Code No. U1417 Variant coding value invalid (includes faulty installation)


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, Trouble code diagnosis ).
  • If diagnosis code No.U1417 is set in ASC-ECU, always diagnose the CAN bus lines. 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.U1417 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.
  • When the hydraulic unit (integrated with ASC-ECU) is replaced, always carry out the calibration of the steering wheel sensor, the G and yaw rate sensor and brake fluid pressure sensor (Refer to , and ).

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 is set when the vehicle information received from the ETACS-ECU is invalid.

PROBABLE CAUSES

  • Malfunction of ETACS-ECU
  • Engine ECU malfunction
  • ETACS-ECUs have been interchanged between two vehicles.
  • ASC-ECU malfunction
  • External noise interference
  • ASC-ECUs have been interchanged between two vehicles.

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnosis
Use M.U.T.-III to diagnose the CAN bus lines.

Q. Is the check result normal?
Go to Step 3.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnosis table ). On completion, go to Step 2.

STEP 2. Diagnosis code recheck after resetting CAN bus lines

Q. Is diagnosis code No.U1417 set?
Go to Step 3.
This diagnosis is complete.

STEP 3. M.U.T.-III other system diagnosis code
Use M.U.T.-III to check whether the ETACS-ECU-related or engine ECU-related diagnosis code is set or not.

Q. Is the diagnosis code set?
Troubleshoot for the relevant diagnosis code.
Go to Step 4.

STEP 4. ETACS-ECU coding data check
Refer to GROUP 00 - Coding List .

Q. Is the check result normal?
Go to Step 5.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ), and then go to Step 7.

STEP 5. Engine ECU coding data check
Refer to GROUP 00 - Coding List .

Q. Is the check result normal?
Go to Step 6.
NO (2000) : Replace the engine ECU (Refer to GROUP 13A - engine ECU ), and then go to Step 7.
NO (2200) : Replace the engine ECU (Refer to GROUP 13E - engine ECU ), and then go to Step 7.
NO (2400) : Replace the engine ECU (Refer to GROUP 13D - engine ECU ), and then go to Step 7.
NO (3000) : Replace the engine ECU (Refer to GROUP 13C - engine ECU ), and then go to Step 7.

STEP 6. Check part number of ETACS-ECU
Check the part number of ETACS-ECU.

Q. Is the check result normal?
Go to Step 7.
Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ), and then go to Step 7.

STEP 7. Check part number of ASC-ECU
Check the part number of ASC-ECU.

Q. Is the check result normal?
Go to Step 8.
Replace the ASC-ECU (Refer to ), and then go to Step 9.

STEP 8. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.U1417 set?
Replace the ASC-ECU (Refer to ), and then go to Step 9.
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).

STEP 9. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.U1417 set?
Return to Step 1.
This diagnosis is complete.
