54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > COMBINATION METER > DIAGNOSIS CODE PROCEDURES > CODE No.U0100 TIME-OUT DURING CAN COMMUNICATION WITH ENGINE-ECU
Code No.U0100 Engine CAN timeout
 
 
caution
  • If diagnosis code No. U0100 is set, be sure to diagnose the CAN bus line.
  • Before replacing the ECU or combination meter, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
DIAGNOSTIC FUNCTION
The combination meter sets diagnosis code No.U0100 when it cannot receive signals from the engine-ECU.
 
 
JUDGEMENT CRITERIA
With the ignition switch is at ON position, diagnosis code No. U1190 is not set, if the communication with engine-ECU cannot be established for 5000 ms or more, the combination meter determines that a problem has occurred.
 
 
PROBABLE CAUSES
  • Malfunction of CAN bus line
  • Malfunction of engine-ECU
  • Malfunction of combination meter
 
 
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 if diagnosis code is set in the engine-ECU.
Is the diagnosis code set?
Troubleshoot the engine (Refer to GROUP 13A - Diagnosis Code Chart ).
Go to Step 3.
 
STEP 3. Check the M.U.T.-IIISE Diagnosis code for other systems.
Check if diagnosis code No. U0100 is set in the ETACS-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 combination meter.
(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.
A poor connection, open circuit, or other intermittent malfunction in the CAN bus line between the combination meter 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 combination meter.
(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 combination meter.
A poor connection, open circuit, or other intermittent malfunction in the CAN bus line between the combination meter and the engine-ECU (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
