Code No. U0141 ETACS CAN timeout
 
 
caution
  • If the diagnosis code No. U0141 is set, diagnose the CAN bus lines.
  • When replacing the ECU, always check that the SRS circuit is normal.
 
 
FUNCTION
If the signal from ETACS-ECU cannot be received, the SRS-ECU sets the diagnosis code No. U0141.
 
 
TROUBLE JUDGEMENT
Because of the CAN-C bus circuit malfunction, if SRS-ECU becomes unable to perform the normal data transmission, SRS-ECU determines that an abnormality is present.
cautionIn order to record the diagnosis code even after diagnosis code recording is stopped, erase the past failure if there is the record of a past failure after implementing troubleshooting.
 
 
PROBABLE CAUSES
  • Malfunction of CAN bus line
  • Malfunction of SRS-ECU
  • Malfunction of the ETACS-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics
Use the M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 2.
Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE other system diagnosis code
Check again if the diagnosis code is set in the ETACS-ECU.
Is the diagnosis code set?
Diagnose the ETACS-ECU (Refer to GROUP 54A - ETACS, Troubleshooting ).
Go to Step 3.
 
STEP 3. Check the M.U.T.-IIISE Diagnosis code for other systems
Check if the diagnosis code No. U1109 is set to combination meter.
Is the diagnosis code set?
Go to Step 4
Go to Step 5
 
STEP 4. Diagnosis code recheck
Check again if the diagnosis code is set in the SRS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if the diagnosis code is set.
Is the diagnosis code set?
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS, ETACS-ECU ). After replacing the combination meter, carry out the CAN bus diagnostics.
A poor connection, open circuit or other intermittent malfunction in the CAN bus line between the ETACS-ECU and the SRS-ECU (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 5. Diagnosis code recheck
Check again if the diagnosis code is set in the SRS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if the diagnosis code is set.
Is the diagnosis code set?
Replace the SRS-ECU (Refer to ). After replacing the combination meter, carry out the CAN bus diagnostics.
A poor connection, open circuit or other intermittent malfunction in the CAN bus line between the SRS-ECU and the ETACS-ECU (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
