CALIBRATION OF DECEL G SENSOR : Special Repair Requirement
INFOID:0000000001731366
CALIBRATION OF DECEL G SENSOR
CAUTION:
To calibrate the decel G sensor, make sure to use CONSULT-III
(Calibration cannot be done without CONSULT-III)
1.ALIGN THE VEHICLE STATUS
Stop vehicle with front wheels in straight-ahead position.
>> GO TO 2
2.PERFORM CALIBRATION OF DECEL G SENSOR
1. On the CONSULT-III screen, touch “WORK SUPPORT” and “DECEL G SEN CALIBRATION” in order.
2. Touch “START”.
3. After approximately 10 seconds, touch “END”.
NOTE:
After approximately 60 seconds, it ends automatically.
4. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to perform above operation.
>> GO TO 3
3.CHECK DATA MONITOR
1. Run vehicle with front wheels in straight-ahead position, then stop.
2. Select “DATA MONITOR”. Then make sure “DECEL G SEN” is within ±.
Is the inspection result normal?
YES >> GO TO 4
NO >> Perform calibration of decel G sensor again, GO TO 1
4.ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memory of the ABS actuator and electric unit (control unit) and ECM.
 ABS actuator and electric unit (control unit): Refer to BRC-25, "
CONSULT-III Function (ABS)".
 ECM, refer to:
-EC-107, "
CONSULT-III Function" (HR16DE with EURO-OBD)
-EC-462, "
CONSULT-III Function" (HR16DE without EURO-OBD)
-EC-772, "
CONSULT-III Function" (MR18DE)
-EC-1104, "
Diagnosis Description" (K9K)
Are the memories erased?
YES >> INSPECTION END
NO >> Check the items indicated by the self-diagnosis.

System DescriptionINFOID:0000000001731078
 Electric Brake force Distribution is a following function. ABS actuator and electric unit (control unit) detects
subtle slippages between the front and rear wheels during braking. Then it electronically controls the rear
braking force (brake fluid pressure) to reduce rear wheel slippage. Accordingly, it improves vehicle stability.
 Electrical system diagnosis by CONSULT-III is available.

CONSULT-III Function (ABS)INFOID:0000000001731081
FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF-DIAG RESULTS MODE
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-diagnosis Results
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 that 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,
VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the
system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-
mately 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 “ON” position.

Diagnostic test mode Function
Work supportThis mode enables a technician to adjust some devices faster and more accurately by following
the indications on CONSULT-III.
Self-diagnostic results Self-diagnostic results can be read and erased quickly.
Data monitor Input/Output data in the ABS actuator and electric unit (control unit) can be read.
Active testDiagnostic test mode is which CONSULT-III drives some actuators apart from the ABS actuator
and electric unit (control unit) and also shifts some parameters in a specified range.

DescriptionINFOID:0000000001731082
When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current
signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES >> Proceed to diagnosis procedure. Refer to BRC-30, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000001731084
CAUTION:
Do not check between wheel sensor terminals.
INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E125 and wheel sensor of malfunction-
ing code.
Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair or replace as necessary.
2.CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
