DIAGNOSIS CODE PROCEDURES

Code No. C100A FL wheel speed sensor circuit

Code No. C1015 FR wheel speed sensor circuit

Code No. C1020 RL wheel speed sensor circuit

Code No. C102B RR wheel speed sensor circuit

CAUTION

If there is any problem in the CAN bus lines, an
incorrect diagnosis code may be set. Prior to this
diagnosis, diagnose the CAN bus lines (Refer to
GROUP 54C

− CAN Bus Diagnostics Table ).

OPERATION

• The wheel speed sensor is a kind of a pulse gen-

erator. It consists of encoders (a plate on which
north and south pole sides of the magnets are
arranged alternately) for detecting the wheel
speed which rotates at the same speed of the
wheels and wheel speed sensors. This sensor
outputs frequency pulse signals in proportion to
the wheel speed.

• The pulse signals, which the wheel speed sensor

creates, are sent to ABS-ECU. ABS-ECU uses
the frequency of the pulse signals to determine
the wheel speed.

DIAGNOSIS CODE SET CONDITIONS

ABS-ECU monitors the voltage fluctuation in each
wheel speed sensor circuit. If ABS-ECU detects the
open or short circuit in the circuit, it will set a diagno-
sis code.

PROBABLE CAUSES

Current trouble

• Damaged wiring harness and connectors

• Noise interference

• Malfunction of wheel speed sensor

• ABS-ECU malfunction

Past trouble

• Carry out diagnosis with particular emphasis on

wiring harness and connector failures between
ABS-ECU and the wheel speed sensor. For diag-
nosis procedures, refer to How to treat past trou-
ble (GROUP 00

− How to Use

Troubleshooting/How to Treat Past Trouble ).
