Signal Circuit Inspection

Check voltage.
1. IG "OFF" and disconnect FTPS connector.
2. IG "ON" & ENG "OFF"
3. Measure voltage between terminal 1 of FTPS harness connector and chassis ground.
  Specification : Approx. 0V
4. Is the measured voltage within specification ?
  YES
  - Go to " 2Check open in harness" as follows.
  NO
  - Repair short to ground in harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check open in harness.
1. IG "OFF" and disconnect FTPS and PCM connector.
2. Measure resistance between terminal 1 of FTPS harness connector and terminal 28 of PCM harness connector.
  Specification : Approx. Below 1Ω
3. Is the measured resistance within specification ?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair open in harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
