SPECIAL TOOL(S)

REMOVAL

WARNING:
^ ALWAYS WEAR SAFETY GLASSES WHEN REPAIRING AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) VEHICLE AND WHEN HANDLING AN AIR BAG MODULE. THIS WILL REDUCE THE RISK OF INJURY IN THE EVENT OF AN ACCIDENTAL DEPLOYMENT.
^ CARRY A LIVE AIR BAG MODULE WITH THE AIR BAG AND TRIM COVER POINTED AWAY FROM YOUR BODY. THIS WILL REDUCE THE RISK OF INJURY IN THE EVENT OF AN ACCIDENTAL DEPLOYMENT.
^ DO NOT SET A LIVE AIR BAG MODULE DOWN WITH THE TRIM COVER FACE DOWN. THIS WILL REDUCE THE RISK OF INJURY IN THE EVENT OF AN ACCIDENTAL DEPLOYMENT.
^ AFTER DEPLOYMENT, THE AIR BAG SURFACE CAN CONTAIN DEPOSITS OF SODIUM HYDROXIDE, A PRODUCT OF THE GAS GENERANT COMBUSTION THAT IS IRRITATING TO THE SKIN. WASH YOUR HANDS WITH SOAP AND WATER AFTERWARDS.
^ NEVER PROBE THE CONNECTORS ON THE AIR BAG MODULE. DOING SO CAN RESULT IN AIR BAG DEPLOYMENT, WHICH CAN RESULT IN PERSONAL INJURY.
^ AIR BAG MODULES WITH DISCOLORED OR DAMAGED TRIM COVERS MUST BE REPLACED, NOT REPAINTED.

NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.

INSTALLATION

WARNING: TO REDUCE THE RISK OF SERIOUS PERSONAL INJURY, READ AND FOLLOW ALL WARNINGS, CAUTIONS AND NOTES AT THE BEGINNING OF THE REMOVAL PROCEDURE.

Vehicles receiving a new clockspring
1. Remove the key from the clockspring, holding the rotor in its centralized position.
^ Do not allow the clockspring rotor to turn.

NOTE: A new clockspring is supplied in a centralized position and held there with a key.

Vehicles needing clockspring recentering







2. Centralize the clockspring.
1 Hold the clockspring outer housing stationary.
2 While turning the rotor counterclockwise, carefully feel for the ribbon wire to run out of length and a slight resistance is felt. Stop turning at this point.

CAUTION: Overturning will destroy the clockspring. The internal ribbon wire acts as the stop and can be broken from its internal connection.

3 Turn the clockspring clockwise approximately three turns. This is the center point of the clockspring.
^ Do not allow the rotor to turn from this position.

WARNING: INCORRECT CENTRALIZATION MAY RESULT IN PREMATURE COMPONENT FAILURE. IF IN DOUBT WHEN CENTRALIZING THE CLOCKSPRING, REPEAT THE CENTRALIZING PROCEDURE. FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN PERSONAL INJURY.

CAUTION: Make sure the road wheels are in the straight ahead position.

NOTE: If a clockspring has rotated out of center, follow through with this step.

Vehicle repairs reusing the same clockspring
3. Remove the tape applied during clockspring removal.

NOTE: When the tape is removed, do not allow the clockspring to turn.
