  4. Test the seat belt switch - right signal circuit for an open or high resistance.
Did you find and correct the condition?		 Go to Step 10  Go to Step 8 
8 Test the seat belt switch - right ground circuit for an open or high resistance.
Did you find and correct the condition?		 Go to Step 10  Go to Step 9 
9 Replace the seat belt switch - right. Refer to Seat Belt Buckle Replacement - Front .
Did you complete the replacement?		 Go to Step 10  -
