Code No. U0141: ETACS CAN Timeout
 
 
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.
  • Whenever the ECU is replaced, ensure that the communication circuit is normal.
  • When diagnosis code No.U0141 is set in ACC/FCM-ECU, the diagnosis code may also be set in ETACS-ECU. When the diagnosis code is set in ETACS-ECU, perform the diagnosis of the diagnosis code for ETACS-ECU first.
  • When the ETACS-ECU of vehicles without KOS is replaced, the encrypted code of the ignition key needs to be registered to the ETACS-ECU. (If the encrypted code is not registered, the engine cannot be started. Register the encrypted code as described in GROUP 54A, Immobilizer System - How to Register Key ID .)
  • When the ACC/FCM-ECU is replaced, calibrate the radar (refer to ).
 
 
OPERATION
ACC/FCM-ECU communicates with the ETACS-ECU via the CAN bus lines.
 
 
DIAGNOSIS CODE SET CONDITION
Check Condition
  • Ignition switch is "ON" position.
Judgement Criterion
  • The signal sent from the ETACS-ECU cannot be received.
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus line
  • Malfunction of ETACS-ECU
  • Malfunction of ACC/FCM-ECU

 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to perform the CAN bus diagnosis.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting, Can Bus Diagnostics Table ).
 
STEP 2. Check the other system diagnosis code.
Check whether an ETACS "time-out" related diagnosis code is set in other ECUs (Refer to GROUP 54C - CAN-Related Diagnosis Code Table ).
Is diagnosis code set?
Go to Step 3.
Go to Step 4.
 
STEP 3. Check whether the diagnosis code is set again.
Is diagnosis code No.U0141 set?
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
It can be assumed that this malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunction ).
 
STEP 4. Check whether the diagnosis code is set again.
Is diagnosis code No.U0141 set?
Replace the ACC/FCM-ECU (Refer to ).
It can be assumed that this malfunction is intermittent (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunction ).
