Code No.U0100 Engine CAN timeout
 
 
caution
  • If diagnosis code No.U0100 is set, be sure to diagnose the CAN bus line.
  • Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
 
 
TROUBLE JUDGEMENT
If signal from the Engine-ECU cannot be received for 2,500 ms or more, the camera-ECU sets diagnosis code No.U0100.
note"Thunder" mark is displayed on the vehicle icon when diagnosis code No.U0100 is set.
 
 
PROBABLE CAUSES
  • Malfunction of Engine-ECU
  • Malfunction of ETACS-ECU
  • Malfunction of camera-ECU
  • Malfunction of CAN bus
 
 
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 diagnosis code.
Check if diagnosis code No.U0141 is set in the camera-ECU.
Is the diagnosis code set?
Troubleshoot the diagnosis code No.U0141 (Refer to ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE other system diagnosis code.
Check if diagnosis code No.U0100 is set in the ASC-ECU.
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 camera-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 Engine-ECU (Refer to GROUP 13A - Engine-ECU ).
A poor connection, open circuit, or other intermittent malfunction in the CAN bus line between the camera-ECU and the Engine-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 camera-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 camera-ECU. (Refer to )
A poor connection, open circuit, or other intermittent malfunction in the CAN bus line between the camera-ECU and the Engine-ECU (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
