Brake BurnishingINFOID:0000000009463695
CAUTION:
• Burnish contact surfaces between brake pads and disc brake rotor according to the following proce-
dure after refinishing the disc brake rotor, replacing brake pads or if a soft pedal occurs at very low
mileage.
• Be careful of vehicle speed. Br akes do not operate firmly/securely until pads and disc rotor are
securely seated.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on straight, flat road.
2. Depress the brake pedal until the vehicle stops.
3. Release the brake pedal for a few minutes to allow the brake components to cool.
4. Repeat steps 1 to 3 until pad and disc rotor are securely seated.

• When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

CONSULT Function (ABS)INFOID:0000000009463758
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
FUNCTION
CONSULT can display each diagnostic item us ing the following direct diagnostic modes.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number is displayed.
SELF DIAGNOSTIC RESULT
Operation Procedure
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
How To Erase Self Diagnostic Result
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure t hat the ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless
the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay in ON position.
Display Item List
Refer to BRC-45, "DTC Index".
DATA MONITOR
Direct Diagnostic Mode Description
ECU identification The ABS actuator and electric un it (control unit) part number is displayed.
Self Diagnostic Result The ABS actuator and electric unit (control unit) self diagnostic results are displayed.
Data Monitor The ABS actuator and elec tric unit (control unit) input/output data is displayed in real time.

Work support The settings for ABS actuator and electric unit (control unit) functions can be changed.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication is displayed.
Configuration • Read and save the vehicle specification (TYPE ID).
• Write the vehicle specification (TYPE ID) when replacing ABS actu ator and electric unit (con-
trol unit).
