Cruise Control Command Switch
A: REMOVAL
1) Position the front wheels straight ahead. (After moving a vehicle 5 m (16
ft) or more with front wheels positioned
straight ahead, make sure that the vehicle moves straight ahead.)
2) Turn the ignition switch to OFF.
3) Disconnect the ground cable from battery and wait for at least 60 seconds
before starting work.
4) Remove the driver's airbag module assembly.
CAUTION:
Before handling the airbag module, refer to "CAUTION" of "General Description"
in "AIRBAG SYSTEM".
<Ref. to AB-9, CAUTION, General Description.>
- Using a hexagon wrench etc. wrapped by protective tape, insert the snap
pins and release the locks
(3 locations).
- Disconnect the horn harness and airbag connector and remove the airbag
module assembly. <Ref. to
AB-18, PROCEDURE, Airbag Connector.>
5) Remove the steering wheel.
CAUTION:
- Always use the steering wheel puller for removal to avoid deforming
the steering wheel.
- If the steering wheel has been removed, make sure that the roll
connector is not turned from the
original position.
Preparation tool: Steering wheel puller
- Disconnect the connector and remove the nut.
- Put alignment marks and remove the steering wheel using a steering
puller.
6) Remove the cruise control command switch.
- Remove the screw, disconnect the connector and remove the paddle shift
switch. (Model with paddle
shift)
