Combination Switch: Service and Repair

Preparation: Disconnect the battery ground cable.

1. Instrument panel driver lower cover
^ Refer to the removal steps of the "STARTER SWITCH".
2. Steering cowl
^ Remove seven screws.
3. Driver inflator module
^ Disconnect the inflator module connector located at lower of the instrument panel driver lower cover.
^ Remove four screws.
^ Disconnect the inflator module connector.

CAUTION: When carrying a live inflator module, make sure the bag opening is pointed away from you. In case of an accidental deployment, the bag will then deploy with minimal chance of injury. Never carry the inflator module by the wires or connector on the underside of the module.

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 necessary so that a free space is provided to allow the air bag to expand in the unlikely event of accidental deployment.
4. Steering wheel
^ Refer to "STEERING WHEEL REPLACEMENT" in SRS Steering wheel and Column system.
5. Lighting switch (Combination switch)
^ Disconnect the switch connector.
^ Remove four screws.
^ Remove the lighting switch together with SRS coil assembly.

CAUTION: Do not remove SRS coil assembly from the combination switch assembly.

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 of the lighting switch (combination switch) clockwise fully until it stops. Then from where it stops, turn it back about a rotations to set the alignment marks together before installing the steering wheel.
2. Tighten the steering shaft nut to the specified torque.

Nut torque N.m (lb.ft) = 34 (25)

3. When connecting the double lock type of inflator module connector, insert the connector completely and lock at outside. Imperfect locking may cause malfunction of SRS system circuit.




4. When installing the steering cowl, be sure to pass the harnesses through the route as shown in the illustration so that the starter switch, the combination switch and the inflator module harness will not get caught.
