3. 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.
  NO
  - Substitute with a known-good TPS and check for proper operation. If the problem is corrected, replace TPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM. After testing ECM on the vehicle, use this function before reusing the ECM
    CAUTION:
    Procedure of ETS Initialization
    
    Erase the trouble codes on ECM
    
    Turn the ignition key off and keep this condition until the main relay is turned off. (10 sec.)
    
    Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
