Wiring Issue
After throwing a few parts at my '99 myself to try and solve ABS/TCS codes (C1276, C1285, C1288), a mechanic has determined that three wires have "pulled out" of the EBCM connector. Unfortunately, all three are light blue with no tracers. He is not interested in trying to trace them. What is the best (or only) method of trying to resolve this?
Thanks,
Chuck

I have to hold my head in shame. Cant believe that your post isnt even commented on yet!
So, heres what I recommend:
All three blue wires go somewhere. I will need to get to my home computer to pull up my service manuals to further advise you where the wires go. Im in Guam so you will receive the info at some really weird hour of the night!
Once you know where all the blue wires go, disconnect the connectors at those locations and using an ohm meter read one wire in the EBTCM connector and touch the other blue wires in each of the other connectors. When you read ZERO ohms, mark that wire as to where it goes.
The schematic for the EBTCM will tell me what wire goes to what pin with reference to the component that it goes to.
Send me your e-mail address and I will send you the schematic.

Lt Blue wires
EBCM has a total of 5 Lt Blue wires.
Pin 6--Stop Lamp Supply Voltage
Pin 11--Left Front Wheel Speed Sensor Signal
Pin 18--Steering Wheel Position Signal B
Pin 21--ABS/TCS Class 2 Serial Data
Pin 28--Steering Position Sensor Signal
Maybe this will help you get started untill Bill can get back to you, HE is the man.

For a 99, there are a possible 7 Lt Blue wires as follows:
Pin 4 - SWPS B
Pin 9 - Stoplamp switch input
Pin 10 - Class 2 Serial Data
Pin 17 - SWPS Pulse
Pin 19 - Brake pressure differential switch Input (if equipped with JL4, if not the wire is white)
Pin 23 - SWPS Signal
Pin 31 - LF Wheel Sensor (low)

Here are the wiring diagrams you will need to identify the wires:

Dude,,,your HOOKED UP with some great info. Just do an end to end on one wire at a time and you will be able to figure it out.
Thanks guys.
My slow *** connection in Guam would have made sending the documents time consuming.
MAKE SURE that you tape and secure the EBTCM wiring harness so this iss will not happen again. If you need any more assistance, all you need to do is ask.
