20 - Brown / Green - Bonnet switch contact.
Haynes reports this to be on pin 28.

Pin 22 - Brown / White.
Passenger Compartment Switch. This is the output to the dash switch to turn off the ultrasonic sensors.

Pin 25 - Brown / Violet.
Passenger Compartment Switch.
This is the output to the Alarm Status LED.
This will flash the led on the switch when the alarm is on, and during the setting process.

All other pins and explanations are correct.

TIS2000 has a slightly different opinion, so check the wire colours on your module.
The central door locking and power sounder have slight differences.

Based upon Haynes' Manual for Vectra-B (number 3396),
Wiring diagrams from TIS2000 and Dan's written note...

The following listings were obtained...

The 12 Pin Plug with big pins (same as Cavalier plug)

1 - Brown / Red - Power Sounder Return (only with Anti theft Warning System). ***
2 - Brown / Red - Input from door lock switch.
3 - Red - Ignition Live / Key In Voltage.
4 - Brown / White - Boot / Hatch lock switch.
5 - no connection.
6 - Brown / White - Input from door lock switch.
7 - Black / Yellow - Output to door motors.
8 - Black / Red - Output to door motors.
9 - Red - Permanent / Battery Live.
10 - no connection
11 - Brown - Ground / Chassis.
12 - no connection.

28 Pin Plug with small pins

1 - Red / Blue - Door lock key switch
2 - Red / White - Door lock key switch.
3 - no connection
4 - no connection
5 - no connection
6 - Black / Violet - Both Ultrasonic Sensors
7 - Brown - Both Ultrasonic Sensors
8 - Red / White - Left Ultrasonic Sensor
9 - White - Right Ultrasonic Sensor
10 - Black / Blue - Door Dead Locks ***
11 - no connection / output to interior light***

12 - Red / Blue - Left Ultrasonic Sensor
13 - Blue - Right Ultrasonic Sensor.
14 - Black / White - Multi-timer/ Output to turn signals ***
15 - Grey / White - Delay Interior light / Input from driver's door switch ***

16 - Grey - Door Pin / Dip switches
17 - Brown / White - Boot / Hatch light switch.(between bulb and switch).
18 - Red - Battery Live and Feed to Sounder
19 - Black / Blue - Doors Dead Lock ***
Or
19 - Brown / Red - Power Sounder Return ***

20 - Brown / Green - Bonnet Switch ***
21 - Brown / White - Diagnostic Socket (3)
22 - Brown / White - Dash Ultrasonic disable switch.
23 - Brown / Violet - Immobiliser
24 - Brown / Black - Roof / Window Closer
25 - Brown / Violet - Alarm switch status LED.
26 - Black - Pane Breakage sensors.
27 - no connection
28 - Brown / Green - Bonnet Switch ***


Items in bold and marked *** are where there are differences of opinion between Haynes', TIS2000 or Dan's notes.

An ideal solution would be to get a Kiekert unit to keep it simple,

Or if getting a Megamos, then ensure you get both connectors and some wiring with the module.
Saves head scratching, trying to work out which wiring format you have.

Looks like I might be looking into fitting Vectra-B remote central locking to my car.

New parts alert!!

Image

I have got a key blank and a new original GM button panel.

So - In a similar manner to doing the cruise control How 2, I will be able to do proper investigations into what a Kiekert central locking module can do...

Bear with me for a few weeks whilst I slot it in amongst all my other dis-jointed activities. :P

The front casing is a Vectra-B part.

The key blank is a Vectra-C part.
There are two sorts.. HU100 and HU43.
According to my purchase, the HU43 has the same "105" stamped on the shank, and looks the same shaped profile as my H1001 to H2000 Cavalier key.

I am also looking forward to doing this retrofit.
But, I have a dumb question. Umm, what associates the keyfob to the remote locking ECU? Or should the used remote central locking ECU come with its fobs? I am surprised as you have new parts.

The module should be paired to the remote key.
I have an old key which is linked to my central locking module.
But the casing is very worn due to repeated pressing of the buttons.

I have got a new key blank so that I can have it cut to suit my Cavalier locks.

