WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While removing cylinder body never depress brake pedal because piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer to BR-25, "
BRAKE BURNISHING PROCEDURE" .

PRECAUTIONS
Revision: 2005 July 2005 FX

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, VDC/TCS/ABS
function may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

If the following components are replaced with non-genuine components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc.), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).

Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may
not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or VDC OFF indicator lamp and SLIP
indicator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after
restarting engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malfunction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.

Adjustment of Steering Angle Sensor Neutral PositionAFS001S9
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
× : Required
–: Not required
CAUTION:
To adjust neutral position of steering angle sensor, make sure to use CONSULT-II.
(Adjustment can not be done without CONSULT-II.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition switch ON (do not start engine).
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-II screen in this order. Refer to BRC-26, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”. CAUTION:
Do not touch steering wheel while adjusting steering angle
sensor.
5. After approximately 10 seconds, touch “END”. (After approxi- mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-II screen. Then make sure “STR ANGLE SIG” is within 0 ±3.5 deg. If value is more than specification, repeat steps 3
to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.
Calibration of Decel G Sensor (AWD Model)AFS001TQ
NOTE:
After removing/installing or replacing yaw rate/side/decel G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel alignment, make sure to calibrate of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONSULT-II. (Adjustment can not be done without CON-
SULT-II.)

The work should be done at a horizontal place when vehicle is in the unloaded vehicle condi-
tion.

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure
value.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition switch ON (do not start engine).
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
3. Touch “ABS”, “WORK SUPPORT” and “DECEL G-SEN CALIBRATION” on CONSULT-II screen in this order. Refer to BRC-26, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”. CAUTION:
Set vehicle as shown in the display.

Be sure to perform above operation.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “DECEL G-SEN” on CONSULT-II screen. Then make sure “DECEL G-SEN” is within 0 ±0.08 G. If value is
more than specification, repeat steps 3 to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.
