3. Is the measured resistance within specification?
  YES
  - Go to "OCV Actuation Test " as follows.
  NO
  - Substitute with a known - good OCV and check for proper operation. If the problem is corrected, replace OCV and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

  YES
  - Substitute with a known - good ECM and check for proper operation. If the problem is corrected, replace ECM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known - good OCV and check for proper operation. If the problem is corrected, replace OCV and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
