Powertrain Control Module (PCM)

During system operation, PCM transmits electrical reference signals to engine sensors and analyzes return signals to determine engine operating conditions. If a sensor, circuit or actuator fails, PCM initiates an alternate strategy, allowing vehicle to continue to be driven. PCM is located in left rear of engine compartment on firewall.

WARNING: Injector Driver Module (IDM) supplies 115-volts DC to all fuel injectors. DO NOT pierce injector wiring harness, severe electrical shock may occur.
