RUNNING LIGHT UNIT INSPECTION

BME091866731202

1. Remove the bracket and pull it toward you.

2. Measure the voltage at the running light unit terminals as indicated below.

3. Disconnect the running light unit connector before inspecting for continuity at terminals 1C and 1D.

4. If not as specified, inspect the parts listed under "Action."

  • If the parts and wiring harnesses are okay but the system still does not work properly, replace the running light unit.
