Will you please help me?

Is this the one you are refering to? If yes, it is the BCM. Start by checking for trouble codes.
That would be the one.....just to verify, checking the codes for this computer, would I still use same scanner, and hook up below steering wheel, like always?
sry, never had to test this one before....
And actually, I'm pretty sure my scanner won't read those codes...is there another way? What do those specific wires feed to?
Normal code readers would not show BCM codes. These are B codes.
What you need is a proper scan tool with the capabilities and there is no other way to go about.
The wires control a host of things that are somewhat interlinked in functions.
Schematic shows what each connector is for. It should be J2 connector you are refering to.
That helps out a little, at least narrow some things down. what would actually make that clicking noise? It almost sounds like a turn signal, but faster, which the signals are not on. id there any more wiring charts you can send over? I'm interested where it says computer data lines.
Clicking noises are usually from relays and it could be a bad connections (sometimes bad soldered joints of circuit boards), a failing relay which is incorporated into the BCM or even a poor ground. Computer datalines refers to the lines that goes to the computer and such lines usually cannot be tested by conventional means.
What I mean about not being able to test is the voltages or output. Of course you can test the continuity.
Just to add to this one what color is the connector you unplugged and the noise stopped?Was it blue?If so that the J2 connector and I will get you a pin out of it.Sounds like a bad bcm though.
It is the blue connector....Just to add, the wires in the both doors have been cut, along with the wires for the fuel & trunk doors.....would this make an impact on the situation?
