High Beam Headlights Will Not Turn On
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition off. Remove circuit breaker No. 2 (25-amp) from fuse block. Check voltage at circuit breaker input terminal No. 43 in fuse block. If battery voltage exists, go to next step. If battery voltage does not exist, repair power supply circuit. See POWER DISTRIBUTION article in WIRING DIAGRAMS.
- Check circuit breaker No. 2 from fuse block. If circuit breaker is blown, go to next step. If circuit breaker is okay, go to step 5 .
- Disconnect Gray 20-pin multifunction switch connector located on steering column. Check resistance between multifunction switch harness connector terminal No. 16, low beam output circuit (Violet/White wire) and ground. See Fig 1 . If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, repair short to ground on Violet/White wire.
- Check resistance between multifunction switch harness connector terminal No. 17, high beam output circuit (Red/Orange wire) and ground. If resistance is more than 5 ohms, replace circuit breaker and recheck system. If resistance is 5 ohms or less, repair short to ground on Red/Orange wire.
- Install circuit breaker. Disconnect Gray 20-pin multifunction switch connector located on steering column. Check voltage at multifunction switch connector terminal No. 19 (Light Blue/Orange wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open on Light Blue/Orange wire between fuse block and multifunction switch.
- Using jumper wire, connect multifunction switch harness connector terminals No. 19 (Light Blue/Orange wire) and No. 17 (Red/Orange wire). If headlights illuminate, replace multifunction switch. If headlights do not illuminate, repair Red/Orange wire between multifunction switch and headlights.
