SYSTEM OPERATION
The speed control electronic control circuitry is integrated into the Powertrain Control Module (PCM). The PCM is located in the engine compartment. The PCM speed control functions are monitored by the On-Board Diagnostics (OBD). All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for any failure it detects. See Starting and Charging/Charging System/Testing and Inspection/Procedures/On-Board Diagnostic Tests. The PCM cannot be repaired and must be replaced if faulty.
