Air Bag(s) Arming and Disarming: Service and Repair
CAUTION: When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced,
use the correct part number fastener for that application. If the correct part number fastener is not available, a fastener of equal size and strength (or
stronger) may be used. fasteners that are not reused, and those requiring thread locking compound will be called out. The correct torque value must be
used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.
WARNING: WHEN PERFORMING SERVICE ON OR AROUND SRS COMPONENTS OR SRS WIRING, FOLLOW THE PROCEDURES
LISTED BELOW TO TEMPORARILY DISABLE THE SRS. FAILURE TO FOLLOW PROCEDURES COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver-Passenger SRS can maintain sufficient voltage to cause a deployment for up to 15 seconds after the ignition switch is turned "OFF,"
the battery is disconnected, or the fuse powering the SDM is removed.
Many of the service procedures require removal of the "C-21" fuse, and disconnection of the air bag assembly from the deployment loop to avoid an
accidental deployment. If the air bag assembly is disconnected from the deployment loop as noted in the "Disabling the SRS" procedure that follows,
service can begin immediately without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to "OFF" and turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
1. Remove SRS fuse "C-21" from left dash side lower fuse block or disconnect battery.
2. Disconnect yellow 2-pin connector at the base of steering column.
3. Remove glove box assembly; Refer to "Passenger air bag assembly replacement" in this section.
4. Disconnect passenger air bag assembly yellow 2-pin connector behind the glove box assembly.
CAUTION: With the "C-21" fuse removed and ignition switch "ON," the "AIR BAG" warning lamp will be "ON." This is normal operation and
does not indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to "LOCK" and remove key.
1. Connect yellow 2-pin connector passenger air bag assembly.
2. Install glove box assembly. Refer to "Passenger Air Bag Assembly Replacement" in this section.
