|
This diagnosis code is set if ASC-ECU cannot receive the signal sent from other ECU for
a certain period.
|
|
ASC-ECU communicates with the engine-ECU, CVT-ECU, 4WD-ECU, steering wheel sensor, ETACS-ECU,
AS&G-ECU and ACC/FCM-ECU via the CAN bus lines.
|
|

|
|
Code No. U0101
- Wiring harness or connector failure of CAN bus line
- CVT-ECU malfunction
- ASC-ECU malfunction
|
|
Code No. U0114
- Wiring harness or connector failure of CAN bus line
- 4WD-ECU malfunction
- ASC-ECU malfunction
|
|
Code No. U0126
- Wiring harness or connector failure of CAN bus line
- Steering wheel sensor malfunction
- ASC-ECU malfunction
|
|
Code No. U0141
- Wiring harness or connector failure of CAN bus line
- Malfunction of ETACS-ECU
- ASC-ECU malfunction
|
|
Code No. U1004
- Wiring harness or connector failure of CAN bus line
- Malfunction of AS&G-ECU
- ASC-ECU malfunction
|
|
Code No. U15A0
- Wiring harness or connector failure of CAN bus line
- Malfunction of ACC/FCM-ECU
- ASC-ECU malfunction
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|
Q.
Is the check result normal?
|
|
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
On completion, go to Step 4.
|
|
|
|
Q.
Is Code No. U0100, U0101, U0114, U0126, U0141, U1004 or U15A0 set?
|
|
The procedure is complete.
|
|
|
|
Use M.U.T.-III to check that other diagnosis code is set in the ECU corresponding to the
relevant diagnosis.
|
|
Q.
Is other diagnosis code set?
|
|
Troubleshoot for the relevant diagnosis code.
|
|
|
|
Use M.U.T.-III to check if the same diagnosis code (time-out) is set in the other ECU.
|
|
Q.
Is any diagnosis code set?
|
|
YES (Code No. U0100 is set) : Replace the engine-ECU(Refer to GROUP 13A - Engine-ECU <4B1>,
GROUP 13C - Engine-ECU <4J1>, GROUP 13D - Engine-ECU <4N1>),
and then go to Step 5.
|
|
|
|
YES (Code No. U0101 is set) : Replace the CVT-ECU, and then go to Step 5.
|
|
|
|
YES (Code No. U0114 is set) : Replace 4WD-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. U1004 is set) : Replace the AS&G-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.
|
|
|
|
NO (No diagnosis code is set.) : The procedure is complete.
|
|
|
|
Erase the diagnosis code.
|
|
Q.
Is Code No. U0100, U0101, U0114, U0126, U0141, U1004 or U15A0 set?
|
|
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
|
|
|
|
The procedure is complete.
