J1939 FMI
196 Coolant level sensor 1 circuit - Voltage below
111 normal, or shorted to low source. Low signal
4 voltage detected at engine coolant level circuit.
197 Coolant level - Data valid but below normal
111 operational range - Moderately severe level.
18 Low coolant level has been detected.
Barometric pressure sensor circuit - Voltage
221
above normal, or shorted to high source. High
108
signal voltage detected at barometric pressure
3
circuit.
Barometric pressure sensor circuit - Voltage
222
below normal, or shorted to low source. Low
108
signal voltage detected at barometric pressure
4
circuit.
227 Sensor supply 2 circuit - Voltage above normal,
3510 or shor ted to high source. High voltage
3 detected at sensor supply number 2 circuit.
Engine crankshaft speed/position - Data valid
234
but above normal operational range - Most
190
severe level. Engine speed signal indicates
0
engine speed above engine protection limit.
Sensor supply 3 circuit - Voltage below normal,
238
or shorted to low source. Low voltage detected
3511
on the +5 volt sensor supply circuit to the
4
engine speed sensor.
Sensor supply 3 circuit - Voltage above normal
239
or shor ted to high source. High voltage
3511
detected on the 5 volt sensor supply circuit to
3
the engine speed sensor.
Wheel-based vehicle speed - Data erratic,
241
intermittent, or incorrect. The ECM lost the
84
vehicle speed signal or is reading an erratic
2
value.
Fan control circuit - Voltage below normal, or
245
shorted to low source. Low signal voltage
647
detected at the fan control circuit when
4
commanded on.
Ambient air temperature sensor 1 circuit -
249
Voltage above normal or shorted to high
171
source. High signal voltage detected at ambient
3
air temperature circuit.
Ambient air temperature sensor 1 circuit -
256
Voltage below normal or shorted to low source.
