Visual & Operational Inspection

Before performing tests, perform a visual inspection of the following items:

• Inspect DR LKS fuse for an open (located in instrument panel fuse block). If fuse is open, check Orange wire for a short to ground between fuse block and Body Control Module (BCM).
• Inspect CTSY LP/PWR MIR fuse for an open (located in instrument panel fuse block). If fuse is open, check Orange wire for a short to ground between fuse block and BCM.
• Inspect T/SIG/BULP/BTSI fuse for an open (located in instrument panel fuse block). If fuse is open, check Pink wire for a short to ground between fuse block and Park/Neutral switch.
• Inspect ground connector located behind right kick panel trim plate.
• 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.
• Always check terminal contact before replacing any component.
• Inspect for proper installation of aftermarket electronic equipment which may affect system operation.
