Circuit/System Testing

  1. Ignition OFF, disconnect the KR95B rear compartment lid unlatch relay.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 86 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 B+ circuit fuse is open, test the control circuit terminal 87 for a short to ground. If the circuit tests normal, test or replace the KR95B rear compartment lid unlatch relay.
  3. Connect a test lamp between the control circuit terminal 85 and the B+ circuit terminal 86.
  4. Command the trunk to RELEASE with a scan tool. The test lamp should illuminate during the RELEASE command.
    • If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, replace the K9 body control module.
    • If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K9 body control module.
  5. If all circuits test normal, test or replace the KR95B rear compartment lid unlatch relay.
