Signal Circuit Inspection

Check Voltage
1. IG "OFF" and disconnect FLS connector.
2. IG "ON" & ENG "OFF"
3. Measure voltage between terminal 3 of FLS harness connector and chassis ground.
  Specification : Approx. 11.46V
4. Is the measured voltage within specification ?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Go to " 2Check short to ground in harness" as follows
Check short to ground in harness
1. IG "OFF" and disconnect FLS connector.
2. Measure resistance between terminal 3 of FLS harness connector and chassis ground.
  Specification : Infinite
3. Is the measured resistance within specification ?
  YES
  - Go to " 3Check open in harness" procedure.
  NO
  - Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check open in harness
1. IG "OFF" and disconnect FLS connector and PCM connector.
2. Measure resistance between terminal 3 of FLS harness connector and terminal 29 of PCM harness connector.
  Specification : Approx. Below 1Ω
3. Is the measured resistance within specification ?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