And a new switch cover.

But I will be using the internals from the original key.

Note -
Unless you have an immobiliser type engine ECU, you will not need the transponder chip.
If you do have an immobiliser, you need to transfer your transponder chip into the remote key casing.

Also bear in mind, that the transponder chip does not affect the remote key's central locking function - and vice versa. They are separate entities.

and just so you know I am waiting for your investigation of the Kiekert module. It seems so simple than the other one I though didn't want to buy one as the other original how to mentioned that there is some function that doesn't work.

Re: Vectra-B Remote Central Locking - Discussion

I am currently looking for a front passenger side door solenoid motor, for the Cavalier. Part number is 90 277 866, I believe.

Loads for Corsa-B and Astra-F, but these do not appear to be the same part number.

Being my luck, they would probably not fit either the lock mounting or the electrical connector.

GPS do one for £90, but I am not 'that' desperate.

Nothing stopping me from getting the central locking module fitted, and getting the remote key cut and built up.

So - I believe the challenge at this stage is -
1 - Fit the Vectra-B Kiekert central locking module

2 - Obtain and fit a passenger door solenoid to the driver's door, to resolve the dead-lock micro-switch deletion issue.

3 - Get the key blank cut and build up remote key assembly.

4 - Add additional wiring for-
a - Dead-lock signal.
b - Possible dash alarm switch tell-tale LED
c - If necessary, full closure wiring.

At this point, I only expect 'a' to be achievable.
But that is the fun of the experiment.

I am not sure which bit that you say does not work, unless you mean in a previous thread rather than the How2.

I know that I was unable to sort out the dead-lock and full closure wires on an earlier occasion.
I partially blamed my badly fitted Meta alarm for interfering with the car's wiring.
It is probably more likely that I had missed an obvious clue.

We already know that dead-lock will not work unless a passenger door solenoid motor is fitted to the driver's door.

Gaz and Dan do not state whether they tried both Megamos and Kiekert units to test all functions.
Although Gaz does say that "both work just as well".

Wiring wise, I also see that Gaz mentions...

"You are left with two wires to connect.
1 - The black/blue to the car loom to make the dead-locking work on the fob rather than on the key.

2 - Join the brown/ black to the car to make the full closure work - purely optional but i would while you are there

The rest of the wires can be removed from the plug or just taped up - your choice."


This is where the fun begins, because I am sure that there are three considerations.

1 - There is no pin 5 wired in the Vectra-B module, but this pin is essential on the Cavalier module for the full closure.
(Haynes has the initials for powered sunroof on this wire - "FH").

2 - I seem to think that the black/blue may only be this colour within the door looms.
But red/yellow (or yellow/red) within the body loom. -Correction it all depends on which model and model year of car you have.

3 - Not sure, but I think there is some possibility that brown/black for full closure may be brown/red in some vehicles.
Again see comment 1 about pin 5.

All just to add to the confusion.

So to simplify - the most wires needed.

CAVALIER 12 PIN PLUG.

1 - Brown / Red - Input from Tailgate / Boot Lock (key switch) lock signal

2 - Brown / Red - Input from door lock switches. - Lock signal.

3 - Red - Ignition Live from fuse 12.

4 - Brown / White - Input from Tailgate / Boot Lock (key switch). - Unlock Signal.

5 - Brown / Red - To window lifter / sunroof - Comfort closure signal from door switch.
This will need the wire from small plug pin 24 connecting to the Cavalier body loom wire on pin 5.

6 - Brown / White - Input from door lock switches. - Unlock Signal.

7 - Black / Yellow - Output to door lock motors. "+" closed / "-" open.

8 - Black / Red - Output to door lock motors. "-" closed / "+" open.

9 - Red - Permanent Live from fuse 17.

10 - no connection

11 - Brown - Ground / Chassis.

12 - Black / Blue- Dead lock signal.
This will need the wire from small plug pin 10 connecting to the Cavalier body loom wire on pin 12.

VECTRA-B SMALL PLUG WITH 28 PINS.

10 - Black / Blue - Door Dead Locks
switch.
Connected to Cavalier yellow 25 pin alarm connector.

