BRC-226

< PRECAUTION >

[TYPE 2]

PRECAUTIONS

• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as

sharp curves on a freeway), the VDC may not operate normally, or the VDC warning lamp and the SLIP indi-

cator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the engine.

• Sudden turns (such as spin turns, acceleration turns), drifting, etc. with VDC turned off may cause the yaw

rate/side/decel G sensor to indicate a problem. This is not a problem if normal operation can be resumed

after restarting the engine.

• If battery is removed or steering angle sensor is disconnected, power to steering angle sensor is lost and the

screen goes into steering angle sensor safe mode.

• When screen goes into steering angle sensor safe mode, perform "Adjustment of Steering Angle Sensor

Neutral Position" with CONSULT and check that VDC OFF indicator turns off. Additionally, perform self-diag-

nosis, check that only "Steering Angle Sensor Safe Mode" is shown for self-diagnostic result, and then

delete the memory. (If the self-diagnostic result shows an indication other than "Steering Angle Sensor Safe

Mode", repair the relevant part and restart self-diagnosis.) The steering angle sensor is released and returns

to normal condition by performing the above operation.

• When checking, if only "Steering Angle Sensor Safe Mode" is shown in the self-diagnostic result and VDC

OFF indicator is off, delete history of malfunction. This happens when battery power supply is lost and the

screen goes into Steering Angle Sensor Safe Mode, and then screen returns to normal mode automatically

by driving the vehicle in a straight forward direction [for approximately 30 seconds at 20 km/h (12 MPH) or

more] after power is supplied again.

NOTE:

VDC OFF indicator lamp is on when VDC OFF switch is on.

Precaution for CAN System

INFOID:0000000007356981

• Do not apply voltage of 7.0V or higher to terminal to be measured.

• Maximum open terminal voltage of tester in use must be less than 7.0V.

• Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.

• Area to be repaired must be soldered and wrapped with tape.

Make sure that fraying of twisted wire is within 110 mm (4.33 in).

• Do not make a bypass connection to repaired area. (If the circuit is

bypassed, characteristics of twisted wire will be lost.)

WHEEL SENSORS

Removal and Installation

INFOID:0000000007356984

REMOVAL

1. If removing the front wheel sensor, first remove the disc rotor to gain access to the front wheel sensor bolt.

Refer to

BR-47, "Removal and Installation of Brake Caliper and Disc Rotor"

2. If removing the rear wheel sensor, first remove the spare tire.
3. Remove the wheel sensor bolt.
4. Pull the wheel sensor out, being careful to turn it as little as possible.

CAUTION:

• Be careful not to damage wheel sensor edge or the sensor rotor teeth.

• Do not pull on the wheel sensor harness.

5. Disconnect the wheel sensor harness connector, then remove the wheel sensor harness from the mounts

and remove the wheel sensor.

• When removing the rear wheel sensor, both sensors must be removed as they are on the same har-

ness.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Inspect wheel sensor O-ring, replace wheel sensor if damaged.

• Before installing the wheel sensor, make sure no foreign materials (such as iron fragments) are

adhered to the pick-up part of the wheel sensor, to the inside of the wheel sensor hole or on the sen-

sor rotor in the wheel hub assembly.

• Clean wheel sensor hole and mating surface with brake cleaner and a lint-free shop rag. Be careful

that dirt and debris do not enter the axle or wheel hub assembly.

NOTE:

Apply a coat of suitable grease to the wheel sensor O-ring and mating hole.

DLN-463, "Removal and Installation"

CAUTION:

Discard side oil seal.

2. Remove the sensor rotor from the side flange, using suitable tool with Tool.

Installation

1. Install the new sensor rotor on the side flange using Tools and a

suitable press as shown. Make sure the sensor rotor is fully

seated on the side flange.

CAUTION:

2. Install the side flange on the final drive assembly. Refer to

DLN-463, "Removal and Installation"

CAUTION:

Do not reuse the side oil seal. The side oil seal must be replaced every time the side flange is

removed from the final drive assembly.
