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 CAREFULLY 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 REPAI~. 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 PASSENGER 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 the transmission knob(for MIT) and
transfer control knob.
3. Remove front console assembly and disconnect
the wiring harness connector.
4. Pull lock tab up and push connector lock down to
disconnect connector.
5. Remove three DERM fixing screws and DERM. •d ...........

SRS COIL ASSEMBLY
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 the transmission knob(for
MIT) and
transfer
control knob.
3. Remove front console assembly and disconnect
the wiring harness connector.
4. Remove the steering lower cover and engine
hood opening
lever.
5. Remove inflator module (Air Bag) from steering
wheel by removing four bolts. Lift inflator module
(Air Bag) out of steering wheel.
6. Disconnect connector and remove inflator
module (Air Bag).
7. Disconnect horn lead
8. Remove steering wheel attachment nut.
9. Apply a setting mark across the steering wheel
and shaft so parts can be reassembled in their
original position.
10. Move the tires to the straight ahead position
before removing the steering
wheel and install
steering wheel puller onto steering wheel and
remove steering
wheel with J-29752.
11. Feed wiring through the wheel and remove
wheel.
CAUTION:
NEVER APPLY FORCE TO THE
STEERING WHEEL IN DIRECTION OF THE SHAFT
BY USING A HAMMER OR OTHER IMPACT TOOLS
~ IN AN ATTEMPT TO REMOVE THE STEERING
WHEEL. THE STEERING SHAFT IS DESIGNED AS
AN ENERGY ABSORBING UNIT.

12. Remove steering column cover.
13. Disconnect the wiring harness connectors ~
located base of steering column.
14. Remove the combination switch assembly with
SRScoil.
NOTE: SRS
coil is a part of combination switch
assembly, which
cannot be replaced individually.
Therefore, be sure not to remove the
SRS coil from the
combination switch assembly.
INSTALLATION
1. Install the combination switch assembly with
SRScoil.
2. Connect the wiring harness connector located In
base of steering column.
3. Turn the SRS coil clockwise to full, return about
3 turns and align the neutral mark.
CAUTION: WHEN TURNING THE SRS COIL
CLOCKWISE TO FULL, STOP TURNING IF
RESISTANCE IS FELT. FORCED FURTHER
TURNING MAY CAUSE DAMAGE TO THE CABLE IN
THE SRS COIL.
4. Install steering column cover.
CAUTION: WHEN INSTALLING THE STEERING
COLUMN COVER, BE SURE TO WIRE (THROUGH ~
EACH HARNESS) AS ILLUSTRATED SO THAT THE
HARNESSES OF STARTER SWITCH,COMBINATION
SWITCH
AND SRS COIL MAY NOT CATCH WIRING.
5. Install the steering wheel and align the setting
marks.
6. Tighten the steering fixing nut to the specified
torque.
Torque : 34N·m(25 lb·ft.).
7. Connect horn lead connector.
8. Connect inflator module to 2-way yellow wiring
harness connector.
9. Install inflator module into steering wheel and
torque fasteners.
NOTE: Always replace inflator module {Air Bag)
fasteners with new fasteners. Never reuse old fasteners.
Torque: 8N·m(69 lb·ln.)
10. Install the steering lower cover and engine hood
opening lever.
11. Install front console assembly and connect the
wiring harness connector.
12. Install the transmission knob{for M/T) and
transfer control knob. ~
13. Enable the SRS (Refer to "Enabling the SRS" in
this section.).
