1. Check for DTCs.

   Powertrain > Engine > Trouble Codes 

   Result

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

Result: 

B 

GO TO SFI SYSTEM. Refer to  DIAGNOSTIC TROUBLE CODE CHART [09/2021 - 11/2022] 

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 ECM.

   Result

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

Result: 

B 

REPLACE ECM. Refer to  REMOVAL [09/2021 - 11/2022] 

Result: 

A 

See step  3

1. Using the GTS, read the Data List.

   Chassis > Front Recognition Camera > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   HV/EV Equipped Information	Vehicle information (engine) stored by forward recognition camera	Non-HV/EV or HV/EV	Non-HV/EV: Gasoline Model HV/EV: HV Model	If a display different from vehicle specification is output, a forward recognition camera that was used with a different vehicle was installed, or the forward recognition camera may be malfunctioning.

   Chassis > Front Recognition Camera > Data List 

   Tester Display
   HV/EV Equipped 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 ECM with different specifications may be installed. Therefore, replace the ECM.

   Result

   Result	Proceed to
   Specification stored by the forward recognition camera and vehicle specification do not match	A
   Specification stored by the forward recognition camera and vehicle specification match	B

Result: 

A 

REPLACE FORWARD RECOGNITION CAMERA. Refer to  REMOVAL [09/2021 - 11/2022] 

Result: 

B 

REPLACE ECM. Refer to  REMOVAL [09/2021 - 11/2022]
