REMOVAL AND INSTALLATION
caution
  • Disconnect the negative (-) battery terminal and wait for 60 seconds or more before starting work. Insulate the disconnected (-) terminal by wrapping the tape (Refer to the item 5 of Service Precautions ).
  • Never attempt to disassemble or repair the air bag module and clock spring. If faulty, replace it with new one.
  • Do not drop the air bag module or clock spring or allow contact with water, grease or oil. If denting, cracking, or deformation is discovered, replace it with new one.
  • Store the air bag module on a flat surface with the deployment surface facing up. Also, do not put anything on it.
  • Do not store the air bag module in a place more than 93°C.
  • When the driver's air bag have been deployed, replace the driver's air bag module with new one. Also, check the clock spring, and replace with a new part if there is an abnormality.
  • Put on gloves and safety glasses when handling deployed air bag.
  • When discarding the air bag module, make sure to deploy the air bag before the disposal (Refer to ).
 
 
Pre-removal operation
  • Check that the front wheels are at the straight-ahead position.
  • Turn the ignition switch to the "LOCK" (OFF) position.

<<A>> DRIVER'S AIR BAG MODULE REMOVAL
caution
  • Never use an electric tester to diagnose the air bag module circuit. Never attempt to disassemble the air bag module.
  • Be sure to store the removed air bag module in a clean and dry place with a pad surface facing upward.
  • When discarding the air bag module, discard after deploying the air bag as specified in the service procedure (Refer to ).
 
Follow the procedure below according to the item numbers in the illustration.
1. Insert a TORX (screw)driver (T-30) into the service hole on the steering wheel assembly.
2. Use the TORX (screw)driver (T-30) to press the rod in driver’s air bag module.
3. When the driver’s air bag module is disengaged, the driver’s air bag module will be released.
4. Repeat for the other service hole end then remove the driver’s air bag module.
 

 
 
<<B>> DRIVER'S AIR BAG MODULE CONNECTOR REMOVAL
 
1. Use the flat-tipped screwdriver to pull out the locking button of wiring harness side connector, and release the lock.
 

 
 
<<C>> STEERING WHEEL ASSEMBLY REMOVAL
1.
cautionUse the special tool to remove the steering wheel since the steering column collision absorbing mechanism may be damaged.
Position the steering wheel in a straight ahead direction.
 
2. Using special tool steering wheel puller (MB990803), remove the steering wheel assembly as shown in the figure.
 

 
 
<<D>> CLOCK SPRING REMOVAL
cautionThe removed clock spring should be stored in a clean, dry place.
 
Lift the connector lock of clock spring connector to the direction of the arrow, then unlock and disconnect the connector.
 
 
 
 
INSTALLATION SERVICE POINTS
 
 
>>A<< PRE-INSTALLATION INSPECTION
1. Before the installation, check the air bag module and clock spring (Refer to ).
noteEven when installing a new air bag module or clock spring, perform an inspection before the installation.
2.
cautionBe sure to turn the ignition key to the "LOCK" (OFF) position when connecting or disconnecting M.U.T.-IIISE.
Connect M.U.T.-IIISE to the diagnosis connector (16 pin).
3. Turn the ignition switch to the "ON" position.
4. Read the diagnosis code, and check that everything is normal except the air bag module open circuit.
5. Turn the ignition switch to the "LOCK" (OFF) position.
 

 
 
>>B<< CLOCK SPRING INSTALLATION
 
1.
caution
  • If the centre of the clock spring is not correctly aligned, the steering wheel may not be turned fully or the cable inside the clock spring may be broken, causing the SRS airbag to be inoperative or operated incorrectly.
  • When aligning the clock spring neutral position mark, perform with the clock spring independently. If performed with the steering wheel sensor installed, the steering wheel sensor may be damaged.
Align the mating marks of the clock spring according to the procedure below:
(1)
cautionDo not rotate the clock spring by 2.5 turns or more clockwise from its centre position. If you fail to do this, the cable inside the cock spring may be broken.
Turn the clock spring anti-clockwise fully.
(2) Rotate the clock spring approximately 3.6 turns clockwise to align the mating marks.
(3) Check that the white cable can be seen from the both window for checking the neutral point when the mating marks are aligned.
noteIf the white or black cable can be seen from either window, the neutral point is not aligned correctly.
(4) Install the clock spring to the column switch.
 

 
 
>>C<< STEERING WHEEL ASSEMBLY INSTALLATION
 
1.
cautionWhen installing the steering wheel assembly, do not trap the clock spring harness.
After checking that the clock spring centre alignment is already performed, install the steering wheel assembly so that its boss part is aligned with the rib of the clock spring slowly.
2. After the installation, check that there is no abnormality when the steering wheel is fully turned to left and right.
 

 
 
>>D<< POST-INSTALLATION INSPECTION
cautionAfter the maintenance of the SRS air bag and seat belt with pre-tensioner is completed, be sure to delete the diagnosis code and check whether the SRS warning lamp lights up (Refer to ).
1. Turn the ignition switch to the "ON" position.
 
2. Check that the SRS warning lamp is illuminated for 6 to 8 seconds, and extinguished afterward.
3. If the lamp does not extinguish, perform the troubleshooting (Refer to ).
