DTC 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.
- HINT:
- 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 Code | DTC Detection Condition | Trouble Area |
| C1611 | EEPROM Status (Initial read) AISIC Output Status | Parking assist ECU initialization (not initialized parking assist ECU) Back camera position setting (initialized parking assist ECU) Side camera position setting (initialized parking assist ECU) Steering Angle setting (initialized parking assist ECU) Parking assist ECU |
INSPECTION PROCEDURE
- NOTICE:
When "System initializing" is displayed on the parking assist ECU after the battery terminal disconnected, correct the steering angle neutral point ().
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 (w/ Side Monitor System) may be needed ().
| 1.READ VALUE USING INTELLIGENT TESTER (PARKING ASSIST ECU STATUS) |
Use the Data List to check if the parking assist ECU status is functioning properly ().
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| EEPROM Status (Initial read) | Parking assist ECU information / OK or NG | OK: Parking assist ECU is normal NG: Parking assist ECU is abnormal | - |
| AISIC Output Status | Output condition of camera display signal / OK or NG | OK: Output condition of camera display signal is normal NG: Output condition of camera display signal is abnormal | If displayed "NG", There is a malfunctions in parking assist ECU. |
| Result | Proceed to |
| OK is displayed for both items. | A |
| NG is displayed for EEPROM Status (Initial read). | A |
| NG is displayed for AISIC Output Status | B |

| 2.SETTINGS (PARKING ASSIST ECU INITIALIZATION) |
- HINT:
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.
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 ().
- HINT:
- 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).
Perform the following procedure depending on the memory conditions to register the vehicle information into the parking assist ECU.
| Condition | Procedure |
| Not initialized | Parking assist ECU initialization () |
| Initialized | Back camera position setting () Steering angle setting () Side camera position setting ( ) |
| NEXT | |
| 3.CHECK FOR DTC |
Clear the DTCs ().
Check for DTCs ().
- OK:
- DTC C1611 is not output.
- HINT:
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.
