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. When servicing a vehicle equipped with
Supplemental Restraint System, pay close attention to all
WARNINGS 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 UNNEEDED SRS SYSTEM REPAIRS.

SAFE HANDLING OF INFLATOR MODULES
REQUIRES FOLLOWING THE PROCEDURES
DESCRIBED BELOW 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 DEPLOYED 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
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 supplemental restraint system-air bag
circuit.
When removing the cable harness disconnect the
connector by unlocking at two places, outside (1)
and inside (2). Do not pull the wires or disconnection
may occur.
When connecting the double lock type SRS connec-
tor, insert the connector completely then lock the
connector.  Imperfect locking may cause the SRS cir-
cuit to malfunction.
