  1. Ignition OFF, disconnect the harness connector at the appropriate headlamp assembly.
  2. Test for less than 5 Ω between the ground circuit terminal listed below and ground:
    • Left headlamp - terminal 4
    • Right headlamp - terminal 10
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Disconnect the harness connector at the headlamp right.
  4. Ignition ON, headlamps ON, connect a test lamp between the ignition circuit terminal 1 and ground. The test lamp should illuminate.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
