SUGGESTED ACTION
DIAGNOSTIC FLASH CODE/ENGINE PERFORMANCE RELATIONSHIP–3100 HEUI VEHICLE ENGINE (DEUCE)
1—These diagnostic flash codes may affect the system only under specific environmental conditions, such as engine start-up at cold temperature, cold weather operation at
high altitude, etc.
Shutdown Machine: Drive the machine to a safe stopping area and get immediate service. Severe engine damage may result.
Service ASAP (As Soon As Possible): The operator should go to the nearest qualified service location.
Schedule Service: The operator should have the problem investigated when convenient.
