Low Beam Headlights Will Not Turn Off

  1. Connect scan tool to Data Link Connector (DLC). Using scan tool, retrieve Body Control Module (BCM) Diagnostic Trouble Codes (DTCs). If no DTCs exist, go to next step. If any DTCs exists, repair those before continuing. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table under SELF-DIAGNOSTIC SYSTEM.
  2. Ensure headlight switch is off. Using scan tool, check headlight switch voltage. If 4.3-4.8 volts is displayed, go to next step. If 4.3-4.8 volts is not displayed, replace headlight switch.
  3. Turn ignition off. Remove low beam relay from junction block. See Figure . If low beams are not illuminated, go to next step. If low beams are illuminated, repair short to voltage in wiring between low beam relay and headlights.
  4. Replace low beam relay with known-good unit. If low beams do not operate properly, go to next step. If low beams operate properly, replace low beam relay.
  5. Turn ignition off. Remove low beam relay. Disconnect Body Control Module (BCM) from back of junction block. Measure resistance between ground and terminal No. 14 at BCM connector on back of junction block. See Figure . If resistance is greater than 100 ohms, go to next step. If resistance is 100 ohms or less, replace junction block.
  6. Measure resistance between terminal No. 14 and each other terminal at BCM connector on back of junction block. If any resistance is less than 100 ohms, replace junction block. If all resistances are greater than 100 ohms, replace BCM.
