Subject:  Diagnostic information on “Parasitic Battery Draw” with possible “No Start” condition – BCM (Body Control Module) power timer. 

Models: 2006 – 07 Buick Lucerne

2006 – 07 Cadillac DTS

2006 – 07 Chevrolet Impala, Monte Carlo

2007 Cadillac Escalade, Escalade ESV, Escalade EXT, SRX

2007 Chevrolet Avalanche, Equinox, Tahoe, Silverado, Suburban

2007 GMC Sierra, Yukon, Yukon XL, Denali, Denali XL

2007 Pontiac Torrent 

Based on GM bulletin: 1868070

When performing a diagnosis on a battery that has gone dead overnight, an installer may notice that the vehicle has approximately 4.1 amp draw on the system. The draw may be steady or may drop to a few millivolts then go back up to 4.1 amps. 

This may happen if you install an overhead monitor or other accessory and connect to the orange constant positive power wire in the vehicle’s courtesy light circuit. This will cause the power timer in the BCM to keep re-starting. The BCM will awake and draw 4.1 amps. 

This orange wire circuit exits the BCM at pin 1 of connector 2. Cut the wire to test this condition.  

Feed your aftermarket accessory in a different fashion.

Prepare your future. It wasn't the lack of stones that killed the stone age.
