On–Vehicle Service
Service Precaution
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 UNNECESSARY SRS
REPAIRS.
The SRS control unit in Driver–Passenger SRS can
maintain sufficient voltage to cause a deployment fo
r
up to 15 seconds after the ignition switch is turned
“OFF,” the battery is disconnected, or the fuse
powering the SRS control unit is removed.
Many of the service procedures require removal of the
“SRS” fuse, and disconnection of the air bag assembl
y
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 “LOCK” and remove the
key.
1. Remove the SRS fuse “SRS”, from the side of the driver’s side of the instrument panel fuse block o
r
disconnect the battery.
2. Disconnect the yellow connector at the base of the steering column.
3. Remove the glove box assembly, refer to “Passenger Air Bag Assembly Replacement” in
this manual.
4. Disconnect the yellow connector behind the glove box assembly.
CAUTION: With the “SRS” fuse removed and
ignition switched “ON”, the “SRS” warning lamp
will be “ON”. This is normal operation and does
not indicate an SRS malfunction.

Enabling The SRS
Installation
CAUTION: Never use the air bag assembly from
another vehicle or different model year air bag
assembly.
Use only a new air bag assembly matched to the
TFR/S which is being repaired.
Turn the ignition switch to “LOCK” and remove the
key.
1. Connect the yellow connector passenger air bag assembly.
2. Install the glove box assembly. Refer to “Passenger air bag assembly replacement” in this

4. Install the “AIR BAG” fuse “SRS” to the side of the driver’s side of the instrument panel fuse block o
r
connect the battery.
Turn the ignition switch to “ON” and verify that the
“SRS” warning lamp flashes seven times and then
turns to “LOCK”. If it does not operate as described,
perform the “SRS Diagnostic System Check” in this
manual.

Handling / Installation / Diagnosis
1. The air bag assembly should not be subjected to temperatures above 65
°C (150°F).
2. The air bag assembly, and SRS control unit, should not be used if they have been dropped from
a height of 100 centimeters (3.28 feet) or more.
3. W hen the SRS control unit is replaced, it must be oriented with the arrow on the sensor pointing
toward the front of the vehicle. It is very important
for the SRS control unit to be located flat on the
mounting surface, parallel to the vehicle datum
line. It is important that the SRS control unit
mounting surface is free of any dirt or other foreign
material.
4. Do not apply power to the SRS unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble
code.
5. The “SRS Diagnostic System Check” must be the starting point of any SRS diagnostics. The “SRS
Diagnostic System Check” will verify proper “SRS”
warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in
extended diagnostic time, incorrect diagnosis, and
incorrect parts replacement.
