I was wondering if anyone may be able to lend some assistance. I am looking to make the sunroof close and perhaps open via alarm remote, using a Viper 1002, on a car without comfort close.
I have posted a wiring diagram below which is the original MFR's diagram.
Top is the BCM. As far as I can tell, the T6e/2 wire from the BCM acts as an accessory wire that turns off once a door is opened, and the wire provides a positive signal. To open the sunroof sliding the control switch provides 200 ohms, and fully tilted up 2600 ohms. The dotted line does not apply to my model as it does not have a CCU.
I suspect closing of the sunroof may be possible with a connection to the unused T6e/3 connector, although do not know if this would be positive or negative and whether it would be a long or short pulse. The wiring diagram simply describes this connector in relation to the CCU as "sliding sunroof adjustment control unit (actuation)". I guess once it starts involving relays, providing power to T6e/2, and ground to the T6f wires it starts to get a bit messy, so if this is the case would be happy with just a closure method.
E139 Adjustment controller
J245 Adjustment control unit (with motor)
T6f/1 5 volts
T6f/2 Earth
T6f/3 Potentiometer
T6f/5 Emergency close (does not work after door opened)
T6f/6 Earth
Thanks in advance.
