Dtc C1611 Ecu Malfunction

DESCRIPTION

INSPECTION PROCEDURE

READ VALUE USING GTS (PARKING ASSIST ECU STATUS)

SETTINGS (PARKING ASSIST ECU INITIALIZATION)

CHECK FOR DTC

DESCRIPTION

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.

INSPECTION PROCEDURE

NOTICE:

1. When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point (LandCruiser RM0000035DE05TX.html).
   
2. 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 (LandCruiser RM0000035DD06LX.html).
   

1. Use the Data List to check if the parking assist ECU status is functioning properly (LandCruiser RM000003WW005BX.html).
   
   

   Parking Assist Monitor System

   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 "NG" is displayed, there is a malfunctions in parking assist ECU.

   Result

   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

HINT:

1. 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.
   
2. 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 (LandCruiser RM000003WVZ06KX.html).
   

   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).

2. 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 (LandCruiser RM0000035DD06LX.html)
   Initialized	Back camera position setting (LandCruiser RM0000035DD06LX.html) Steering angle setting (LandCruiser RM0000035DD06LX.html) Side camera position setting (LandCruiser RM000003XM401ZX.html )

1. Clear the DTCs (LandCruiser RM0000035DB07DX.html).
   

2. Check for DTCs (LandCruiser RM0000035DB07DX.html).
   

   OK:

   DTC C1611 is not output.
   

HINT:

1. If DTC C1611 is output, perform the procedure to allow the parking assist ECU to store the vehicle information again.
   
2. 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.
   
3. If DTC C1611 is output frequently, replace the parking assist ECU even though the DTC is not output when rechecking for DTCs.
