  1. Ignition OFF, disconnect the PAL harness connector.
  2. Ignition ON, verify that a test lamp illuminates between the PAL B+ circuit terminal and ground.
    • If the test lamp does not illuminate, test the B+ circuit for an open/high resistance.
  3. Verify that a test lamp illuminates at both PAL ground circuit terminals and B+.
    • If the test lamp does not illuminate, test the ground circuits for an open/high resistance.
  4. If all circuits test normal, replace the PAL.
