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.
5.CHECK WHEEL SENSOR HARNESS

3. Check continuity between ABS ac tuator and electric unit (control
unit) harness connector and ground.
OK or NG
OK >> Perform self-diagnosis again. If the same result appears, replace ABS actuator and electric unit (control
unit). Refer to BRC-54
.
NG >> Repair harness or connectors.
DTC C1113 G-SENSORINFOID:0000000001327682
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit
indicate a malfunction. However, this is not a malf unction, if normal operation can be resumed after
restarting engine.
INSPECTION PROCEDURE
1.CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or wh en on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-III the yaw rate
sensor system might be displayed, but in this case ther e is no malfunction in yaw rate sensor circuit.
As soon as vehicle leaves turntable or moving object , restart engine to return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END
