B: CAUTION

• Before disassembling or reassembling parts, always disconnect the battery ground cable from battery.

  When replacing the audio, control module and other parts provided with memory functions, record the memory contents before disconnecting the battery ground cable. Otherwise, the memory is cleared.

• Reassemble the parts in the reverse order of disassembly procedure unless otherwise indicated.
• Adjust parts to the given specifications.
• Connect the connectors securely during reassembly.
• After reassembly, make sure that the functional parts operate normally.
• Yellow connectors and harnesses with yellow tapes around them are the connectors and harnesses for the airbag system. Using a tester above such circuits may cause malfunction of airbag system. Follow the cautions for the airbag system in this case. <Ref. to AB-9, CAUTION, General Description.>
• Be careful not to damage the airbag system wiring harness when servicing electrical parts and switches.

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.>

1. Using a hexagon wrench etc. wrapped by protective tape, insert the snap pins and release the locks (3 locations).

2. 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

1. Disconnect the connector and remove the nut.
2. Put alignment marks and remove the steering wheel using a steering puller.

6) Remove the cruise control command switch.

1. Remove the screw, disconnect the connector and remove the paddle shift switch. (Model with paddle shift)

2. Disconnect the claws and then remove the lower cover.

3. Remove the screw to remove the cruise control command switch assembly.

B: INSTALLATION

1) Install each part in the reverse order of removal.

CAUTION:

• Before handling the airbag module, refer to "CAUTION" of "General Description" in "AIRBAG SYSTEM".

  <Ref. to AB-9, CAUTION, General Description.>

• Do not allow harness and connectors to interfere or get tangled up with other parts.

2) Before installing steering wheel, be sure to adjust the direction of roll connector with steering. <Ref. to AB- 101, ADJUSTMENT, Roll Connector.>

Tightening torque:
Steering wheel: 39 N*m (3.98 kgf-m, 28.8 ft-lb)

Clearance:
Between column cover and steering wheel: 2 - 4 mm (0.08 - 0.16 in)

C: INSPECTION

1) Disconnect the cruise control command switch connector.

2) Check the resistance between cruise control command switch terminals.

Preparation tool: Circuit tester

3) Replace the cruise control command switch if the inspection result is not within the standard value.
