3B-6 POWER-ASSISTED STEERING SYSTEM
Steering Column

RTW 53BLF000901
WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLE-SHOOTING THE SRS SYSTEM, DO NOT
USE ELECTRICAL TEST EQUIPMENT, SUCH AS
A
BATTERY-POWERED OR A/C-POWERED
VOLTMETER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPECIFIED
IN THIS MANUAL. DO NOT USE A NON-POWERED
PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.
W hen servicing a vehicle equipped with a Supplemental
Restraint System, pay close attention to all W ARNINGS
and CAUTIONS.
For detailed explanations about SRS, refer to Restraints
section.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted conveniently on the column.
3. W ith the column mounted lock, the ignition and steering operation can be locked to prevent theft o
f
the vehicle.
The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use
only the specified screws, bolts and nuts as designated,
and tighten them to the specified torque.
Handle the column with care when it is removed from
the vehicle. A sharp blow on the end of the steering
shaft or shift lever, or dropping the assembly could
shear or loosen the fasteners that maintain column
rigidity.

POWER-ASSISTED STEERING SYSTEM 3B-27
Supplemental Restraint System Steering Wheel & Column
Service Precaution
This steering wheel and column repair section covers
the Supplemental Restraint System (SRS) steering
column. The following repair procedures are specific to
SRS components. W hen servicing a vehicle equipped
with Supplemental Restraint System, pay close attention
to all W ARNINGS and CAUTIONS.
For detailed explanation about SRS, refer to Restraints
section.
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNECESSARY SRS SYSTEM
REPAIRS.
SAFE HANDLING OF INFLATOR MODULES
REQUIRES THE PROCEDURES DESCRIBED
BELOW TO BE FOLLOWED FOR BOTH LIVE AND
DEPLOYED MODULES.
SAFETY PRECAUTIONS MUST BE FOLLOWED
WHEN HANDLING A DEPLOYED AIR BAG
ASSEMBLY (AIR BAG). AFTER DEPLOYMENT, THE
AIR BAG ASSEMBLY (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 AIR BAG ASSEMBLY (AIR BAG) IS HARMLESS.
AS A PRECAUTION, WEAR GLOVES AND SAFETY
GLASSES WHEN HANDLING A DEPLO
YED AIR BAG
ASSEMBLY, AND WASH YOUR HANDS WITH MILD
SOAP AND WATER AFTERWARDS.

WHEN CARRYING A LIVE AIR BAG ASSEMBLY,
MAKE SURE THE BAG AND TRIM COVER ARE
POINTED AWAY FROM YOU. NEVER CARRY AN AIR
BAG ASSEMBLY 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 AIR BAG ASSEMBLY ON
A
BENCH OR OTHER SURFACE, ALWAYS FACE THE
BAG AND TRIM COVER UP, AWAY FROM THE
SURFACE.
NEVER REST A STEERING COLUMN ASSEMBLY
ON THE STEERING WHEEL WITH THE AIR BAG
ASSEMBLY FACE DOWN AND COLUMN VERTICAL.
THIS IS NECESSARY SO THAT A FREE SPACE IS
PROVIDED TO ALLOW THE AIR BAG ASSEMBLY
TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. OTHERWISE,
PERSONAL INJURY COULD RESULT.
TO AVOID DEPLOYMENT WHEN
TROUBLESHOOTING THE SRS SYSTEM, DO NOT
USE ELECTRICAL TEST EQUIPMENT, SUCH AS
A
BATTERY-POWERED OR A/C-POWERED VOLT-
METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPECIFIED
IN THIS MANUAL. DO NOT USE A NON-POWERED
PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.

SRS Connectors
CAUTION: The special yellow color connectors are
used for the supplemental restraint system-air bag
circuit.
When removing the cable harness, do not pull the
cables. Otherwise, cable disconnection may occur.
When connecting the SRS connector, insert the
connector completely. Imperfect locking may cause
malfunction of the SRS circuit.

POWER-ASSISTED STEERING SYSTEM 3B-29
Removal
1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to "LOCK".
3. Disconnect the battery "-" terminal cable, and wait at least 5 minutes (with SRS air bag).
4. Disconnect the yellow 2-way SRS connector located under the steering column (with SRS air bag).
CAUTION: The wheels of the vehicle must be
straight ahead and the steering column in the
"LOCK" position before disconnecting the steering
wheel. Failure to do so will cause the coil assembly
to lose its centering which will cause damage to the
coil assembly (with SRS air bag).
5. Disable the SRS (Refer to "Disabling the SRS" in this section) (with SRS air bag).
6. Check the holes on both sides of the steering cove
r
(with SRS air bag).

7. Check the position of the pins in their holes. Push
the pin in the direction of the arrow (with SRS ai
r
bag).

RTW 73BSH000101
8. Push the four pins with a φ 5~6 mm (0.20~0.24 in)
bar (with SRS air bag).
060R300031
9. Cancel the lock to release the four pins (with SRS air bag).

5. Enable the SRS (Refer to "Enabling the SRS" in this
section) (with SRS air bag).
6. Connect the SRS connector (with SRS air bag).
7. Connect the battery "-" terminal cable (with SRS ai
r
bag).
8. Turn the ignition switch to "ON" while watching warning light and check - the light should flash 7
times and then go off. If lamp does not operate
correctly, refer to Restraints section.
