LIGHTING (INT) LIGHTING SYSTEM PROBLEM SYMPTOMS TABLE

NOTICE:: ·

Inspect the fuses and bulbs for circuits related to this system before performing the following procedure.

·

w/ Entry and Start System:

Before replacing the main body ECU (multiplex network body ECU) and certification ECU (smart key ECU assembly), refer to Service Bulletin.

HINT:: Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
