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 (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
  • Whenever ECU is replaced, ensure that the CAN bus lines are normal.
  • When diagnosis code No.C1707 is set in ASC-ECU, the diagnosis code may also be set in ETACS-ECU. When the diagnosis code is set in ETACS-ECU, carry out the diagnosis of the diagnosis code for ETACS-ECU first.
 
 
OPERATION
ASC-ECU receives the vehicle information stored in the ETACS-ECU via CAN bus lines.
 
 
 
DIAGNOSIS CODE SET CONDITIONS
When received invalid coding data from the ETACS-ECU, this diagnosis code is set.
 
 
 
PROBABLE CAUSES
  • Malfunction of ETACS-ECU
  • ETACS-ECUs have been interchanged between two vehicles.
  • ASC-ECU malfunction
  • ASC-ECUs have been interchanged between two vehicles.
  • Malfunction of ETACS-ECU coding data
  • Engine-ECU malfunction
 
 
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 3.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ). On completion, go to Step 2.
 
STEP 2. Diagnosis code recheck after resetting CAN bus lines
Is diagnosis code No.C1707 set?
Go to Step 3.
This diagnosis is complete.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
Use M.U.T.-IIISE to check whether any coding-related diagnosis code is set by ETACS-ECU or engine-ECU.
Is the diagnosis code set?
Troubleshoot for the relevant diagnosis code.
Go to Step 4.
 
STEP 4. Check part number of ASC-ECU
Check the part number of ASC-ECU.
Is the check result normal?
Go to Step 5.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 5. ETACS-ECU coding data check
Is the check result normal?
Go to Step 6.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
 
STEP 6. Check part number of ETACS-ECU
Check the part number of ETACS-ECU.
Is the check result normal?
Go to Step 7.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
 
STEP 7. Engine-ECU coding data check
Is the check result normal?
Go to Step 8.
Replace the engine-ECU (Refer to GROUP 13A - Engine-ECU ).
 
STEP 8. Check whether the diagnosis code is set again.
Erase the diagnosis code.
Is diagnosis code No.C1707 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How to Cope with Intermittent Malfunctions ).
