SYSTEM OPERATION CHECK 

Turn ignition on. AIR BAG warning light in instrument cluster should come on for 4-8 seconds and then turn 
off. If AIR BAG warning light does not function as described, repair air bag system.  

SERVICE PRECAUTIONS 

Observe the following precautions when servicing SRS:  

z

Disable SRS before servicing any SRS or steering column component. Failure to do this could result in 
accidental air bag deployment and possible personal injury. See DISABLING & ACTIVATING AIR 
BAG SYSTEM .  

z

After turning ignition switch to LOCK position, disconnecting negative battery cables, and turning 
headlight switch on, wait at least 10 MINUTES before servicing vehicle. SRS is equipped with a back-up 
power source that may allow air bag to deploy within 10 MINUTES after disconnecting negative battery 
cable.  

z

In a minor collision in which air bags did not deploy, inspect front air bag sensors and steering wheel pad. 

z

NEVER use air bag components from another vehicle. Replace air bag components with NEW 
components.  

z

Never disassemble or repair system components. Replace cracked, dented or otherwise damaged system 
components.  

z

DO NOT expose air bag components to heat or flame, high humidity or electrical noise.  

z

After servicing SRS, check air bag warning light to ensure system is functioning properly. See SYSTEM 
OPERATION CHECK .  

z

Always wear safety glasses when servicing or handling an air bag.  

z

When placing a live air bag on a bench or other flat surface, always face air bag trim cover up, away from 
surface. This will reduce motion of module if it is accidentally deployed.  

z

After deployment, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always 
wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. After clean-up, wash hands 
using mild soap and water.  

z

When carrying a live air bag module, trim cover must be pointed away from body to minimize injury in 
case of accidental air bag deployment.  

z

If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and 
again becomes operational. DO NOT remove bulbs, modules, sensors or other components or in any way 
disable system from operating normally. If SRS is not functional, park vehicle until it is repaired and 
functions properly.  

NOTE:

When SRS C-21 or SRS-1 fuse is removed and ignition switch is in ON position, 
AIR BAG indicator light will be on. This is a normal operation and does not 
indicate an SRS malfunction.

DISABLING & ACTIVATING AIR BAG SYSTEM 

To disable SRS, turn ignition switch to LOCK position. Disconnect negative battery cable and then positive 
battery cable. Wait at least 10 MINUTES before servicing vehicle. To ensure a complete SRS back-up power 
supply discharge, turn headlights on. To activate SRS, ensure headlights are turned off. Connect positive battery 
cable and then negative cable. Perform SYSTEM OPERATION CHECK .  

LEXUS 

SYSTEM OPERATION CHECK 

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.  

SERVICE PRECAUTIONS 

Observe the following precautions when servicing SRS:  

z

Disable SRS before servicing any SRS, instrument panel or steering column component. Failure to do this 
could result in accidental air bag deployment and possible personal injury. See DISABLING & 
ACTIVATING AIR BAG SYSTEM .  

z

Before disconnecting battery check for SRS diagnostic trouble codes.  

z

DO NOT use any type of back-up power supply from outside vehicle to avoid memory loss in memory 
systems. Back-up power supplies can provide enough voltage to activate SRS components.  

z

After turning ignition switch to LOCK position and disconnecting negative battery cable, wait at least 90 
SECONDS before working on vehicle. SRS is equipped with a back-up power source that may allow air 
bag to deploy within 90 seconds after disconnecting negative battery cable.  

z

In a minor collision in which air bags did not deploy, inspect front air bag sensors and steering wheel pad. 

z

Remove air bag sensors if an impact is likely to be applied to area close to sensors during repair.  

z

Never disassemble or repair system components. Replace cracked, dented or otherwise damaged system 
components.  

z

DO NOT expose front air bag sensors, center air bag sensor assembly, steering wheel pad, passenger-side 
air bag, side air bags or seat belt pretensioners directly to hot air or flame.  

z

DO NOT store air bag modules where they will be exposed to temperatures greater than 199°F (93°C), 
high humidity or electrical noise. DO NOT store seat belt pretensioners to temperatures greater than 176°
F (80°C), high humidity or electrical noise.  

z

Information labels are attached to air bag components. Follow all notices on labels.  

z

After servicing SRS, check air bag indicator light to ensure system is functioning properly. See SYSTEM 
OPERATION CHECK .  

z

Always wear safety glasses when servicing or handling air bags or seat belt pretensioners.  

z

When placing a live air bag on a bench or other flat surface, always face air bag and trim cover up, away 
from surface. This will reduce motion of module if it is accidentally deployed.  

z

After deployment, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always

DO NOT install components previously installed on another vehicle. Only use NEW components 
supplied by manufacturer.  

z

When using electric welding, disconnect air bag module and seat belt pretensioner connectors.  

z

When carrying a live air bag module, trim cover must be pointed away from body to minimize injury in 
case of accidental air bag deployment.
