Signal Circuit Inspection

■ Check Voltage
1. IG "OFF"&ENG "OFF"
2. Disconnect OTS connector
3. IG "ON"&ENG "OFF"
4. Measure voltage between harness signal terminal of OTS and chassis ground.
  1. Specification: Approx. 5V

5. Is the measured voltage within specification?
  YES
  1. Go to "GROUND CIRCUIT INSPECTION " procedure.
  NO
  1. Go to "Check open in harness" as follow.
- ■ Check open in harness
  1. IG "OFF"& ENG "OFF"
  2. Disconnect OTS and PCM connector.
  3. Measure resistance between signal terminal of OTS harness connector and OTS signal terminal of PCM harness connector.
    1. Specification : Approx. below 1Ω
