Signal Circuit Inspection

Check voltage
1. IG "OFF" and disconnect CKPS connector.
2. IG "ON" and ENG "OFF"
3. Measure voltage between terminal 1 of CKPS harness connector and chassis ground.
4. Measure voltage between terminal 2 of CKPS harness connector and chassis ground.
  Specification: Approx. 1.4V
5. Is the measured voltage within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Go to " 2Check short in harness" as follows.
Check short in harness
1. IG "OFF" and disconnect CKPS connector and PCM connector.
2. Measure resistance between terminal 1 (2) of CKPS harness connector and chassis ground.
3. Measure resistance between terminals 1 and 2 of CKPS harness connector.
  Specification: Infinite
4. Is the measured resistance within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair short in harness, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
