2002 Escalade AWD 6.0 JL4 - Service Stability System - BPMV Part Number Needed
What an adventure this problem has been. What started out as a simple front caliper replacement soon turned into corroded, leaking brake lines, then the dreaded Service Stability System message on the DIC. After picking up the truck from my mechanic because of the leaking brake lines, the EBCM was throwing a C0286 code (only when the temperature was below 40 degrees F). The new gray MPA switch was then replaced without helping. I was then told it could be either the EBCM (they told me doubtful) and it was more than likely the Brake Pressure Modulator Valve (BPMV). Because of the believed cost (I have read here and the Internet), I got a second opinion. I took it to a local Chevy dealer and they confirmed it is indeed the BPMV. I have a quote of $1400 from the original mechanic and $1800 from the Chevy dealer. I can get either to install my supplied part plus two hours of labor. Does someone know the exact part number for my BPMV? My 2002 is an AWD 6.0L with the JL4 brake system. I believe the BPMV is 88983913, but would love to confirm. If this is the part, I could save over $500 on a new one from GMPartsDirect. $721 + a couple hours of labor could get me installed for under $1000.
I am hopeful this information will be useful to others since it appears to be a common problem on these trucks.
