Removal and Replacement

CAUTION:
1. Never attempt to disassemble or repair the air bag module or clock spring. If faulty, replace it.
2. Do not drop the air bag module or clock spring or allow contact with water, grease or oil. Replace it if a dent, cracks, deformation or rust are detected.
3. The air bag modules should be stored on a flat surface and placed so that the pad surface is facing upward.
Do not place anything on top of the air bag modules.
4. Do not expose the air bag module to temperature over 93°C (200°F).
5. After deployment of an air bag, replace the clock spring.
6. Wear gloves and safety goggles when handling an air bag that has deployed.
7. An undeployed air bag module should only be disposed of in accordance with the specified procedures.

REMOVAL AND INSTALLATION
Air Bag Module (Driver's Side), Clock Spring

Pre-removal Operation
- Set the steering wheel and the front wheels to the straight ahead position, and then remove the ignition key.

Air Bag Module And Clock Spring:




Clock Spring Removal Steps
- Post-installation inspection
1. Negative (-) battery cable connection
2. Air bag module (Driver's side)
3. Steering wheel
4. Column cover lower
5. Clock spring and body wiring harness connection
6. Clock spring
- Pre-installation inspection

Air Bag Module (Driver's Side) Removal Steps
- Post-installation inspection
1. Negative (-) battery cable connection
2. Air bag module (Driver's side)
- Pre-installation inspection

Air Bag Module (Front Passenger's Side)

Air Bag Module (Front Passenger's Side):




Air Bag Module (Front Passenger's Side) Removal Steps
- Post-installation inspection
1. Negative (-) battery cable connection
7. Air bag module (Front passenger's side)
- Pre-installation inspection




Step 1: Negative (-) Battery Cable Disconnection
Disconnect the negative battery cable from the battery and tape the terminal.

CAUTION: Wait at least 60 seconds after disconnecting the battery cable before doing any further work.

Step 2: Air Bag Module (driver's Side) Removal
1. Remove the air bag module mounting nut using a socket wrench from the back side.




2. When disconnecting the connector of the clock spring from the air bag module, press the air bag's lock toward the outer side to spread it open. Use a flat-tipped screwdriver to pry so as to remove the connector gently.

CAUTION:
1. When disconnecting the air bag module-clock spring connector, take care not to apply excessive force to it.




2. The removed air bag module should be stored in a clean, dry place with the pad cover facing up.




Step 3: Steering Wheel Removal

CAUTION: Do not hammer on the steering wheel. Doing so may damage the collapsible column mechanism.




Step 7: Air Bag Module (Front Passenger's Side) Removal

CAUTION: The removed air bag module should be stored in a clean, dry place with the pad cover facing up.

PRE-INSTALLATION INSPECTION
1. When installing the new air bag module and clock spring, refer to "INSPECTION".

CAUTION: Dispose of an air bag module only according to the specified procedure.

2. Connect the battery (-) terminal.




3. Connect the scan tool to the data link connector, then check diagnostic codes.

CAUTION: Turn the ignition switch oft before disconnecting or connecting the scan tool.

4. Turn the ignition key to the "ON" position.
5. Conduct diagnostic test mode using the scan tool to ensure entire SRS operates properly, except open circuit of air bag module (diagnostic trouble code No.22, 25).




6. Turn the ignition key to the "LOOK" position, disconnect the negative battery cable and tape the terminal.

CAUTION: Wait at least 60 seconds after disconnecting the battery cable before doing any further work.




Step 6: Clock Spring Installation
Align the mating marks of the clock spring, and, after turning the front wheels to the straight-ahead position, install the clock spring to the column switch.

Mating Marks Alignment
Turn the clock spring clockwise fully, and then turn back it approx. 3 1/8 turns counterclockwise to align the mating marks.

CAUTION: If the clock spring's mating marks are not properly aligned, the steering wheel may not be completely rotational during a turn, or the flat cable within the clock spring may be severed, obstructing normal operation of the SRS.

Step 3: Steering Wheel Installation
1. Before installing the steering wheel, be sure to first turn the vehicle's front wheels to the straight-ahead position and align the mating marks of the clock spring.

CAUTION: Be sure when installing the steering wheel, that the harness of the clock spring does not become caught or tangled.

2. After installing, turn the steering wheel all the way in both directions to confirm that steering is normal.

Air Bag Module (Driver's Side):




Step 2: Air Bag Module (Driver's Side) Installation
Install the air bag module, taking care that the wiring is not pinched.




POST-INSTALLATION INSPECTION
1. After installing the clock spring, the steering wheel, the column covers and the air bag module, check steering wheel for noise, binds or difficult operation.
2. Reconnect the negative battery terminal. Turn the ignition key to the "ON" position. Does the "SRS" warning light illuminate for about 7 seconds, turn OFF and then remain OFF? If yes, SRS system is functioning properly. If no, consult Diagnostic Function.

INSPECTION




Air Bag Module Check
If any improper part is found during the following inspection, replace the air bag module with a new one.
Dispose of the old one according to the specified procedure.

CAUTION: Never attempt to measure the circuit resistance of the air bag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental air bag deployment will result in serious personal injury.
1. Check pad cover for dents, cracks or deformation.
2. Check the air bag module for dents, cracks or deformation.
3. Check hooks and connectors for damage, terminals for deformation, and harness for binds.
4. Check air bag inflator case for dents, cracks or deformation.




5. Install the air bag module on the steering wheel to check alignment with the wheel.




Clock Spring Check
If, as result of the following checks, even one abnormal point is discovered, replace the clock spring with a new one.
1. Check connectors and protective tube for damage, and terminals for deformation.
2. Visually check the case for damage.







3. Check for continuity between the No.1 connector of the clock spring and connectors No.3 and 4.




4. Check resistance between the terminals.
a. Align the paint mark of the SRS check harness connector No. 4 with the clock spring connector No. 2 (arrow in the illustration) to connect the connectors Nos. 2 and 4.
b. Check continuity between the terminals 22 and 23 of the SRS check harness connector No. 5.
Standard value: less than 0.4 ohm
