As many of you have run into the EBCM failure (DIC code C1214 - Sol Valve relay Contact or coil CKT Open) and the infamous Service Traction Control/Service Active Handling/Service ABS - and let's not leave out the "shame you into the service center" lights that won't go off the dash, I thought I'd take a minute to say I just replaced my EBCM.

I got the part from gmpartsdirect.com for nearly half what the stealership wants for it. And as far as putting it in - you could grab 2 or 3 kids off the short bus and let all of them take turns following your instructions and the slowest one would take about 30 minutes. It's a complete joke. I did mine from the topside and wouldn't even have had to get under the car except that I dropped a bolt and had to pick it up off the ground.

Put the part in, turned key to on position, watched the lights go off after a month of looking at them, checked for codes, system has joy - Did a quick test with competitive driving, perfect results - time for a beer.

EDIT: The instructions I used:



Removal Procedure

1. Turn the ignition switch to the OFF position.
2. Disconnect the EBCM harness connector.
3. Remove the two insulator nuts.
4. Lift the EBCM/BPMV out of the bracket high enough to
allow clearance to remove the insulator mounting bolt and
the EBCM.
5. Remove the insulator mounting bolt from the EBCM.
6. Remove the four EBCM to BPMV bolts.
7. Separate the EBCM from the BPMV by gently pulling apart
until
separated.
8. Carefully remove the seal.
The seal may by reused if it is not cut or damaged.

Installation Procedure

1. Clean the BPMV seal surface with alcohol using a clean
rag.
2. Install the seal to the BPMV if it is not cut or damaged.
3. Install the EBCM to the BPMV.
4. Tighten the four mounting bolts in the following equence:
- First pass to 27 inch Ibs.
- Second pass to 53 inch Ibs.

Important: If the insulator nut was removed it must be replaced with a new insulator nut.

5. Install the front EBCM insulator mounting bolt. Tighten
the bolt to 10 ft. Ibs.
6. Install the EBCM/BPMV into the bracket.
7. Install the two insulator nuts. Tighten the two insulator
nuts to 89 inch Ibs.
8. Connect the EBCM harness connector. Important: Both
sides of the EBCM harness connector must be engaged
with lever before closing.
9. Turn the ignition switch to the ON position; do NOT start
the engine.
10. Perform the Diagnostic System Check - ABS. (Don't let this scare you - this basically means let the car do what the car does, and show you that everything is OK with the system, and then investigate the DIC codes which should be cleared)
