Battery draw, RAP power timer resetting keeping BCM awake
Shop: LUTTRELLS AUTO CENTER
Date: 10/16/2008
The vehicle has a draw/drain on battery. If narrowed down to Courtesy light relay or BCM inadvertent power relay inspect for aftermarket DVD player in rear headliner. If it has one, pull the dome lamp and most likely it will get its main power there. If the DVD player is tapped into the ORANGE wire you have most likely found the problem. The orange wire is the LAMP REQUEST lead to the BCM.
The BCM senses the DVD as a lamp being on. What this does is when the key is out and the door is shut, the interior lamps are shut off, and the inadvertent power relays will time out in about 20 minutes. If someone turns on a dome lamp or aftermarket stuff is incorrectly wired, the BCM sees power flowing on the lamp request wire and will keep inadvertent power powered until timed out for about 2 seconds then reset the timer hence a constant draw.
You can actually test for this at the BCM by monitoring the voltage at lamp request wire, When it does time out for that 2 seconds the wire should show ground at once, if the voltage does not go away at once then there is a capacitive power at use (usually aftermarket stuff) bleeding voltage slow enough that when the BCM still sees voltage on that lamp request wire it will re-energize the wire for another 20 minutes.

COMPRESSION

Compression of this engine needs to be 400 lbs min.have found that some wear limit specs can be as low as 275lbs, which is incorrect low compression causes no power, excessive grey smoke, extended crank hot and very hard to start cold a vehicle here was at 350 lbs and all these symptoms were caused by it.
