PCM Controlled Generator Diagnosis
Diagnosis
Use the following diagnostic table to diagnose the generator L circuit.
Use the following scan tool parameter when diagnosing the PCM controlled generator. Generator L Terminal - Range Inactive/Active
The generator L terminal indicates whether the PCM is allowing the generator to operate. The PCM can disable the generator under certain conditions in
order to ease starting. Active indicates that the PCM is allowing generator operation, while inactive indicates that the PCM is not allowing generator
operation.
Circuit Description
The generator communicates to the Powertrain Control Module (PCM) over one line, the L or Lamp circuit. The PCM uses the L circuit to monitor faults
in the charging system.
