DTC U1195: Coding not Completed
 
 
caution
  • If there is any problem in the CAN bus lines, an incorrect DTC may be stored. Prior to this diagnosis, diagnose the CAN bus lines.
  • Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
  • When the DTC No.U1195 stored in AWC-ECU, the DTC may also be stored in ETACS-ECU. When the DTC is stored in ETACS-ECU, perform the diagnosis of the DTC for ETACS-ECU first.
 
 
OPERATION
AWC-ECU receives the vehicle information stored in ETACS-ECU via CAN bus lines.
 
 
DTC SET CONDITION
This DTC is stored when the abnormality below is detected:
  • Coding has not been performed.
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus line
  • Coding not implemented
  • Malfunction of ETACS-ECU
  • Malfunction of AWC-ECU
 
 
DIAGNOSTIC PROCEDURE
STEP 1. Scan tool (M.U.T.-III) CAN bus diagnostics.
Use scan tool (M.U.T.-III) to perform the CAN bus diagnosis.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Diagnosis, Can Bus Diagnostics Table ).
 
STEP 2. Scan tool (M.U.T.-III) other system DTC.
Check the ETACS DTC (Refer to GROUP 54A - Diagnosis, Diagnostic Trouble Code Chart ).
Is the DTC stored?
Perform the relevant troubleshooting.
Go to Step 3.
 
STEP 3. ETACS-ECU coding data check
Using the scan tool (M.U.T.-III), check if there is the engine-related, transaxle-related, ASC-related abnormality to the coding data stored in the ETACS-ECU (Refer to GROUP 00 - Coding List ).
Is the check result normal?
Go to Step 4.
Replace the ETACS-ECU. Then go to Step 5.
 
STEP 4. Check whether the DTC is stored again.
Is DTC No.U1195 stored?
Replace the AWC-ECU (Refer to ). Then go to Step 5.
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
 
STEP 5. Check whether the DTC is stored again.
Is DTC No.U1195 stored?
Return to Step 1.
This diagnosis is complete.
