Signal Circuit Inspection

Check Voltage
1. IG "OFF" & ENG "OFF"
2. Disconnect OTS connector
3. IG "ON" & ENG "OFF"
4. Measure voltage between harness terminal 1 of OTS and chassis ground.
  Specification : Approx. 5V
5. Is the measured voltage within specification ?
  YES
  - Go to "GROUND CIRCUIT INSPECTION " procedure.
  NO
  - Go to " 2Check open in harness" as follow.
Check open in harness
1. IG "OFF" & ENG "OFF"
2. Disconnect OTS and PCM connector.
3. Measure resistance between terminal 1 of OTS harness connector and terminal 4 of PCM harness connector.
  Specification : Approx. below 1 Ω
4. Is the measured resistance within specification ?
  YES
  - Go to "GROUND CIRCUIT INSPECTION " procedure.
  NO
  - Repair or replace open in harness, and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
