How Do You Troubleshoot and Diagnose Malfunctions in the Body Control Module (BCM),Door Lock and Associated Systems on GMC Terrain?

Among other things, these models have a Body Control Module (BCM) which controls stuff like 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. For this system if there is any malfunction the troubleshooting as well as diagnosis should be done by a dealership service department or qualified automotive repair facility. The power door lock system works through switches, actuators and the BCM and can usually be diagnosed and repaired by checking wiring connections and actuators. A signal from the lock switches is sent to the BCM which then sends a signal to the door lock solenoids. Dealer service department should be consulted if troubleshooting steps do not identify the issue. Always check circuit protection first, followed by checking for voltage at the switches and testing switch continuity. Check wiring between the switch and door lock solenoid if necessary; if a solenoid is not receiving voltage check for an open or short in 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. When it doesn't operate locks at 10 feet range but normal range shall be about 30 feet replace battery in transmitter. To replace battery carefully separate case halves using a coin pry out battery snap case halves together. Programming replacement transmitters requires a specialized scan tool so take vehicle and transmitters to dealer service department or qualified repair shop for programming.
