DTC Advanced Diagnostics: P030A, P030D, P031A, P031D, P035A, P035D: General Description
The ignition coils are controlled by the duty command from the powertrain control module (PCM) and the PCM provides energy to the ignition coil and ignites the spark plug. The output driver circuit in the PCM monitors the voltage level of the IGN terminal. If the abnormality of the terminal voltage level is detected, the PCM detects a malfunction and stores a DTC.
