Code No. U1417: Wrong coding data received
 
 
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 CAN bus lines are normal.
 
 
DIAGNOSTIC FUNCTION
CVT-ECU checks that the coding information is normal.
 
 
JUDGEMENT CRITERIA
The ETACS-ECU coding information about whether the AWC-ECU is mounted or not is incorrect.
 
 
PROBABLE CAUSES
  • Malfunction of CAN bus line
  • ETACS-ECU coding information is abnormal
  • ETACS-ECU failure or improper assembly
  • Malfunction of CVT-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 lines (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE diagnosis code
Check if the ETACS-related diagnosis code is set.
Is the ETACS-related diagnosis code set?
Carry out the appropriate troubleshooting.
Go to Step 3.
 
STEP 3. ETACS-ECU coding data check
Using M.U.T.-IIISE, check if any abnormality is present in the coding data below which is stored in the ETACS-ECU.
Final drive
  • OK: Front Drive <2WD>
  • OK: 4WD FF Base <4WD>
Is the check result normal?
Go to Step 4.
Replace the ETACS-ECU.
 
STEP 4. Symptom recheck after erasing diagnosis code
Is the diagnosis code set?
Replace CVT-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
