DRL Control Module Inspection

  1. Measure the voltage at the DRL control module terminals as indicated below.
  2. Disconnect the DRL control module connector before inspecting for continuity at terminal 1E.
    • 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 DRL control module.
