DTC

U030057

Internal Control Module Software Incompatibility Invalid / Incompatible Software Component

DESCRIPTION

The forward recognition camera receives vehicle information from the ECM via CAN communication.

If the vehicle information stored in the forward recognition camera differs from that sent from the ECM, the forward recognition camera stores this DTC.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
U030057	Internal Control Module Software Incompatibility Invalid / Incompatible Software Component	When the engine switch is on (IG) for 3 seconds or more, the vehicle information sent from the ECM does not match that stored in the forward recognition camera for 1 second or more.	SFI system Forward recognition camera ECM

CAUTION / NOTICE / HINT

NOTICE:

When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle and a DTC may be stored.
If the forward recognition camera has been replaced with a new one, forward recognition camera adjustment must be performed.
HINT:

Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.

PROCEDURE

1.	CHECK FOR DTCs

(a) Using the Techstream, check for SFI system DTCs.

Powertrain > Engine > Trouble Codes

Result	Proceed to
SFI system DTCs are not output	A
SFI system DTCs are output	B

GO TO SFI SYSTEM

2.	CHECK FOR DTCs (HEALTH CHECK)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(d) Enter the following menus: System Select / Health Check.

(e) Check DTCs.

(f) Turn the engine switch off.

OK:

DTCs indicating a vehicle information mismatch with the ECM are not output by any ECU other than the forward recognition camera.

Result	Proceed to
DTCs are not output	A
DTCs are output	B

REPLACE ECM

3.	READ VALUE USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(d) Enter the following menus: Body Electrical / Pre-Collision System / Data List.

(e) Read the Data List according to the display on the Techstream.

HINT:

If the vehicle information stored in the forward recognition camera is different than the actual vehicle specifications, the vehicle information stored in the forward recognition camera may be incorrect. Check for DTCs and replace the forward recognition camera if necessary.
If the vehicle information stored in the forward recognition camera matches the actual vehicle specifications, the installed ECM is incompatible. Replace the ECM with a correct one.

Result	Proceed to
Vehicle information stored in forward recognition camera and actual vehicle specifications do not match	A
Vehicle information stored in forward recognition camera and actual vehicle specifications match	B
