Does anybody know what the signal should be from C362 at the LH door outstation and the BECM when operating the key switch?
Lines 1, 9 and 10 are my suspects

Also, does anything change when 'alarmed' or so?

I am still trying to sort out a lock mystery.

Those 3 wires are the serial link between the outstation and the BECM. They should show an average of around 5V on them at all times.

I don't believe they will change if the vehicle is in lockout - the outstation is somewhat of a 'dumb' terminal. It just takes physical inputs, and translates them to some form of serial signal which is sends to the BECM to control things - like locking, door open etc.

It then receives messages from the BECM to command outputs - such as the locking motors, window, mirror. It doesn't have anything to do with the deciding on lockout status etc - the BECM does this based on what it's seeing from the various inputs.

Hi Marty,
I have a feeling that this is it.. look at the 3 transistors.
In case somebody knows which type they are we'd all be grateful
