54=LOW FUEL (0-59)
0-18=short (0-20max.)
OIL Displays the code (0-250) for the oil pressure switch input to the HEC. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6 psi)
will display a value between 000 and 176. A low oil pressure or an inoperative engine oil pressure switch (less than 6 psi) will display a value greater than 176.
dEGC Display of engine temperature in Degrees C input from cylinder head temperature sensor.
49 C="C" mark
60 C=Normal band start
120 C=Normal band end
-40 C=No SCP message for 5 seconds
bAtt Displays the code (0-255) for the battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.
93-102=6.9-9.1 volts (Low voltage)
