Trouble Shooting: Notes

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer system have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION Section before disconnecting battery.

Before proceeding with specific testing, check the following for proper operation:

Check courtesy light and 15-amp courtesy light fuse for proper operation.
Check power seat system operation. Ensure power accessory circuit breaker is okay.
Check and ensure grounds are clean and tight.
Manually operate door locks. Ensure lock rods and lock mechanism function are normal.
Examine sliding door contact switch for damage.
If power accessory circuit breaker opens when power door locks are operated, check for possible short to ground.
Check for broken or partially broken wire inside insulation, which could cause system malfunction, but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring voltage drop with system operational (under load).
Check for proper installation of aftermarket electronic equipment.

If the above items check out okay, proceed to following trouble shooting procedures:
