Auto Headlamp Signal CKT Open

  1. Turn ignition on. Using scan tool, select BODY, BODY COMPUTER then SENSORS. Using scan tool, read AUTO HEADLAMP SENS VOLTS. If voltage is .6-4.8 volts, replace Body Control Module (BCM). BCM is located with junction block under driver's side instrument panel. See Figure . If voltage is not .6-4.8 volts, go to next step.
  2. Turn ignition off. Disconnect BCM connector "B". Inspect connector for damaged pins, corrosion and loose terminals. Repair connector as necessary. If connector is okay, turn ignition on. Connect a jumper wire between ground and terminal No. 51 (White/Light Green wire) at BCM connector "B". See Figure . Disconnect interior electrochromic (rear view) mirror connector. Inspect connector for damaged pins, corrosion and loose terminals. Repair connector as necessary. If connector is okay, measure resistance between ground and terminal No. 7 (Black/Dark Green wire) at interior electrochromic mirror connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black/Dark Green wire between interior electrochromic mirror connector and BCM.
  3. Remove jumper wire. Measure resistance between ground and terminal No. 7 (Black/Dark Green wire) at interior electrochromic mirror connector. If resistance is less than 1000 ohms, repair short to ground in Black/Dark Green wire between electrochromic mirror connector and BCM. If resistance is 1000 ohms or more, replace interior electrochromic mirror.
