4. Is the measured voltage within specification?

   YES 

   • Go to "Ground Circuit Inspection " procedure.

   NO 

   • Go to "Check open in harness" as follow.

■ Check open in harness 

1. IG "OFF" and disconnect OTS connector and PCM connector.
2. Measure resistance between signal terminal of OTS harness connector and OTS signal terminal of PCM harness connector.

   Specification:  Below 1 Ω.
