Circuit/System Testing

  1. Ignition ON, turn the headlamp switch to the HEAD position.
  2. Rotate the I/P dimmer switch to the high and then low illuminations settings. The I/P back lighting should brighten and dim with each rotation.
    • If the back lighting does not change intensity, test the instrument panel lamp supply voltage circuit for a short to voltage.
  3. If the circuit tests normal, replace the BCM.
