Signal Circuit Inspection

Check for open in signal circuit.
1. Ignition "OFF"
2. Measure resistance between terminals 2 of the OTS harness connector and 52 of the PCM harness connector.
  Specification: Approx. 0ohm
3. Is resistance within specification?
  YES:
  - Go to next step below.
  NO:
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for short to battery in signal circuit.
1. Disconnected PCM connector.
2. Ignition "ON" & Engine "OFF".
3. Measure voltage between terminals 2 of the OTS harness connector and 52 of the PCM harness connector.
  Specification: Approx. 0V
4. Is voltage within specification?
  YES:
  - Go to "TERMINAL AND CONNECTOR INSPECTION " procedure.
  NO:
  - Repair short to battery in harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
