TROUBLE DIAGNOSIS EC-679 [VG33E] C D E F G H I J K L M A EC *: The items are the same as those of 1st trip freeze frame data. DATA MONITOR MODE ×: Applicable CAL/LD VALUE [%] ● The calculated load value at the moment a malfunction is detected is displayed. COOLANT TEMP [ °C] or [ °F] ● The engine coolant temperature at the moment a malfunction is detected is displayed. S-FUEL TRM-B1 [%] ● “Short-term fuel trim” at the moment a malfunction is detected is displayed. ● The short-term fuel trim indicates dynamic or instantaneous feedback compensation to the base fuel S-FUEL TRM-B2 [%] L-FUEL TRM-B1 [%] ● “Long-term fuel trim” at the moment a malfunction is detected is displayed. ● The long-term fuel trim indicates much more gradual feedback compensation to the base fuel schedule L-FUEL TRM-B2 [%] ENGINE SPEED [rpm] ● The engine speed at the moment a malfunction is detected is displayed. VHCL SPEED [km/h] ● The vehicle speed at the moment a malfunction is detected is displayed. ABSOL TH·P/S [%] ● The throttle valve opening angle at the moment a malfunction is detected is displayed. B/FUEL SCHDL ● The base fuel schedule at the moment a malfunction is detected is displayed.
