Code No. C1707: Implausible Coding Data
 
 
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.
  • When diagnosis code No. C1707 is set in the AWC-ECU, a diagnosis code may also be set in the ETACS-ECU. When the diagnosis code is set in ETACS-ECU, perform the diagnosis of the diagnosis code for ETACS-ECU first.
 
 
OPERATION
AWC-ECU receives the vehicle information stored in ETACS-ECU via CAN bus lines.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code will be set when the vehicle information received from the ETACS-ECU is invalid.
 
 
PROBABLE CAUSES
  • Malfunction of ETACS-ECU
  • The ETACS-ECU, which was used on another vehicle, is installed on this vehicle.
  • The AWC-ECU, which was used on another vehicle, is installed on this vehicle.
  • Malfunction of AWC-ECU
  • Noise interference
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to perform the CAN bus diagnosis.
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 other system diagnosis code.
Check if the ETACS diagnosis code is set (Refer to GROUP 54A - Troubleshooting ).
Is the diagnosis code set?
Carry out the appropriate troubleshooting.
Go to Step 3.
 
STEP 3. ETACS-ECU coding data check
Use the M.U.T.-IIISE to check whether the coding data stored in the ETACS-ECU is correct.
Is the check result normal?
Go to Step 4.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
 
STEP 4. Check a part number of the ASC-ECU.
Check a part number of ASC-ECU.
Is the check result normal?
Go to Step 5.
Replace the AWC-ECU (Refer to ).
 
STEP 5. Check whether the diagnosis code is set again.
Is diagnosis code No.C1707 set?
Replace the AWC-ECU (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
