DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid/Incompatible Software Component [12/2024 - ]: Procedure

1. Check for DTCs.

   Powertrain > Engine > Trouble Codes 

   HINT: 

   If DTC U0300-51 or U0300-57 is output, inspect the SFI system first as a SFI system DTC may be stored.

   Result

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

Result: 

B 

GO TO REFER TO "SFI SYSTEM" 

Result: 

A 

See step  2

1. Using the GTS, perform a health check.

   OK

   ECUs other than the forward recognition camera do not output specification information mismatch DTCs related to the ECM.

   Result

   Result	Proceed to
   DTC is not output	A
   DTC is output	B

Result: 

B 

REPLACE ECM 

Refer to REMOVAL [12/2024 - ]

Result: 

A 

See step  3

1. Using the GTS, read the Data List.

   HINT: 

   • When the specification stored by the forward recognition camera and the vehicle specification do not match, there is a malfunction in the specification information stored by the forward recognition camera. Therefore, replace the forward recognition camera.
   • When the specification stored by the forward recognition camera and the vehicle specification match, a ECM with different specifications may be installed. Therefore, replace the ECM.

   Result

   Result	Proceed to
   Vehicle information stored in the forward recognition camera and actual vehicle specifications do not match Default Value is displayed	A
   Vehicle specification information stored in forward recognition camera and actual vehicle specifications match	B

Result: 

A 

REPLACE FORWARD RECOGNITION CAMERA
