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 PROBLEM SYMPTOMS TABLE ).
• 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.

1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER 
   1. Operate the intelligent tester according to the steps on the display and select the "ACTIVE TEST".

      DATA LIST / AIR CONDITIONER:

      P-BELT REMIND	Indicat. Light P-SEAT BELT (OFF / ON)	Confirm that the vehicle is stopped, engine idling

   OK: 

   Indicator light (ON / OFF) can be switched by ACTIVE TEST. 

   OK: Go to step  5

   NG: GO TO NEXT STEP 

2. CHECK HARNESS AND CONNECTOR (BETWEEN PASSENGER SEAT BELT WARNING LIGHT AND COMBINATION ME) 
   1. Disconnect the E2 and E11 connectors.
   2. Measure the resistance to the value(s) in the table blow.
