PROBLEM SYMPTOMS TABLE
NOTICE:
-
w/ Smart Key System:
Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
-
If the headlight ECU sub-assembly LH has been replaced, it is necessary to synchronize the vehicle information and initialize the headlight ECU sub-assembly LH.

- When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
-
w/ Automatic High Beam System:
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.
-
w/ Automatic High Beam System:
If the forward recognition camera has been replaced with a new one, be sure to perform Forward Recognition Camera Learning.
