DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid/Incompatible Software Component; DTC U0301-57: Software Incompatibility with ECM/PCM Invalid/Incompatible Software Component [01/2023 - ]: Procedure
- CHECK FOR DTCs (EV)
- Check for DTCs.
Powertrain > EV > Trouble Codes
HINT:
If DTC U0300-51, U0300-57 or U0301-57 is output, inspect the hybrid control system first as a hybrid control system DTC may be stored.
Result
Result Proceed to Hybrid control system DTC is not output A Hybrid control system DTC is output B
Result:
B
GO TO HYBRID CONTROL SYSTEM. Refer to DIAGNOSTIC TROUBLE CODE CHART [01/2023 - 11/2023] , or refer to DIAGNOSTIC TROUBLE CODE CHART [11/2023 - ]
Result:
A
See step 2
- Check for DTCs.
- CHECK FOR DTCs (HEALTH CHECK)
- 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 EV control ECU.
Result
Result Proceed to DTCs are not output A DTCs are output B
Result:
B
REPLACE EV CONTROL ECU. Refer to REMOVAL [01/2023 - ]
Result:
A
See step 3
- Using the GTS, perform a health check.
- READ VALUE USING GTS (Powertrain Information)
- Using the GTS, read the Data List.

Tester Display Measurement Item Range Normal Condition Diagnostic Note Powertrain Information Powertrain information Conventional, SS, HV, PHV, EV, 1MHV, FCV or Default Value Conventional: Conventional vehicle
SS: w/ Stop and start vehicle
HV: HEV
PHV: PHEV
EV: BEV
1MHV: 1MHV
FCV: FCEV
Default Value: Vehicle information not confirmed- Chassis > Front Recognition Camera > Data List
Tester Display Powertrain Information 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 EV control ECU with different specifications may be installed. Therefore, replace the EV control ECU.
Result
Result Proceed to - Vehicle information stored in the forward recognition camera and actual vehicle specifications do not match
- Not confirmed is displayed
A Vehicle specification information stored in forward recognition camera and actual vehicle specifications match B
Result:
A
REPLACE FORWARD RECOGNITION CAMERA. Refer to REMOVAL [01/2023 - ]
Result:
B
REPLACE EV CONTROL ECU. Refer to REMOVAL [01/2023 - ]
- Using the GTS, read the Data List.
