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.
 
 
OPERATION
When the M.U.T.-IIISE 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 set 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.-IIISE CAN bus diagnostics
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 3.
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
Is diagnosis code No.C1392 or C1393 set?
Go to Step 3.
This diagnosis is complete.
 
STEP 3. Check the G sensor-related diagnosis code.
Use the M.U.T.-IIISE to check whether the G sensor-related diagnosis code is set or not.
Is the diagnosis code set?
Troubleshoot for the relevant diagnosis code (Refer to ).
Go to Step 4.
 
STEP 4. Check whether the ASC-ECU is installed properly.
Check whether the ASC-ECU is installed correctly. Refer to .
Is the check result normal?
Go to Step 5.
Repair it.
 
STEP 5. M.U.T.-IIISE data list
Check the following data list (Refer to ).
  • Item 06: G sensor offset
  • Item 08: Lateral G sensor
  • Item 09: G sensor
  • Item 20: Lateral G sensor offset
Is the check result normal?
Go to Step 6.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 6. Check whether the diagnosis code is set again.
Is diagnosis code No.C1392 or C1393 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
This diagnosis is complete.
