General Info about the Omega One-Touch Sunroof
Posted: Wed Aug 04, 2010 9:24 pm
Following a recent fix of my sunroof module, I was asked to put down what I did.
In reality, I just replaced my faulty control module, but I thought I would do a full run-down of all that I know about these pesky devices.
So Here Goes.
This post is not so much how to fix, or even how to install an Omega One-Touch sunroof assembly, but I will give a brief overview of each.
This post, just informs you of the stages that I went through to replace my faulty roof control unit.
So - a brief roof install.
Preparing the Electrics.
1) You will need to remove your current interior courtesy light assembly - Unplug your light connections.
It is a good idea to disconnect the battery before messing with the wires.
The wire colours for information are: -
Red = permanent live
Black = Ignition Live
Brown = Chassis Earth
Grey = Door pin control (earth via door pins).
2) Assuming that you are removing a manually cranked sunroof mechanism, you will need to undo the Screw, holding the crank lever to the drive mechanism.
3) Remove the sunroof trim strip from the rear edge of the sunroof mechanism trim. - The trim should now fall away.
Normally, if you are fitting the rocker switch type of electric sunroof, the motor and switch will bolt to the roof panel quite easily, however you will need to make up spacer bushes for the front mounting screws.
If you are fitting an Omega One-touch sunroof mechanism, then there is a large steel bracket that needs to be removed, along with the drive cog, that was located at the mounting point of the crank lever.
Now then there is a 6 pin connector that plugs into the control module, which has the following wires.
Red - Permanent live - requires a source capable of providing 10A
Black - Ignition live - Can be taken from the black where fitted in the courtesy light assembly, or any ignition live supply
Brown (x2 wires) - connect to any chassis point - metal mounting screws are suitable for this.
Blue/Red - Speed pulse wire - not always required, but if you wish to connect this, then it goes to one of the three square connectors in the driver's footwell, just below the main ECU.
Brown/White - Diagnostic / Tech 1 programming wire - again to connector in the drivers footwell.
Brown/Black - full closure wire. Will close the roof with ignition off when you short it to earth. This should be connected to the central door locking unit in the driver's footwell. This will close the roof, if you turn and hold the key in the drivers door lock to the 45 degree position (window closure position)
Whilst everything is off, it is a good idea to offer up the main trim panel, and look where the front fixture screws need to go - you will need to drill these holes, as they do not line up with the original "Omega" mounting holes.
