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 ).
  • If diagnosis codes U0100, U0101, U0114, U0126, U0317, U0141, U1004, U15A0 and U15A5 are set in ASC-ECU, always diagnose the CAN bus line. If there is any fault in the CAN bus lines, an incorrect diagnosis code may be set. In this case, the set diagnosis code is not highly reliable.
  • Before replacing the ECU, ensure that the communication circuit is normal.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set if ASC-ECU cannot receive the signal sent from other ECU for a certain period.
 
 
 
OPERATION
ASC-ECU communicates with the engine-ECU, CVT-ECU, AWC-ECU, steering wheel sensor, ETACS-ECU, electric parking brake ECU, ACC-ECU and FCM/LDW/AHB-ECU via the CAN bus lines.

  • Wiring harness or connector failure of CAN bus line
  • Engine-ECU malfunction
  • ASC-ECU malfunction

  • Malfunction of ETACS-ECU
  • ASC-ECU malfunction
Code No. U0317
  • Wiring harness or connector failure of CAN bus line
  • Malfunction of electric parking brake ECU
  • ASC-ECU malfunction
Code No. U1004
  • Wiring harness or connector failure of CAN bus line
  • Engine-ECU malfunction

  • ASC-ECU malfunction
 
 
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnosis
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
 
STEP 2. Check whether the diagnosis code is set again.
Is Code No. U0100, U0101, U0114, U0126, U0141, U0317, U1004, U15A0 or U15A5 set?
Go to Step 3.
The procedure is complete.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
Use M.U.T.-IIISE to check that other diagnosis code is set in the ECU corresponding to the relevant diagnosis.
Is other diagnosis code set?
Troubleshoot for the relevant diagnosis code.
Go to Step 4.
 
STEP 4. M.U.T.-IIISE diagnosis code
Use M.U.T.-IIISE to check if the same diagnosis code (time-out) is set in the other ECU.
Is any diagnosis code set?
YES (Code No. U0100 is set) : Replace the engine-ECU (Refer to GROUP 13A - Engine-ECU ), and then go to Step 5.
YES (Code No. U0101 is set) : Replace the CVT-ECU (Refer to GROUP 23A - CVT-ECU ), and then go to Step 5.
YES (Code No. U0114 is set) : Replace AWC-ECU (Refer to GROUP 23A - AWC-ECU (Refer to GROUP 23C - AWC-ECU ), and then go to Step 5.
YES (Code No. U0126 is set) : Replace steering wheel sensor (Refer to ), and then go to Step 5.
YES (Code No. U0141 is set) : Replace the ETACS-ECU (Refer to GROUP 54A - ETACS ), and then go to Step 5.
YES (Code No. U0317 is set) : Replace the electric parking brake ECU (Refer to GROUP 36 - Electric Parking Brake ECU ), and then go to Step 5.
YES (Code No. U1004 is set) : Replace the engine-ECU (Refer to GROUP 13A - Engine-ECU ), and then go to Step 5.
YES (Code No. U15A0 is set) : Replace the ACC/FCM-ECU (Refer to GROUP 17 - Adaptive Cruise Control System (ACC) ), and then go to Step 5.
YES (Code No. U15A5 is set) : Replace the FCM/LDW/AHB-ECU (Refer to GROUP 54A - FCM/LDW/AHB-ECU ), and then go to Step 5.
NO (No diagnosis code is set.) : The procedure is complete.
 
STEP 5. Check whether the diagnosis code is set again.
Erase the diagnosis code.
Is Code No. U0100, U0101, U0114, U0126, U0141, U0317, U1004, U15A0 or U15A5 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
The procedure is complete.
