Signal Circuit Inspection

1. IG "OFF".
2. Disconnect APS connector and ECM connector.
3. Measure resistance between APS2 signal terminal of APS harness connector and chassis ground (Measurement "A").
4. Measure resistance between APS2 signal and APS1 (2) ground terminals of APS harness connector (Measurement "B").

   Specification:  Infinite

5. Is the measured resistance within specification?

   YES 

   • Go to "CHECK 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 APS connector and ECM connector.
2. Measure resistance between APS2 signal terminal of APS harness connector and APS2 signal terminal of ECM 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.
