Circuit/System Testing

IMPORTANT: Do not turn the key to the crank position or engage the starter at any time during diagnosis.
  1. Ignition ON, verify the scan tool Engine Oil Pressure (EOP) Switch parameter is Low.
    • If not Low, replace the instrument panel cluster (IPC).
  2. Ignition OFF, disconnect the EOP switch.
  3. Ignition ON, verify the scan tool Engine Oil Pressure Switch parameter is OK.
    • If not OK, test the signal circuit of the EOP switch for a short to ground. If the circuit tests normal, replace the ECM.
