    YES 

    • Check open or short on the communication line between ECM and IPM. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR ".
    • If there is no something wrong, substitute with a known - good ECM and check for proper operation. If the problem is corrected, replace the unit and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
