Code No.C2206 Re-execution of Variant Coding
 
 
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 ).
  • If diagnosis code No.C2206 is set in ASC-ECU, always diagnose the CAN bus line. If there is any fault in the CAN bus lines, an incorrect diagnosis code may be set. In this case, the set diagnosis code is not highly reliable.
  • Before replacing the ECU, ensure that the communication circuit is normal.
  • When diagnosis code No.C2206 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 set in the ETACS-ECU via CAN bus lines.
 
 
 
DIAGNOSIS CODE SET CONDITIONS
ASC-ECU communicates with ETACS-ECU via CAN bus lines. This diagnosis code is set if the vehicle information stored in ETACS-ECU varies from the one stored when the ignition switch was last turned on.
 
 
 
PROBABLE CAUSES
  • ETACS-ECU or ASC-ECU which was equipped with other vehicle is used.
  • Malfunction of ETACS-ECU
  • ASC-ECU malfunction
  • External noise interference
 
 
 
 
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 2.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
 
STEP 2. M.U.T.-IIISE Diagnosis code of other system
Use M.U.T.-IIISE to check that the vehicles information-related diagnosis code is set in the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU/Diagnosis code chart ).
Is the diagnosis code set?
Troubleshoot the relevant diagnosis code, and then go to Step 3.
Go to Step 5.
 
STEP 3. ETACS-ECU coding data check
Refer to GROUP 00 - Precautions before Service/Coding List.
Is the check result normal?
Go to Step 5.
Go to Step 4.
 
STEP 4. ETACS-ECU variant coding
Perform the variant coding to the ETACS-ECU.
Does variant coding succeed?
Go to Step 5.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ).
 
STEP 5. Check whether the diagnosis code is set again.
(1) Erase the diagnosis code.
(2) Ignition switch "LOCK" (OFF)
(3) Ignition switch "ON"
Is diagnosis code No.C2206 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
This diagnosis is complete.
