These models are equipped with a Body Control Module (BCM) that governs various systems such as the door locks, power windows, ignition lock and security system, interior lights, Daytime Running Lights system, horn, windshield wipers, heating/air conditioning system, and power mirrors. Troubleshooting and diagnosis of any malfunction with this system should be done by a dealership service department or qualified automotive repair facility. The power door lock system operates through switches, actuators, and the BCM, and can usually be diagnosed and repaired by checking wiring connections and actuators. The lock switches send a signal to the BCM, which then sends a signal to the door lock solenoids. If troubleshooting steps do not identify the issue, consult a dealer service department. Always check circuit protection first, followed by checking for voltage at the switches and testing switch continuity. If necessary, check the wiring between the switch and door lock solenoid, and if a solenoid is not receiving voltage, check for an open or short in the wire between the solenoid and relay. For power door lock system communication issues, consult a dealer or qualified shop with the proper scan tool to retrieve trouble codes from the BCM. The keyless entry system consists of a remote control transmitter that sends a coded infrared signal to a receiver, which operates the door lock system. Replace the battery in the transmitter when it doesn't operate the locks at a distance of ten feet, with the normal range being about 30 feet. To replace the battery, carefully separate the case halves using a coin, pry out the battery, and snap the case halves together. Programming replacement transmitters requires a specialized scan tool, so take the vehicle and transmitters to a dealer service department or qualified repair shop for programming.
