Is the measured resistance of FTS within specifications?
YES
- Substitute with a known-good PCM and check for proper operation.
  If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good FTS and check for proper operation.
  If the problem is corrected, replace FTS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
