Instrument Cluster Test 11A - Seat Belt Warning 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 switch from OFF position to ON (RUN) position. If seat belt warning light illuminates and then goes off, system is operating properly. If seat belt warning light does not illuminate, go to next step.
- Turn ignition switch to UNLOCK position. Using scan tool, actuate ALL LAMPS. If seat belt warning light does not illuminate, go to next step. If seat belt warning light illuminates, replace Body Control Module (BCM) on Breeze, Cirrus or Stratus models. On Sebring Convertible, go to step 4).
- Turn ignition off. Disconnect instrument cluster and ensure connectors are clean and not damaged. Remove and inspect seat belt warning light bulb. See Figure in INSTRUMENT CLUSTER TEST 8A. If bulb is defective, replace bulb. If bulb is okay, repair or replace instrument cluster as necessary.
- Disconnect seat belt control module (SBCM) connector under center console. See Figure in DOOR AJAR TEST 2A. Connect jumper wire between ground and terminal No. 11 (Light Green wire) on SBCM harness connector. If seat belt warning light goes out, see PASSIVE RESTRAINT SYSTEM for futher diagnosis. If seat belt warning light is still illuminated, go to next step.
- Disconnect instrument panel 22-pin connector at Body Control Module (BCM). See Figure in CHIME TEST 3A. Using external ohmmeter, measure resistance between ground and terminal No. 9 (Light Green wire) on 22-pin harness connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open Light Green wire.
- Disconnect jumper wire. Using external ohmmeter, measure resistance between ground and terminal No. 9 (Light Green wire) on 22-pin harness connector. If resistance is less than 5 ohms, repair Light Green wire for short to ground. If resistance is 5 ohms or greater, replace Body Control Module (BCM).
