Instrument Cluster Test 13A - High Beam Indicator Light
NOTE:
Perform INSTRUMENT CLUSTER TEST 4A
before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION
For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, TEST VER-1A - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition on with engine off. Turn headlights high beam on. If headlights high beam illuminate, go to next step. If headlights high beam do not illuminate, see HEADLIGHT SYSTEMS wiring diagram under WIRING DIAGRAMS .
- Using scan tool, read HI BEAM SENSE. If high beam sense is ON, go to next step. If high beam sense is not ON, go to step 5).
- Turn ignition switch to UNLOCK position. Using scan tool, actuate ALL LAMPS. If high beam indicator light illuminates, system is operating properly. If high beam indicator light does not illuminate, go to next step.
- Disconnect instrument cluster and ensure connectors are clean and not damaged. See Figure in INSTRUMENT CLUSTER TEST 8A. Remove and inspect high beam indicator bulb. If bulb is defective, replace bulb. If bulb is okay, repair or replace instrument cluster.
- Turn headlights and ignition off. Disconnect BCM from junction block. Turn headlights high beam on. Turn ignition on with engine off. Using scan tool in voltmeter mode, measure voltage at terminal No. 1 on junction block 12-pin internal connector. See Figure in CHIME TEST 3A. If voltage is 10 volts or less, replace junction block. If voltage is more than 10 volts, replace BCM.
