Signal Circuit Inspection

■ Check voltage 

1. IG "OFF". Disconnect OTS connector.
2. IG "ON"
3. Measure voltage between signal terminal of OTS harness connector and chassis ground.

   Specification:  Approx. 3.3V

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". 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 1Ω

3. Is the measured resistance within specification?

   YES 

   • Go to "GROUND CIRCUIT INSPECTION " procedure.

   NO 

   • Repair open in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
