Is the resistance as specified?  

YES - Go to step 14. 

NO - Short to ground in the driver's seat wire harness, left side wire harness, or MICU. Replace the 
faulty harness or part. 

14. Disconnect the driver's seat belt tension reducer solenoid 2P connector (see TEST ). Measure the 

resistance between the No. 1 terminal of the driver's seat wire harness 3P connector and body ground. 
There should be an open circuit or at least 1Mohms.

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 1Mohms.

Is the resistance as specified?  

YES - Go to step 9. 

NO - Open in the front passenger's seat wire harness or right side wire harness, or poor ground 
connection at G651 (see RIGHT SIDE WIRE HARNESS (FRONT BRANCH) ). If G651 is OK, 
replace the faulty harness. 

9. Disconnect the negative cable from the battery, then wait for 3 minutes.  

10. Disconnect both seat belt tensioner 4P connectors from the left side wire harness and right side wire 

harness (see step 6 ).  

11. Disconnect SRS unit connector B (28P) from the SRS unit (see step 7 ).  

12. Measure the resistance between the No. 16 terminal of SRS unit connector B (28P) and the No. 1 

terminal of the front passenger's seat wire harness 3P connector. There should be 0-1 ohms.
