CAUTION:

• Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause yaw rate/side/decel G

sensor circuit indicate a malfunction. However this is not a malfunction if normal operation can be
resumed after restarting engine.

• When on a turntable, such as at a parking structure entrance, or when on a moving object with

engine running, the VDC OFF indicator lamp might turn on and self-diagnosis using the CONSULT-III
yaw rate sensor system malfunction might be displayed, but in this case there is no malfunction with
yaw rate/side/decel G sensor circuit. As soon as the vehicle leaves the turntable or moving object,
restart the engine to return the system to normal.

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) connector.

3.

C1115 WHEEL SENSOR

Description

INFOID:0000000006263423

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).

Select “ABS” and “DATA MONITOR”, check “FR LH SENSOR”, “FR RH SENSOR”, “RR LH SENSOR”
and “RR RH SENSOR” with CONSULT-III.
NOTE:
Set the “DATA MONITOR” recording speed to “10 msec”.

5.

Read a value (wheel speed) of both normal wheel sensors and error-detecting wheel sensor. 

Regarding the deference at 30 km/h (19 MPH) between the wheel speed detected by the error detecting
wheel sensor and the maximum/minimum wheel speed detected by the normal wheel sensors, is the differ-
ence within 5%, respectively?

YES

>> GO TO 4.
