NO.1 AIR BAG SYSTEM WARNING LIGHT DOES NOT ILLUMINATE

id0803a3800200

1 | Air bag system warning light does not illuminate.
DETECTION CONDITION | Malfunction in air bag system warning light circuit (short to ground)
POSSIBLE CAUSE | • SAS control module malfunction • Instrument cluster (print plate) malfunction • Short to ground circuit in wiring harness between instrument cluster and SAS control module

## Diagnostic Procedure

• When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while doing the inspection to discover whether poor contact points are the cause of any intermittent malfunction. If there is a problem, check to make sure connectors, terminals and wiring harness are connected correctly and undamaged.

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT OTHER WARNING AND INDICATOR LIGHTS CIRCUIT IN INSTRUMENT CLUSTER • Turn ignition switch to ON position. • Do other warning and indicator lights illuminate? | Yes | Turn ignition switch to LOCK position, then go to the next step.
No | Inspect instrument cluster power supply system and ground system, then go to Step 5.
2 | INSPECT SAS CONTROL MODULE Warning • Handling the air bag system components improperly can accidentally deploy the air bag modules and pre-tensioner seat belts, which may seriously injure you. Read the service warnings and cautions before handling the air bag system components. (See SERVICE WARNINGS.) (See SERVICE CAUTIONS.) • Turn ignition switch to LOCK position. • Disconnect the negative battery cable and wait for 1 min or more. • Remove the column cover. • Disconnect the clock spring connector. • Remove the glove compartment. • Disconnect the passenger-side air bag module connector. • Disconnect the driver and passenger-side side air bag module connectors. (Vehicles with side air bag) • Disconnect the driver and passenger-side curtain air bag module connectors. (Vehicles with curtain air bag) • Remove the B-pillar lower trims. (Vehicle with pre-tensioner seat belt) • Disconnect the driver- and passenger-side pre-tensioner seat belt connectors. (Vehicle with pre-tensioner seat belt) • Turn up floor covering. • Disconnect the all SAS control module connectors. • Connect the negative battery cable. • Turn ignition switch to ON position. • Do air bag system warning light illuminate? | Yes | Replace SAS control module, then go to Step 5. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
No | Go to the next step.
*3 | INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND INSTRUMENT CLUSTER FOR SHORT TO GROUND • Turn ignition switch to LOCK position. • Disconnect the negative battery cable. • Disconnect the instrument cluster connector. • Is there continuity between terminal 1O of instrument cluster connector and ground? | Yes | Replace wiring harness, then go to Step 5.
No | Go to the next step.
4 | INSPECT INSTRUMENT CLUSTER • Connect the instrument cluster connector. • Connect the instrument cluster connector terminal 1O to ground, then reconnect connector. • Connect the negative battery cable. • Does air bag system warning light illuminate with ignition switch ON? | Yes | Replace instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No | Go to the next step.
5 | CONFIRM THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR • Turn ignition switch to LOCK position. • Disconnect the negative battery cable and wait for 1 min or more. • Connect the all SAS control module connectors. • Connect the driver and passenger-side pre-tensioner seat belt connectors. (Vehicles with pre-tensioner seat belt) • Connect the driver and passenger-side curtain air bag module connectors. (Vehicles with curtain air bag) • Connect the driver and passenger-side side air bag module connectors. (Vehicles with side air bag) • Connect the passenger-side air bag module connector. • Connect the clock spring connector. • Connect the negative battery cable. • Turn ignition switch to ON position. • Does air bag system warning light operate properly? | Yes | Complete troubleshooting, then explain repairs to customer.
No | Recheck malfunction symptoms, then repeat from Step 1 if malfunction recurs.
