Visual & Operational Inspection
Before performing tests, perform a visual inspection of the following items:
- Inspect B/U LP fuse for an open. If fuse is open, check Orange wire for a short to ground between underhood electrical center and transaxle range switch.
- Inspect IGN 1 fuse for an open. If fuse is open, check Pink wire for a short to ground between instrument panel fuse block and Body Control Module (BCM).
- Inspect CTSY LAMP fuse for an open. If fuse is open, check Orange wire for a short to ground between instrument panel fuse block and Body Control Module (BCM).
- Inspect MALL/RADIO/DIC fuse for an open. If fuse is open, check Yellow wire for a short to ground between instrument panel fuse block and Body Control Module (BCM).
- Inspect PWR LOCK fuse for an open. If fuse is open, check Orange wire for a short to ground between instrument panel fuse block and Body Control Module (BCM).
- Inspect ground located on right side of instrument panel. Ground is attached to underside of cross bar beam to left of ventilation duct.
- Inspect ground located near bottom of right B pillar.
- Inspect ground located near bottom of left D pillar.
- Inspect door lock system for mechanical binding.
- If one actuator does not operate properly, but other actuators operate normally, inspect wiring to suspect actuator. If wiring is okay, check for a poor connection. If no poor connections are found, replace suspect actuator.
- Each door lock actuator contains an electronic circuit breaker. Resistance in door lock actuator will increase if door lock actuator is overloaded. Resistance will return to normal after voltage is removed from actuator terminals. Check for a broken or partially broken wire inside wire insulation which could cause a system malfunction but check good during a continuity or voltage check.
- If lock and unlock modes are not functioning properly, set the mode to desired customer operation and test its function. If mode is inoperative, go to SYMPTOM DIAGNOSIS under DIAGNOSIS & TESTING .
- If Content Theft Deterrent (CTD) system is active, doors cannot be unlocked. Disable CTD system by unlocking doors using door lock cylinder switch or Remote Keyless Entry (RKE) transmitter. Check if door locks operate normally.
- Always check terminal contact before replacing any component.
- Inspect for proper installation of aftermarket electronic equipment which may affect system operation.
