  4. Does the resistance of FLS change as lifting up and down the fuel level float?

    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.
      NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM.
      Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

    NO 

    • Substitute with a known - good Fuel Level Sender and check for proper operation. If the problem is corrected, replace Fuel Level Sender and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE: * Procedure of ETS Initialization
    1. Erase the trouble codes on PCM
    2. Turn the ignition key off and keep this condition until the main relay is turned off. ( It will takes 10sec.)
    3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
