DTC P0356: IGNITION COIL F PRIMARY/SECONDARY CIRCUIT
| Description: | This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module PCM. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | DTC P035x only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set DTC P035x. DTC P030x does not set for a coil primary circuit malfunction. DTC P035x may set with or without DTC P030x; however DTC P035x sets first. When this DTC is set, the PCM enters failure mode effects management (FMEM) which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation; do not attempt to diagnose the injector with this DTC present. If a primary coil is damaged due to a harness short to ground the PCM will not be damaged. Do not replace the PCM without verifying the coil driver functionality. Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector. Check the coil driver circuit for open, short to voltage, or short to ground. |
