This bulletin is being revised to update the models and model years. Please discard Corporate Bulletin Number 07-08-47-004C (Section 08 - Body
and Accessories).
The purpose of this bulletin is to inform dealers of an issue that could cause internal module damage to the Body Control Module (BCM).
The BCM may be damaged when the module is supplied with battery power and the ground path is removed. You must remove the negative battery
cable first before removing a BCM ground.
Issue 1
Below is a list of vehicles and the components that the BCM ground path passes through. The negative battery cable must be removed when
removing the components noted below.
- 2007 Cadillac Escalade (Left instrument panel junction block)
- 2007 Chevrolet Avalanche, Silverado, Suburban (Left instrument panel junction block)
- 2007 GMC Sierra, Yukon (Left instrument panel junction block)
- 2008-2010 HUMMER H2 (Instrument panel electrical center)
- 2008-2010 Saturn VUE (I/P splice pack)
Issue 2
It is important to note when removing a ring terminal ground, splice pack connector, or inline harness connector for all the vehicles listed in the
model section above, that it doesn't include a BCM ground path. You must remove the negative battery cable if you determine that it is a BCM
ground path.
As an example: If the BCM grounds become disconnected, internal damage to the BCM will occur. Other systems controlled by the BCM will also
be affected, such as an inoperative or intermittent condition in one or more of the following systems:
- Interior lighting will remain on or will not work
- Exterior lighting will remain on or will not work
- Remote keyless entry
- Door locks
- Power windows and mirrors
- Remote vehicle start
- Remote trunk release
