Is the measured resistance within specification ?
YES
- Substitute with a known-good ECM/PCM and check for proper operation. If the problem is corrected, replace ECM/PCM and then 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/PCM.
Before or after testing ECM/PCM on the vehicle, use this function to reuse the ECM/PCM.

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