Visual & Operational Inspection
Before performing tests, perform a visual inspection of the following items:
- Inspect all fuses for an open. If fuse is open, check wiring for a short to ground.
- Inspect fuse No. 32 for an open. If fuse is open, check Orange wire for a short to ground between fuse block and door lock actuators.
- Inspect ground splice connector located behind instrument panel on right side of brake pedal bracket.
- 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 connections are okay, 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.
- Always check terminal contact before replacing any component.
- Inspect for proper installation of aftermarket electronic equipment which may affect system operation.