21 - Brown / White - 16 pin EOBD Diagnostic Socket pin 3.

24 - Brown / Black - Roof / Window Closer.
Connected to Cavalier yellow 25 pin alarm connector.

25 - Brown / Violet - Alarm switch status LED.
12 volt LED wired so that -
The positive leg (Anode) goes to pin 25 of the central locking module.
And negative leg (Cathode) goes to earth / ground / chassis.

Pin 25 will most likely NOT work on the Kiekert unit, but should work with the Megamos unit, normally as part of the anti-theft warning system.

I did post up a pin-out for the earlier Astra-G / Zafira-A, but removed it again when I realised that the pin numbers were confused.

Here it is again, but with my corrections. (Just the two red live feed pins are labelled wrong).

Image

Component numbers.
1 - Battery.
2 - Ignition Switch
3 - Engine Fuse Box
6 - Dash Fuse Box.
8 - Diagnostic Socket

132 - Right Hand Rear Door Lock Motor
133 - Tailgate Lock Motor
134 - Fuel Filler Flap Lock Motor
135 - Sunroof Motor
136 - Sunroof Switch

Corrected Pin Numbers in the order shown in the diagram.

1/3 ** Red - pin 3 of 12 pin plug (should be 2/3)
1/9 ** Red - pin 9 of 12 pin plug (should be 2/9)

2/6 Brown / white - pin 6 of 12 pin plug
2/2 Brown / red - pin 2 of 12 pin plug

Re: Vectra-B Remote Central Locking - Discussion

Post by Robsey »

I did a quick test of the remote central locking today.

The 28 pin plug has three wires.
Pin 10 - Deadlock.
Pin 21 - Diagnostics
Pin 24 - Full Closure

I "shoved" the wires into the 12 pin socket at locations 5 and 12 as mentioned a few posts ago.

The result - Nothing, big fat zero, zilch.

Well the driver's door, fuel flap and hatch all locked and unlocked as they should.
(See my WIP page 82 for more detail about my other doors).

Now I am sure the dead-lock situation may improve when I fit passenger door motors in both front door lock assemblies.

----------------------------------------

The full closure got me thinking.

On the cavalier, the key in the driver's door lock at the 45° position sets pin 5 of the central locking module to ground.

And I know that the sun-roof will close, if I set it's brown / black wire to ground with the ignition off.

So I am wondering what the output is from the Vectra-B central locking module pin 24 is?
The schematics in Haynes and TIS do not say.
If it is +12 volts, then it would not work wired directly to the cavalier pin 5.
The output to pin 5 needs to be to ground.

However, if output is +12 volts, then this could be used to drive a relay, that when triggered, would set the full closure wire on pin 5 to ground.

More testing to be done.

Reading the technical bumph in TIS says..

"Central closing of electronically controlled window winders and electrically actuated sunroof (both optional equipment) - Function cannot be performed via radio remote control"
:(

Although it does allow dead-locking
"Activating / deactivating the anti-theft device (ATD) in all doors".
:)

However on the pin out for the 28 pin plug, it details pin 24 as -
"Output 'central closing' for electronically controlled window winders and electrically actuated sunroof".
:scratch

Make your mind up guys, can it, or can't it do full closure?
:?:
Maybe only via the key in the lock.

And information for the Omega-B upon which the Vectra-B set-up is based, is non-existent.
:roll:

I love Vauxhall - ha ha.

UPDATE -
I have sussed this out.
If you have central locking only module, then dead-locking is not possible via remote signal.
See "further update" below.

If you have a central locking module WITH built in anti-theft function, then it is possible to dead-lock on the second press of the remote button.

FURTHER UPDATE -
Assuming you are connecting / fitting to a cavalier, then the wires in the 28 pin plug should be connected to the relevant pins in the 25 pin Cavalier alarm connector behind the glove-box.
This should work for Kiekert unit too.

Well it all confuses the poop out of me.

I ran a 12 volt led between each trigger wire and ground (the screw that hold the driver's door dip-switch), to see if either the full closure or dead-lock wires issued a 12v pulse when triggered via the key fob.

If a pulse was emitted, then the led should flash.

