侍# Some fault codes are not applied to this machine. 3-24 Fault code J1939 SPN J1939 FMI Reason Effect (only when fault code is active) 196 111 4 Coolant level sensor 1 circuit - Voltage below normal, or shorted to low source. Low signal voltage detected at engine coolant level circuit. None on performance. 197 111 18 Coolant level - Data valid but below normal operational range - Moderately severe level. Low coolant level has been detected. Engine power derate. 221 108 3 Barometric pressure sensor circuit - Voltage above normal, or shorted to high source. High signal voltage detected at barometric pressure circuit. Engine power derate.
222 108 4 Barometric pressure sensor circuit - Voltage below normal, or shorted to low source. Low signal voltage detected at barometric pressure circuit. Engine power derate. 227 3510 3 Sensor supply 2 circuit - Voltage above normal, or shorted to high source. High voltage detected at sensor supply number 2 circuit. Engine power derate. 234 190 0 Engine crankshaft speed/position - Data valid but above normal operational range - Most severe level. Engine speed signal indicates engine speed above engine protection limit. Engine power derate. 238 3511 4 Sensor supply 3 circuit - Voltage below normal, or shorted to low source.
Low voltage detected on the +5 volt sensor supply circuit to the engine speed sensor. Engine may run rough, may stop running, may not start, or may be difficult to start. 239 3511 3 Sensor supply 3 circuit - Voltage above normal or shorted to high source. High voltage detected on the 5 volt sensor supply circuit to the engine speed sensor. Engine may run rough, may stop running, may not start, or may be difficult to start. 241 84 2 Wheel-based vehicle speed - Data erratic, intermittent, or incorrect. The ECM lost the vehicle speed signal or is reading an erratic value. Engine speed limited to ,maximum engine speed without VSS parameter value.
Cruise control, gear-down protection, and road speed governor will not work. 245 647 4 Fan control circuit - Voltage below normal, or shorted to low source. Low signal voltage detected at the fan control circuit when commanded on. The fan may stay on continuously or not run at all. 249 171 3 Ambient air temperature sensor 1 circuit - Voltage above normal or shorted to high source. High signal voltage detected at ambient air temperature circuit. Possible reduced engine performance. 256 171 4 Ambient air temperature sensor 1 circuit - Voltage below normal or shorted to low source. Low voltage detected at ambient air temperature circuit. Possible reduced engine performance.
271 1347 4 Fuel pump pressurizing assembly 1 circuit - Voltage below normal, or shorted to low source. Low signal voltage detected at the fuel pump actuator circuit. Engine power derate.
