SUPPLEMENTAL RESTRAINT SYSTEM
9J–33
Service Precaution
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 SUPPLEMENTAL RESTRAINT SYSTEM
(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 Sensing and Diagnostic Module (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
“SRS–1" 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.
6. Remove SRS fuse METER and SRS, from left dash
side lower fuse block or disconnect battery.
7. Disconnect yellow 2–pin connector at the base of
steering column.
8. Remove glove box assembly; Refer to “Passenger
Air Bag Assembly Replacement" in this section.
9. Disconnect passenger air bag assembly yellow 2–
pin connector behind the glove box assembly.
CAUTION: With the “SRS" 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.
3. Connect yellow 2–pin connector at the base of the
steering column.
4. Install “AIR BAG" fuse METER and SRS to left dash
side lower fuse block or connect battery.
Turn ignition switch to “ON" and verify that the “AIR
BAG" warning lamp flashes seven times and then turns
“OFF" If it does not operate as described, perform the
“SRS Diagnostic System Check" in section.
Handling / Installation / Diagnosis
5. Air bag assembly should not be subjected to
temperatures above 93
°
C (200
°
F
).
6. Air bag assembly, and SDM should not be used if
they have been dropped from a height of 100 cm
(3.3 feet) or more.
7. When a SDM is replaced, it must be oriented with
the arrow on the SDM pointing toward the front of
the vehicle. It is very important for the SDM to be
located flat on the mounting surface, parallel to the
vehicle datum line. It is important that the SDM
mounting surface is free of any dirt or other foreign
material.
8. 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.
9. The “SRS Diagnostic System Check" must be the
starting point of any SRS diagnostics. The “SRS
Diagnostic System Check" will verify proper “AIR
BAG" 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 replacements.
Inspections Required After An Accident
CAUTION: Certain SRS components must be
replaced after a frontal crash involving air bag
deployment.
In all types of accidents regardless of “Air Bag"
deployment, visually inspect all of the following
components and replace as required:
– Driver air bag assembly
– Passenger air bag assembly
– Steering wheel
– SRS coil assembly
– Steering column
– Knee bolster and instrument panel mounting
attachments
– Driver seat and belt
– Passenger seat and belt
– SDM
