|
|
Code No. U0114
- Wiring harness or connector failure of CAN bus line
- 4WD-ECU malfunction
- ABS-ECU malfunction
|
|
Code No. U0141
- Wiring harness or connector failure of CAN bus line
- ETACS-ECU malfunction
- ABS-ECU malfunction
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|
Q.
Is the check result normal?

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.
|
|
