Signal Circuit Inspection

Check short to ground in harness
1. IG "OFF".
2. Disconnect APS & PCM connector.
3. Measure resistance between terminal 2 of APS harness connector and chassis ground.
4. Measure resistance between terminal 2 and 5 of APS harness connector.
5. Measure resistance between terminal 2 and 4 of APS harness connector.
  Specification: Infinite
6. Is the measured resistance within specification?
  YES
  - Go to " 2Check open in harness" as follows.
  NO
  - Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
