Signal Circuit Inspection

Check the signal circuit for short to battery
1. Disconnect PCM harness connector
2. Ignition "ON" & Engine "OFF"
3. Measure voltage between signal terminal 2 of OTS harness connector and chassis ground
  Specification : Approx. 0 V
4. Is voltage within specification?
  YES
  - Go to next step as below.
  NO
  - Check for short to battery in signal circuit. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check the signal circuit for open
1. Ignition "OFF"
2. Measure resistance between signal terminal 2 of OTS harness connector and OTS signal terminal 40 of PCM harness connector.
3. Is voltage within the specification?
  YES
  - Go to next step as below.
