SRS AIR BAG SYSTEM SYSTEM DIAGRAM PASSENGER-SIDE S-SENSOR AIR BAG MODULE I IG1 B+ HORN RELAY CLOCK SPRING BACK-UP BATTERY I AIR BAG SYSTEM WARNING LIGHT SENSOR -7 System Operation During collision When either of the D-sensors and the S-sensor are activated (closed) simultaneously by shock of a colli- sion, the circuit to the inflator is completed. The inflator creates nitrogen gas and the air bag is deployed. The air bag vents the nitrogen gas from the vent hole on the back side of the bag to reduce shock to the driver and to allow easier exit from the vehicle. During normal condition and malfunction The diagnostic module constantly monitors the components and wiring of the air bag system for malfunc- tion, open circuits, and short circuits. .J If a malfunction is detected, the diagnostic module illuminates or flashes the warning light. In the case of a short circuit in the sensors or sensor harnesses, the diagnostic module activates the warning light and shuts down the system to prevent accidental deployment of the air bag.

T SRS AIR BAG SYSTEM GENERALPROCEDURES Before Servicing 1. Deactivate the audio antitheft system, if installed. (Refer to page T-120.) 2. Disconnect the negative battery cable. 3. Remove the lower panel. 4. Disconnect the orange and blue clock spring connec- tors. 5. Remove the glove compartment. 6. Disconnect the orange and blue passenger-side air bag module connectors. I , 46UOTXd21 TROUBLESHOOTING Troubleshootinn Procedure The air bag diagnostic module has a self-diagnosis function that flashes or illuminates the AIR BAG sys- tem warning light to indicate trouble in the air bag system. The trouble can be determined by the warning light illumination or flashing pattern. If the light does not illuminate but the system still has trouble, a warn- ing buzzer will sound 5 cycles of 5 times each. . . Flowchart I START Troubleshoot warning light circuit Does AIR BAG system warning light illuminate for 4-8 secs and I I Yes t Refer to service code table and troubleshoot system Press horn switch while turning steering wheel. Does horn sound? I I I Yes Reconnect connectors Are air bag module and horn switch connectors properly con- nected to clock spring connec- tor?
