4. 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 BPS and PCM connector.
2. Measure resistance between signal terminal of BPS harness connector and BPS signal terminal of PCM harness connector.
  Specification: Approx. below 1Ω.

3. Is the measured resistance within specification?
  YES
  - Substitute with a known - good BPS and check for proper operation. If the problem is corrected, replace BPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Repair open in harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
