LIGHTING (EXT) LIGHTING SYSTEM(except NR Series Engine) PROBLEM SYMPTOMS TABLE

NOTICE:: ·

Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.*

·

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.

·

When replacing the combination meter assembly, update the ECU security key.
