Circuit/System Testing

  1. Clear the DTC. Disconnect the headlamp switch.
  2. Connect a DMM between the I/P dimming voltage reference circuit and the negative terminal of the battery.
  3. Ignition ON, test for 9-14 volts.
    • If less then 9 volts, test the I/P dimming voltage reference circuit for a short to ground or an open/high resistance. If the circuit/connections test normal, replace the BCM.
    • If greater than 14 volts, test the I/P dimming voltage reference circuit for a short to voltage. If the circuit/connections test normal, replace the BCM.
  4. Disconnect the DMM. Install a jumper between I/P dimming voltage reference circuit and the I/P dimming control circuit.
  5. Verify that DTC B3600 03 does not set.
    • If the DTC resets, then test for a short to ground in the I/P dimming control circuit. If the circuit/connections test normal, replace the BCM.
  6. If all circuits/connections test normal, replace the turn signal multi function switch.
