Circuit/System Testing
IMPORTANT:
- Verify that DTC P0562 is not set as current or history.
- If DTC P0562 is set, refer to DTC P0562 (ECM) or DTC P0562 (FSCM) .
- Ignition OFF, disconnect the harness connector of the FPCM.
- Ignition ON, test for greater than 11 volts between the IGN voltage circuit terminal 15 and ground.
- If less than the specified voltage, test the IGN voltage circuit for a short to ground or an open/high resistance. If the circuit test normal and the ECM - IGN fuse 58 is open, test the voltage circuit for a short to ground. If the circuit tests normal, test or replace the Run/Crank relay.
- If all circuits test normal, replace the FPCM.
