1. Disconnect the occupant detection sensor connector.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Resistance:

   Tester Connection	Condition	Specified Condition
   A-1 - A-3	The passenger seat is occupied	Below 100 Ω
   A-1 - A-3	The passenger seat is not occupied	Below 1 MΩ

1. Disconnect the front seat inner belt RH connector.
   

2. Measure the resistance according to the value(s) in the table below.
