Circuit/System Testing

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the headlamp switch.
  2. Ignition OFF, test for less than 1 Ω of resistance between the ground circuit and ground.
    • If greater than 1 Ω, test the ground circuit for an open/high resistance.
  3. Verify the headlamps are OFF.
    • If the headlamps are not OFF, test the signal circuit for a short to ground. If the circuit tests normal, replace the BCM.
  4. Install a 3-amp fused jumper wire between the signal circuit and ground. Verify the headlamps are ON.
    • If the headlamps are not ON, test the signal circuit of the headlamp switch for a short to voltage or an open/high resistance. If circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the headlamp switch.
