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 [12/2022 - 03/2023]: Procedure

1. Check for DTCs.

   Powertrain > Hybrid Control > 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 

for M20A-FXS: Refer to DIAGNOSTIC TROUBLE CODE CHART [12/2022 - ]

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 hybrid vehicle control ECU.

   Result

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

Result: 

B 

REPLACE HYBRID VEHICLE CONTROL ECU. Refer to  REMOVAL [12/2022 - 03/2023] 

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 hybrid vehicle control ECU with different specifications may be installed. Therefore, replace the hybrid vehicle 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 [12/2022 - 03/2023] 

Result: 

B 

REPLACE HYBRID VEHICLE CONTROL ECU. Refer to  REMOVAL [12/2022 - 03/2023]
