NOTE
The steering column must be removed to remove the lock cylinder.

All models are equipped with a Supplemental Restraint System (SRS), which comprises a driver airbag and a front passenger airbag. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to serious injury. Further, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate when required. Before performing servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct procedures described in the repair manual.



Work must be started no sooner than 90 seconds after the ignition switch is turned to the LOCK position and the negative battery cable is disconnected from the battery. The SRS is equipped with a back-up power source that will discharge completely 90 seconds after disconnecting the battery.
 
Do not expose the steering wheel pad, front passenger airbag assembly, airbag sensor assembly or front airbag sensor directly to hot air or flames.
 
Malfunction symptoms of the SRS are difficult to confirm, so the warning light and DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
 
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, airbag sensor assembly and front airbag sensor should be inspected.
 
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.
 
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
 
Never disassemble or attempt to repair an airbag assembly or airbag sensor.
 
If the steering wheel pad, front passenger airbag assembly, airbag sensor assembly or front airbag sensor, has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace it with new one.
 
Use a volt/ohmmeter with high impedance (10,000 ohms/volt minimum) for troubleshooting the system-s electrical circuits.
 
Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.
 
After work on the SRS is completed, check the SRS warning light check.
 
When the negative cable is disconnected from the battery, the memory of the clock and audio system will be canceled. Before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each memory system, never use a back-up power supply from outside the vehicle.
 


NOTE
If the airbag connector is disconnected with the ignition switch ON , fault codes will be recorded.

  1. Disconnect the negative battery cable.
  2.  
  3. Place the front wheels facing straight ahead.
  4.  
  5. Using a T30 Torx® socket, loosen the 2 screws until the groove along the screw circumference catches on the screw case.
