SYSTEM OPERATION CHECK
When ignition is turned on, SRS indicator light should come on for about 6 seconds and then go off. If indicator does not come on, or does not go off after about 6 seconds or comes on while driving, air bag system must be inspected as soon as possible.
Turn ignition switch to ON position. AIR BAG indicator light should come on for about 4 seconds on A4 and about 10 seconds on A6, and then go out. If light flashes and then remains on, control unit has detected a system fault. If light does not glow, check bulb. If bulb is okay, diagnose air bag system.
Turn ignition switch to ON position. SRS is operational if warning light comes on and then goes out after about 4-6 seconds. There is a SRS malfunction if SRS warning light does not come on, comes on briefly or blinks and goes out, and then comes on and stays on. A SRS malfunction is also indicated if SRS warning light comes on and stays on or flickers while driving.
When ignition is turned on, SRS indicator light should come on for about 6 seconds and then go off. If indicator does not come on, or does not go off after about 6 seconds or comes on while driving, air bag system must be inspected as soon as possible.
When ignition is turned to on position SRS indicator light should flash 6 times, then turn off. If SRS indicator light does not function as stated or comes on during vehicle operation, a failure has occurred in SRS and must be repaired.
On QX4, turn ignition ON and verify that AIR BAG indicator light comes on for about 7 seconds, then goes off. On G20, I30, and Q45, turn ignition ON and verify that AIR BAG indicator light comes on for about 7 seconds, then goes off. The SEAT BELT indicator light and chime come on for about 7 seconds, then go off.
On all models, if AIR BAG indicator light does not come on or after about 7 seconds does not go out or begins to flash, a SRS malfunction has been detected.
On G20, I30, and Q45, if SEAT BELT indicator light does not come on or stays on longer than 7 seconds with seat belt fastened, a seat belt pretensioner malfunction has been detected. Diagnose and repair as necessary.
Turn ignition ON and verify that AIR BAG indicator light flashes 7 times, then turns off. AIR BAG indicator light should not come on during vehicle operation. If AIR BAG indicator light does not function as described, service air bag system.
When ignition is turned on, SRS indicator light will come on for about 6 seconds and then go off. If indicator does not come on, stays on after about 6 seconds or comes on while driving, an air bag system malfunction has been detected. Air bag system must be inspected as soon as possible.
Turn ignition on. AIR BAG warning light in instrument cluster should come on for 4-6 seconds and then turn off. If AIR BAG warning light does not function as described, repair air bag system.
Turn ignition switch to ON position. Air bag indicator light should come on for about 5 seconds and then go out. If a fault is detected, indicator light will come on and begin to blink. Diagnose and repair as necessary.
Turn ignition switch to ACC or ON position. Air bag indicator light in instrument cluster should come on for about 6 seconds, then go out. If indicator light remains on or flashes, a SRS malfunction has been detected. Diagnose and repair as necessary.
Turn ignition on. AIR BAG indicator light in instrument cluster should come on for 6 seconds and then turn off. On B Series Pickups, the passenger air bag deactivation switch will also light for about 6 seconds, and then turn off.
On all models, if AIR BAG indicator light does not come on, stays on or flashes, a SRS fault has been detected. Diagnose and repair as necessary.
Supplemental Restraint System (SRS) warning light indicates air bag and seat belt Emergency Tensioning Retractor (ETR) system readiness. Turn ignition on. SRS warning light will come on, and then go out after approximately 4 seconds indicating system is functioning properly.
If SRS warning light does not come on, comes on while driving or is on all the time (for crash related faults), there is a system fault. If SRS warning light stays on for a duration of approximately 2 minutes, a non-crash related fault is present. Repair malfunctioning system.
Some vehicles may be equipped with passenger-side/child safety seat air bag deactivation system. System requires a special child safety seat and a specially designed passenger front seat. When child seat is installed in passenger seat, the passenger-side front air bag is disabled.
When child seat IS properly installed, AIRBAG OFF indicator light will come on and stay on when ignition is in ON or RUN position. When child seat is NOT installed and ignition is turned on, AIRBAG OFF indicator light will come on for approximately 6 seconds and then go out.
Turn ignition on. SRS warning light on instrument panel should come on for about 7 seconds then turn off. This indicates SRS is functioning properly. If SRS warning light does not come on, stays on, or comes on while driving, SRS is malfunctioning and needs repair. Diagnose and repair as necessary.
Turn ignition on. AIR BAG warning light should come on for about 7 seconds and then go off, indicating SRS is okay. If AIR BAG warning light does not come on, service Supplemental Restraint System (SRS). If AIR BAG warning light stays on constantly, service SRS. If AIR BAG warning light comes on for about 7 seconds, goes off, then starts flashing, a fault code is set in memory. Diagnose and repair as necessary.
Note. On vehicles equipped with seat belt pretensioner, the seat belt warning light and chime should also come on for about 7 seconds and then go off (with seat belt fastened).
Turn ignition switch to ON position. AIR BAG light on instrument panel should come on for about 3 seconds and then go off. If AIR BAG light fails to come on, remains on after 3 seconds or comes on while driving, air bag system requires servicing. Diagnose and repair as necessary.
Turn ignition on. Supplemental Restraint System (SRS) warning light should come on for 3-4 seconds, then go out. If the light goes out and then comes back on, or does not come on at all, a fault exists in system. Diagnose and repair as necessary.
Turn ignition on. AIR BAG warning light in instrument cluster should come on and then go out after approximately 7 seconds. If AIR BAG warning light stays on for longer than 7 seconds, or does not come on, SRS is malfunctioning. Diagnose and repair as necessary.
Turn ignition switch to ON position. If system is functioning normally, AIR BAG indicator should flash 7 times (6 times on Esteem). If air bag warning light does not operate as specified, service air bag system.
Turn ignition switch to ACC or ON position. Air bag warning light should come on for about 6 seconds, then go out. If air bag warning light does not operate as specified, service air bag system.
An instrument cluster air bag light is used to indicate readiness of system. When ignition switch is first turned on, this light should glow for about 4 seconds, then go out. During this time, the air bag control unit performs an electronic test of system.
If the air bag light flashes for a further 15 seconds, this signals that the air bags or seat belts pretensioners are electronically disabled. If air bag light does not glow when ignition is on, or does not go out after about 4 seconds, a fault probably exists in system. If a fault occurs while ignition is on, it is stored in fault memory.
If warning light glows or flickers while driving, air bag system should be tested. Diagnose and repair as necessary.
Turn ignition switch to ON position (engine not running). If no fault codes are present, SRS warning light will go out after 10 seconds. If SRS is malfunctioning, SRS fault code will be stored in crash sensor memory. If SRS warning light indicates a malfunction, diagnose air bag system. Repair as necessary.
