6. Buckle the front passenger's seat belt. 



Measure the resistance between the No. 1 and No. 3 terminals of the front passenger's seat belt 
buckle switch 3P connector. There should be 0-1 ohms.  



Measure the resistance between the No. 2 and No. 3 terminals of the same connector. There 
should be an open circuit or at least 1 Mohms.

Are the resistances as specified?  

YES - Go to step 7. 

NO - Replace the front passenger's seat belt buckle assembly (see SEAT BELT BUCKLE ), then 
clear the DTC. 

7. Unbuckle the front passenger's seat belt. 



Measure the resistance between the No. 2 and No. 3 terminals of the front passenger's seat belt 
buckle switch 3P connector. There should be 0-1 ohms.
