Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
    IMPORTANT: You must perform the Circuit/System Verification first.
  1. Disconnect the reverse lockout solenoid harness connector.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal B and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the circuit fuse is open, replace the reverse lockout solenoid.
  3. Verify that a test lamp does not illuminate between the B+ circuit terminal B and the control circuit terminal A.
    • If the test lamp illuminates, test the control circuit for a short to ground. If the circuit tests normal, replace the ECM.
  4. Remove the test lamp.
  5. Command the reverse lockout solenoid ON with a scan tool. Verify with a scan tool that the reverse lockout solenoid Ckt. Short Volts Test Status parameter is OK.
    • If not the specified value, test the control circuit for a short to voltage. If the circuit tests normal, replace the ECM.
  6. Install a 3A fused jumper wire between the reverse lockout control circuit terminal A and the B+ circuit terminal B. Command the reverse lockout solenoid ON with a scan tool. Verify with a scan tool that the affected reverse lockout solenoid Ckt. Short Volts Test Status parameter is displaying Fault.
    • If not the specified value, test the control circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
  7. If all the circuits test normal, test or replace the reverse lockout assembly.
