Signal Circuit Inspection
- Check short to ground in harness
- IG "OFF".
- Disconnect APS connector and ECM connector.
- Measure resistance between APS2 signal terminal of APS harness connector and chassis ground. (Measurement "A")
- Measure resistance between APS2 signal and APS2 ground terminals of APS harness connector. (Measurement "B")
Specification: Infinite
- Is the measured resistance 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
- IG "OFF" and disconnect APS connector and ECM connector.
- Measure resistance between APS2 signal terminal of APS harness connector and APS2 signal terminal of ECM harness connector.
Specification: Approx. below 1Ω.
- 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.
