DIAGNOSIS CODE PROCEDURES

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 ).

• Whenever ECU is replaced, ensure that the 

CAN bus lines are normal.

• When the hydraulic unit (integrated with 

ASC-ECU) is replaced, always carry out the 
calibration of the steering wheel sensor, the G 
and yaw rate sensor and brake fluid pressure 
sensor (Refer to 

P.35C-93

, 

P.35C-94

 and 

P.35C-94

).

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 ASC-ECU. ASC-ECU uses 
the frequency of the pulse signals to determine 
the wheel speed.

DIAGNOSIS CODE SET CONDITIONS

ASC-ECU monitors the voltage fluctuation in each 
wheel speed sensor circuit. If ASC-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

• Malfunction of ASC-ECU

Past trouble

• Carry out diagnosis with particular emphasis on 

wiring harness and connector failures between 
ASC-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 ).

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the CAN bus lines (Refer to GROUP 
54C 

− CAN Bus Diagnostics Table ). On 

completion, go to Step 2.

STEP 2. Diagnosis code recheck after resetting 
CAN bus lines

Q: Is diagnosis code No. C100A, 1015, 1020 or 102B 

set?
YES : 

Go to Step 3.

NO : 

This diagnosis is complete.

STEP 3. M.U.T.-III data list
Check the following data list (Refer to 

P.35C-85

).

• Item No.01: FL wheel speed sensor

• Item No.02: FR wheel speed sensor

• Item No.03: RL wheel speed sensor

• Item No.04: RR wheel speed sensor

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Go to Step 4.

STEP 4. Voltage measurement at the ASC-ECU 
connector (FL+, FL-, FR+, FR-, RL+, RL-, RR+, 
RR- terminal)
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Turn the ignition switch to the ON position.
