When placing a live inflator module on a bench
or other surface, always face the bag and trim
cover up, away from the surface. This is neces­
sary so that a free space is provided to allow the
air bag to expand in the unlikely event of acci·
dental
deployment.
4. Steering wheel
• Refer to STEERING WHEEL REPLACEMENT in
Section 3F4.
5. Lighting switch (Combination switch)
• Disconnect the switch connector.
• Remove four screws.
• Remove the lighting switch together with SRS
coil assembly.
'\f CAUTION:
Do not remove SRS coil assembly from the com·
bination switch assembly.
E) INSTALLATION
To install, follow the removal steps in the reverse
order, noting the
following points.
1. Check to see if the vehicle is in the straight driving
condition and turn the rotary section of the SRS
coil assembly provided to the upper surface ofthe
lighting switch (combination switch) clockwise
fully until it stops. Then from where it stops, turn
it back about 3 rotations to set the alignment
marks together before installing the steering
wheel. (Fig. 8-83)
