Supplemental Restraint System 9J-121
DISCRIMINATING SENSOR -FORWARD SENSOR RH
WARNING: DURING SERVICE PROCEDURES, BE VERY CAREFUL WHEN HANDLING A SENSOR. NEVER
STRIKE OR JAR A SENSOR. UNDER SOME CIRCUMSTANCES, IT COULD CAUSE DEPLOYMENT AND
RESULT IN PERSONAL INJURY OR IMPROPER OPERATION OF THE SUPPLEMENTAL RESTRAINT SYSTEM(
SRS ). ALL SENSOR AND MOUNTING BRACKET BOLTS MUST BE CAREIFULLY TORQUED TO ASSURE
PROPER OPERATION. NEVER POWER UP
THE SRS WHEN ANY SENSOR IS NOT RIGIDLY ATTACHED TO
VEHICLE, SINCE
THE SENSOR COULD BE ACTIVATED WHEN NOT ATTACHED AND COULD RESULT IN
DEPLOYMENT.
WARNING: PROPER OPERATION
OF THE SENSORS AND SUPPLEMENTAL RESTRAINT SYSTEM( SRS)
REQUIRES
THAT ANY REPAIRS TO THE VEHICLE STRUCTURE RETURN IT TO ITS ORIGINAL PRODUCTION
CONFIGURATION. DEPLOYMENT (CURRENT CODE
51 )OR ANY VISIBLE DAMAGE TO SENSOR AND/OR
THEIR
MOUNTING BRACKETS REQUIRES REPLACEMENT, NOT REPAIR. PROPER OPERATION OF A
SENSOR ALSO REQUIRES THAT SENSOR BE RIGIDLY BOLTED TO THE VEHICLE STRUCTURE. THE ARROW
ON
THE SENSOR MUST BE POINTING TOWARD THE FRONT OF THE VEHICLE. FAILURE TO OBSERVE
THESE PRECAUTIONS CAN RESULT IN IMPROPER SRS OPERATION AND POSSIBLE LACK OF
SUPPLEMENTAL RESTRAINT PROTECTION FOR THE DRIVER AND PASSEMGER DURING AN ACCIDENT
IMPACT.
All
sensors are specifically calibrated and are keyed to the sensor location and SRS wiring harness. Caution should
be used to ensure proper location of the sensors. The keying of the sensor to their locations and wiring harness
connectors
should never be modified in the filed.
REMOVAL
1. Disable the SRS. (Refer to "Disabling the SRS
"
in this section.)
2. Remove front grille.
3. Remove Head lamb Assembly.
4. Remove condenser fixing bolts.
5. Remove front end engine hood stay fixing
bolts.
6. Remove harness clip.
7. Disconnect harness connector.
8. Remove forward sensor fixing bolts and for­
ward sensor RH.

tighten to specified torque.
Torque: 30N·m{22 lb·ft.).
2. Connect harness connector.
3. Install harness clip.
4. Install front end engine hood stay fixing bolts.
5. Install condenser fixing bolts.
6. Install Head Lamb Assembly.

DRIVER INFLATOR MODULE
WARNING: SAFETY PRECAUTIONS MUST BE FOLLOWED WHEN HANDLING A DEPLOYED INFLATOR
MODULE(AIR
BAG). AFTER DEPLOYMENT, THE INFLATOR MODULE(AIR BAG} SURFACE MAY CONTAIN A
SMALL AMOUNT OF SODIUM HYDROXIDE, A BY-PRODUCT OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO
THE SKIN AND EYES. MOST OF THE POWDER ON THE INFLATOR MODULE (AIR BAG )IS
HARMLESS.
AS A PRECAUTION, WEAR GLOVES AND SAFETY GLASSES WHEN HANDLING A DEPLOYED
INFLATOR MODULE (AIR BAG ), AND WASH YOUR HANDS WITH MILD SOAP AND WATER AFTERWARDS.
WARNING:
WHEN CARRYING A LIVE INFLATOR MODULE (AIR BAG }, MAKE SURE THE BAG AND TRIM
COVER
ARE POINTED AWAY FROM YOU. NEVER CARRY INFLATOR MODULE (AIR BAG )BY THE WIRES OR
CONNECTOR
ON THE UNDERSIDE OF MODULE. IN THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE BAG
WILL THEN DEPLOY WITH MINIMAL CHANCE OF INJURY. WHEN PLACING A LIVE INFLATOR MODULE (AIR
BAG ) ON A BENCH OR OTHER SURFACE, ALWAYS FACE BAG AND TRIM COVER UP, AWAY FROM THE
SURFACE.NEVER REST A STEERING COLUMN ASSEMBLY ON THE STEERING WHEEL WITH THE INFLATOR
MODULE (AIR BAG } FACE DOWN AND COLUMN VERTICAL. THIS IS NECESSARY SO THAT A FREE SPACE
IS PROVIDED TO
ALLOW THE INFLATOR MODULE (AIR BAG} TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE:
In the event deployment has occurred, inspect coil assembly wire for any signs of scorching, melting or any
other damage due to excessive heat.
If the coil has been damaged, replace it.
REMOVAL
1. Disable the SRS. (Refer to "Disabling the SRS "
in this section.)
2. Remove inflator module (Air Bag) from steering
wheel by removing four bolts. Lift inflator module
(Air Bag) out of steering wheel.
3. Disconnect 2-way yellow connector and remove ~
inflator module (Air Bag).
INSTALLATION
1. Connect inflator module to wiring harness
connector.
2. Install inflator module into steering wheel and
torque fasteners.
Torque: 8N.m(69 lb.ln.)
3. Enable the SRS (Refer to "Enabling the SRS" in
this section.).
