Trouble Shooting

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

• Check courtesy light and CTSY (15-amp or 20-amp) fuse for proper operation.
• Check power seat system operation. Ensure power accessory circuit breaker is okay.
• Check and ensure grounds are clean and tight.
• 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 have high resistance 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.
