PARKING ASSIST MONITOR SYSTEM, Diagnostic DTC:C1611

DTC Code DTC Name
C1611 ECU Malfunction

DESCRIPTION

This DTC is stored if the parking assist ECU judges that there is an internal malfunction as a result of its self check.

Tip:

The parking assist ECU stores different types of information during initialization. If the parking assist ECU cannot read the stored information when it is activated, the parking assist ECU judges that there is an internal malfunction and stores this DTC.

DTC No.

CAUTION / NOTICE / HINT

Note:

  • When "System initializing" is displayed on the display and navigation module display after the battery terminal disconnected, correct the steering angle neutral point (Click here).

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed (Click here).

PROCEDURE

  1. READ VALUE USING INTELLIGENT TESTER

    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Chassis / Parking Assist Monitor System / Data List.

  2. SETTINGS (PARKING ASSIST ECU INITIALIZATION)

    Tip:

    • The parking assist ECU stores different types of information during initialization. If the parking assist ECU cannot read the stored information when it is activated, the parking assist ECU judges that there is an internal malfunction and stores this DTC.

    • If the parking assist ECU cannot read the stored information when it is activated, allowing the ECU to store the information again may return the system to normal.

    1. Use the transition of diagnosis screens (note which transition pattern occurs) to confirm if the parking assist ECU was able to properly store the information from initialization.

      Tip:

      The procedure to make the parking assist ECU store the vehicle information differs when the parking assist ECU has stored the information (initialized) and when the information has not been stored (not initialized).

    2. Perform the following procedure depending on the memory conditions to register the vehicle information into the parking assist ECU.

  3. CHECK FOR DTC

    1. Clear the DTCs.

      Click here

      Chassis > IPA/Parking Assist Monitor > Clear DTCs

    2. Check for DTCs.

      Click here

      Chassis > IPA/Parking Assist Monitor > Trouble Codes

      Result

      Result

      Proceed to

      DTC C1611 is output

      A

      No DTC is output

      B
      Tip:

      • If DTC C1611 is output, perform the procedure to allow the parking assist ECU to store the vehicle information again.

      • If DTC C1611 is still output after performing the procedure to make the parking assist ECU store the vehicle information 3 times, replace the parking assist ECU.

      • If DTC C1611 is output frequently, replace the parking assist ECU even though the DTC is not output when rechecking for DTCs.
