Turn Signal Switch: Service and Repair

Turn Signal Switch/Cornering Light Switch (Combination Switch)


Removal

1. Disconnect the battery ground cable.




2. Remove the instrument panel driver lower cover (5). Refer to the Instrument Panel Assembly in Body Structure.
3. Remove seven screws to remove the steering cowl (4).
4. Disconnect the SDM (air bag controller) connector located at lower of the instrument panel driver lower cover.
5. Remove four fixing screws and disconnect the driver inflator module connector to remove the driver inflator module (3).

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 minimum 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.

6. Remove the steering wheel (2). Refer to the Steering Wheel in Steering action.
7. Disconnect the SRS coil assembly connector, remove four fixing screws to remove the SRS coil assembly (1).

8. Disconnect the lighting switch connector, remove four fixing screws to remove the lighting switch (6).

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) counterclockwise fully until it stops.




Then from where it stops, turn it back about 3 rotations to set the alignment marks (7) together before installing the steering wheel.

2. Tighten the steering shaft nut to the specified torque.

Torque: 34 N.m (25 lb ft)

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 (11), be sure to pass the harnesses through the route as shown in the figure so that the starter switch harness (8), the combination switch harness (9) and inflator module harness (10) will not get caught.
