TROUBLE DIAGNOSIS FOR SYSTEM
DTC C1101 RR RH SENSOR-1
INFOID: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 voltage 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). Check 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 approximately 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

1.
Turn ignition switch OFF and disconnect malfunctioning wheel
sensor connector E46 (FR-LH), E33 (FR-RH) or B69 (RR) and
ABS actuator and electric unit (control unit) connector E56.
2.
Check continuity between terminals. (Also check the continuity
when steering wheel is turned right and left and when sensor
harness inside wheel well is moved.)
OK or NG
OK
>> GO TO 6.
NG
>> Repair or replace harness and connector that have malfunction.
6.
CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1.
Disconnect malfunctioning wheel sensor connector.
2.
Turn ignition switch ON and check voltage between wheel sen-
sor harness connector power supply terminal and ground.
OK or NG?
OK
>> Replace wheel sensor.
NG
>> Replace ABS actuator and electric unit (control unit).
