Adjustment of Steering Angl
e Sensor Neutral PositionINFOID:0000000001327658
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.
CAUTION:
To adjust neutral position of steering angl e sensor, make sure to use CONSULT-III.
(Adjustment can not be done without CONSULT-III.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Touch “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-III screen in this order.
3. Touch “START”. CAUTION:
Do not touch steering wheel whil e adjusting steering angle sensor.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
5. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
6. Run vehicle with front wheels in straight-ahead position, then stop.
7. Select “DATA MONITOR”, “SELECTION FROM ME NU”, and “STR ANGLE SIG” on CONSULT-III screen.
Then make sure “STR ANGLE SIG” is within 0 ± 3.5 deg. If value is more than specification, repeat steps
1 to 6.
8. Erase memory of ABS actuator and electric unit (control unit) and ECM.
9. Turn ignition switch OFF.
Calibration of Decel G Sensor (AWD Models)INFOID:0000000001327659
NOTE:
After removing/installing or replacing yaw rate/side/dec el G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel ali gnment, make sure to calibration of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONS ULT-III. (Adjustment can not be done without CON-
SULT-III.)
1. Stop vehicle with front wheels in straight-ahead position.
CAUTION:
The work should be done at a horizontal place when vehicle is in the unloaded vehicle condition.
Keep all tires inflated to correct pressures. Ad just the tire pressure to the specified pressure
value.
2. Touch “WORK SUPPORT” and “DECEL G-SEN CALI BRATION” on CONSULT-III screen in this order.
3. Touch “START”. CAUTION:
Set vehicle as shown in the display.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)

CONSULT-III Functions (ABS)INFOID:0000000001327671
CONSULT-III MAIN FUNCTION
CONSULT-III can display each diagnostic item us ing the diagnostic test modes shown following.
Self-DiagnosisINFOID:0000000001327672
OPERATION PROCEDURE
Before performing the self-diagnosis, start engine and driv e vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
ERASE MEMORY
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 indi-
cator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicably 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 br ake waning lamp will not turn OFF even when the sys-
tem is normal unless the vehicle is driving at approxim ately 30 km/h (19 MPH) or more for approximately 1
minute.
Brake warning lamp will turn ON in case of parki ng brake operation (when switch is ON) or of brake fluid
level switch should not stay “ON” position.
VDC OFF switch should not stay “ON” position.

TROUBLE DIAGNOSIS FOR SYSTEM
TROUBLE DIAGNOSIS FOR SYSTEM
DTC C1101 RR RH SENSOR-1INFOID:0000000001327677
After using the CONSULT-III SELF-DIAG RESULTS to
determine the location of the malfunctioning wheel sen-
sor, check all areas to determine the component to be replaced.
CAUTION:
Do not measure the resistance value and also vo ltage between sensor terminal with tester etc.,
because sensor is an active sensor.
Do not expand terminal of connector with a tester terminal stick, when it does the inspection with
tester.
INSPECTION PROCEDURE
1.CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear, and size within the standard values?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2.CHECK SENSOR AND SENSOR ROTOR
Check condition of the sensor mount (for looseness, etc.).
Check surface of front sensor rotor rubber for damage.
Check rear sensor rotor for damage.
OK or NG
OK >> GO TO 3.
NG >> Repair sensor mount or replace sensor rotor.
3.CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 4.
NO >> INSPECTION END
4.CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector and malfunctioning wheel sensor con-
nector E46 (FR-LH), E33 (FR-RH) or B69 (RR). Chec k terminal for deformation, open circuit, poor con-
tact, etc., and repair or replace if any malfunctioning condition is found.
2. Reconnect connectors, drive at a speed of approximatel y 30 km/h (19 MPH) or more for approximately 1
minute, and perform self-diagnosis.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.
