TROUBLESHOOTING
ACTIVE STABILITY CONTROL SYSTEM (ASC)
35C-51
YES :
Replace the hydraulic unit (integrated with
), and then
go to Step 10.
NO :
Intermittent malfunction (Refer to GROUP
00
− How to Use Troubleshooting/How to
Cope with Intermittent Malfunctions ).
STEP 10. Check whether the diagnosis code is
reset.
(1) Erase the diagnosis code.
(2) Turn the steering wheel to either right or left at 20
km/h or more.
NOTE: The ASC warning/operation lamp and the
ASC OFF lamp may remain on until the vehicle
speed reaches approx. 10 km/h, then the steer-
ing wheel is turned to either right or left.
Q: Is the diagnosis code No.C123C set?
YES :
Return to Step 1.
NO :
This diagnosis is complete.
Code No. C1392 Incomplete learn (Longitudinal G)
Code No. C1393 Incomplete learn neutral(Lateral G)
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
and
OPERATION
When the M.U.T.-III is operated, the ASC-ECU will
learn the neutral position of the G sensor and then
store it in its memory.
DIAGNOSIS CODE SET CONDITIONS
The ASC-ECU will store this diagnosis code when it
has not learned the neutral position of the G sensor.
PROBABLE CAUSES
• The neutral position of the G sensor has not been
learned.
• ASC-ECU malfunction
DIAGNOSIS 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.C1392 or C1393 set?
YES :
Go to Step 3
NO :
This diagnosis is complete.
STEP 3. Check the G sensor-related diagnosis
code.
Use the M.U.T.-III to check whether the G sen-
sor-related diagnosis code is set or not.
Q: Is the diagnosis code set?
YES :
Troubleshoot for the relevant diagnosis
code (Refer to
).
NO :
Go to Step 4
STEP 4. Check whether the ASC-ECU is installed
properly.
Check whether the ASC-ECU is installed correctly.
Refer to
Q: Is the check result normal?
YES :
Execute "Lateral G sensor calibration" and
"G sensor calibration" on "Special function".
After the calibration is performed (Refer to
) , turn the ignition switch from
"OFF" to "ON".Then go to Step 5.
NO :
Install the ASC-ECU properly, and execute
"Lateral G sensor calibration" and "G sensor
calibration" on "Special function". After the
calibration is performed (Refer to
)
, turn the ignition switch from "OFF" to
"ON".Then go to Step 5.
