Code No.U1197: Coding data unavailable
 
 
caution
  • If diagnosis code No. U1197 is set, diagnose the CAN bus lines.
  • When replacing the ECU, always check that the communication circuit is normal.
 
 
TROUBLE JUDGEMENT
This diagnosis code will be set when the variant coding for the ETACS-ECU has not been implemented.
 
 
PROBABLE CAUSES
  • Variant coding not performed
  • Malfunction of ETACS-ECU
  • Malfunction of multivision display
  • 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 other system diagnosis code.
Check if diagnosis code is set in the ETACS-ECU.
Is the diagnosis code set?
Diagnose the ETACS.
Go to Step 3.
 
STEP 3. ETACS-ECU coding data check.
Using M.U.T.-IIISE, check if any abnormality is present to the coding data which are stored in the ETACS-ECU.
Is the check result normal?
Go to Step 4.
Replace the ETACS-ECU.
 
STEP 4. Diagnosis code recheck.
Check again if the diagnosis code is set in the multivision display.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) Check if the diagnosis code is set.
Is the diagnosis code set?
Replace the multivision display (Refer to ).
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
