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 the diagnosis code U1195 or U1197 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
ASC-ECU communicates with ETACS-ECU via CAN bus lines.
This diagnosis code No.U1195 is set when the variant coding for ETACS-ECU has not been implemented.
This diagnosis code No.U1197 is set when there is difference between the vehicle information from the ETACS-ECU and the vehicle information stored in the ASC-ECU.
 
 
 
PROBABLE CAUSES
Code No.C1195 is set
  • Variant coding for ETACS-ECU has not been implemented.
  • ASC-ECU malfunction
Code No.C1197 is set
  • Malfunction of ETACS-ECU
  • ETACS-ECU have been interchanged between two vehicles.
  • ASC-ECU malfunction
  • External noise interference
  • ASC-ECU have been interchanged between two vehicles.
 
 
 
 
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. U1195 or U1197 set?
Go to Step 3.
The procedure is complete.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
Use M.U.T.-IIISE to check whether the ETACS-ECU-related or engine ECU-related diagnosis code is set or not (Refer to GROUP 13A - Diagnosis code chart , GROUP 54A - ETACS/Diagnosis code chart ).
Is any diagnosis code set?
Troubleshoot for the relevant diagnosis code.
Go to Step 4.
 
STEP 4. Check ETACS coding data
Is the check result normal?
Go to Step 6.
Go to Step 5.
 
STEP 5. ETACS-ECU variant coding
Perform the variant coding to the ETACS-ECU.
Does variant coding succeed?
Go to Step 7.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 6. Check part number of ASC-ECU
Check the part number of ASC-ECU.
Is the check result normal?
Go to Step 7.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 7. Check whether the diagnosis code is set again.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to the "OFF" position.
(3) Turn the ignition switch to the "ON" position.
(4) Turn the ignition switch to the "OFF" position.
(5) Turn the ignition switch to the "ON" position.
(6) Check that the ABS warning lamp goes out.
Is diagnosis code No.U1195 or U1197 set?
Replace the hydraulic unit (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 ).
