DTC DESCRIPTION P0354 - IGNITION COIL D PRIMARY CONTROL CIRCUIT/OPEN
| 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: | The DTC P0354 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set the DTC P0354. The DTC P0304 does not set for a coil primary circuit malfunction. The DTC P0354 may set with or without the DTC P0304, however the DTC P0354 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 VPWR voltage at the ignition coil harness connector. Check the coil driver circuit for open, short to voltage, or short to ground. |
