Component Inspection

Check OTS resistance

IG "OFF" and disconnect OTS connector.

Measure resistance between signal and ground terminals of OTS connector after checking out the temperature of EOTS with scantool. (Component Side)

Specification:

Is the measured resistance within specification?
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.
  NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by ECM. Before or after testing ECM on the vehicle, use this function to reuse the ECM on the others
NO
- Substitute with a known - good OTS and check for proper operation. If the problem is corrected, replace OTS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
