Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the S117 refuel request switch.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 1 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  3. Verify the scan tool Refuel System Request parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 2 for a short to voltage. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.
  4. Install a 2 A fused jumper wire between the signal circuit terminal 2 and the B+ circuit terminal 1. Verify the scan tool Refuel System Request parameter is Active.
    • If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.
  5. If all circuits test normal, test or replace the S117 refuel request switch.
