PRECAUTIONS
 If the following components are replaced with non-genui
ne components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc. ), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).
 Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may not
operate properly.
 When the TCS or VDC is activated by sudden accele ration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
 When driving on roads which have extreme slopes (s uch as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate nor mally, or VDC OFF indicator lamp and SLIP indi-
cator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restart-
ing engine.
 Sudden turns (such as spin turns, acceleration turns) , drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malf unction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.
 Change 4 tires at a time. Be sure to use specified- size tires that have the same brand name and pattern.
Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the size
is different from the genuine tires.

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.
5.CHECK WHEEL SENSOR HARNESS
