TROUBLESHOOTING

3. Otherwise, check the diagnosis code.

NOTE: 

.

*1

: The ABS warning lamp, ASC warning/opera-

tion lamp, ASC OFF lamp may stay ON until the 
vehicle speed reaches 10 km/h. As far as 
ASC-ECU stores any diagnosis code related to 
the wheel speed sensor malfunction or the motor 
malfunction as past trouble, ASC-ECU continues 
illuminating the ABS warning lamp until it verifies 
that the malfunction for that code is resolved 
(startup check).

If the steering wheel sensor or the G and yaw rate 

sensor system was detected to be defective dur-
ing ignition switch being ON at the last time, the 
ASC warning/operation lamp and the ASC OFF 
lamp will illuminate until the vehicle speed 
reaches approx. 10 km/h,  then the steering 
wheel is turned to either right or left and then the 
ECU determines that the system is normal.

*2

: The brake warning lamp does not turn OFF 

when the parking brake is applied or the brake 
fluid level is lowered.

DIAGNOSTIC FUNCTION

M1355001000880

ASC-ECU has the following functions for easier sys-
tem checks.

• Diagnosis code set (Refer to 

P.35C-15

).

• Service data output (Refer to 

P.35C-85

).

• Actuator test (Refer to 

P.35C-87

).

• Freeze frame data output (Refer to ).

All the above items can be diagnosed using 
M.U.T.-III.

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the 
M.U.T.-III.

When detecting fault and storing the diagnosis code, 
the ECU connected to CAN bus line obtains the data 
before the determination of the diagnosis code and 
the data when the diagnosis code is determined, and 
then stores the ECU status of that time. By analysing 
each data from M.U.T.-III, the troubleshooting can be 
performed more efficiently. The displayed items are 
as the table below.

FAIL-SAFE FUNCTIONS

• When a malfunction is determined by the diag-

nostic function, ASC-ECU illuminates the brake 
warning lamp, brake warning display, ABS warn-
ing lamp, ABS warning display, ASC warning 
lamp, ASC warning display, and ASC OFF lamp. 
At the same time, ASC-ECU prohibits the EBD, 
ABS, stability control, TCL, brake assist, and 
HSA.

NOTE: The brake warning lamp and brake warning 

display are used as the EBD control warning 
lamp.

• When the brake pad temperature (assumed) 

exceeds the specified value, the ASC OFF lamp 
flashes (2 Hz).