Alas, nothing...not on either wire.
Which is what I was expecting.
Most closure circuits trigger by shorting to earth.

I then set the led between a live wire (pin 3 of the 12 pin plug) and the relevant wires to see if a ground pulse was issued

The dead-lock wire appeared to be shorted to ground no matter whether the wire was triggered or not. The led remained lit, until I disconnected it.

And the full closure wire did nothing.
The led did not flash or anything.

Bugger!!

--------------------------

As a test of the Vectra-B module compared to the Cavalier module -
The driver's door works perfectly fine for normal remote locking and unlocking via the fob.
The full closure works from turning the key to 45° in the lock barrel.

So despite documentation identifying significant differences, the actual functions appear the same, although I did not test the boot / hatch lock switch function.

As such, there should be no wires in the Vectra-B set up to receive signals from the boot / hatch lock switch.

The electrical tests were a bit of a let down, as I was already thinking of a stage 2 for the project using these. :ugeek:

Image

Although there is no point starting stage 2 until the module itself is fully tested.
Or - until I can get a signal from pins 10 and 24. :scratch

I then looked at the Megamos wiring in Gaz's How 2.

Hmm permanent live on pin 18 of the 28 pin plug (??).
Although all diagrams for central locking without anti-theft warning do not show a red wire at all in the 28 pin plug.

Time to raid my wheelie bin full of wiring off-cuts, however I haven't found any of the correct shaped, tiny signal connector pins yet.
Only the later style female pins :roll:
I managed to find a fat red wire and connector for pin 18 :)

A clearer view of the Pin Outs according to TIS.

12 Pin Connector

Image

28 Pin Connector

Image

As you can see - no mention of pin 18 for battery live feed - Used by the anti-theft warning system to provide power to the sounders.
UPDATE - and I just noticed a new pin...
Pin 11 is now reported to send a signal out to the interior light.

But it is worth joining pin 18 to pin 9 of the Cavalier connector.?
A quick job to test the theory on Sunday perhaps.

I tried the central locking module again, but this time with the added red wire on pin 18 connected to pin 9 of the Cavalier plug.

The outcome = no difference compared to when the red wire was not fitted to pin 18.

------------------------------------------

I also shorted Cavalier plug pin 12 to earth.

Despite the micro-switch still being in the Cavalier door, it was not possible to unlock the drivers door with the door plunger.

More tests in due course, but at the moment, I cannot work out why pins 10 and 24 do not work in the 28 pin plug. :scratch

All can do full closure. If it was a control module of a Vectra then only via key, from Omega via key or remote. But the Vectra control module can be reprogrammed to Omega via Tech 2 and then it will also do both.

Ah - ok Tobias.
I tried this today.
I am assuming that you are referring to the Megamos unit, which is programmed via the Immobiliser.
Or
When the central locking unit is still fitted to a Vectra-B.

I have the Kiekert unit, which is programmed via Central Door Locking.

I have looked in both Vectra-B and Omega-B, but there is no option to change the Code Indexing to convert from Vectra-B to Omega-B.

Only options are to delete keys and program keys.

This was intetesting today, as it kept swapping between key 1 and key 5, when I pressed the lock and unlock buttons.

After reprogramming (synchronising) the key, it reported only key 1.
Here are images of my attempts today.

Image

I did have a check around, and got the following information.

Fault codes, as the module was tested on my kitchen work top.

Image

Measuring Blocks to test locking and unlocking.

Locking - strange how this says lock and dead-lock.
Image

Unlocking.
Image

But no way to make changes...

I then connected up my AutoScanner, and got the Hex Dump / Bin file for the Central Door Locking Eeprom.

Now if I could get my VauxCom 110530 Advanced to work, I would be able to pull any useful data from the hex tables.

(Apologies to those who think that this is rocket science or voodoo.).

The tests go on...as soon as I can find some suitable connector pins.

Update - I did get VauxCom 110530 advanced to work after installing NET framework 3.5.
But VauxCom only supports Engine and Infotainment ECUs on the Vectra-C and Zafira-B and Astra-H. :(
Nothing for pre-CAN cars.
