NOTE: 

*

: When the diagnosis codes relating to the CAN communication error are output, make sure of the 

vehicle equipment. When the vehicle is not equipped with the system the ASC-ECU communicates to, the 
diagnosis code is always output. This is not abnormal.

DIAGNOSIS

TSB Revision

ACTIVE STABILITY CONTROL SYSTEM (ASC)

35C-22

CAUTION

• If there is any problem in the CAN bus lines, an incor-

rect diagnostic trouble code may be set. Prior to this 
diagnosis, diagnose the CAN bus lines (Refer to 
GROUP 54C 

− CAN Bus Line Diagnostic Flow 

P.54C-10

).

• 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 steer-
ing wheel sensor, the G and yaw rate sensor and brake 
fluid pressure sensor (Refer to 

P.35C-283

, 

P.35C-282

 

and 

P.35C-284

).

.

OPERATION

• The wheel speed sensor is a kind of a pulse generator. 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 fre-
quency 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.

.

DTC 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 diagnostic trouble code.

.

PROBABLE CAUSES

Current trouble

• Damaged wiring harness and connectors

• Noise interference

• Malfunction of wheel speed sensor

• ASC-ECU malfunction

Past trouble

• Carry out diagnosis with particular emphasis on wiring har-

ness and connector failures between ASC-ECU and the 
wheel speed sensor. For diagnosis procedures, refer to 
How to treat past trouble (GROUP 00 

− How to Use Trou-

bleshooting/How to Treat Past Trouble 

P.00-17

).

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

• MB991997: ASC check harness
