Inspection Procedure

HINT:

Displays except for the seat belt warning indicator are shown in the navigation system (See PROBLEM SYMPTOMS TABLE ), supplemental restraint system (See PROBLEM SYMPTOMS TABLE ), and A/C system (See ON-VEHICLE INSPECTION ).
The passenger seat belt warning light can be inspected with it removed from the vehicle. The accessory meter assembly should be replaced if the passenger seat belt warning light has a malfunction because this part is not independently supplied.

PERFORM ACTIVE TEST BY INTELLIGENT TESTER

Operate the intelligent tester according to the steps on the display and select the "ACTIVE TEST".
