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. As a result, a DTC may be stored.
If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.
HINT:

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

PROCEDURE

1.	CHECK FOR DTCs

(a) Check for DTCs of SFI system.

(1) for M20A-FKS:

Powertrain > Engine > Trouble Codes

(2) for 2ZR-FAE:

Powertrain > Engine and ECT > Trouble Codes

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

GO TO SFI SYSTEM

2.	CHECK FOR DTCs (HEALTH CHECK)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

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

(e) Check for DTCs.

(f) Turn the ignition switch off.

OK:

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

HINT:

If the vehicle information stored in the forward recognition camera is different from the actual vehicle specifications, the vehicle information stored in the forward recognition camera may be incorrect. Replace the forward recognition camera.
If the vehicle information stored in the forward recognition camera matches the actual vehicle specifications, the installed ECM is incompatible. Replace the ECM.

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
