Causes and troubleshooting
ignition box 2 indicates misfire – check gas flow and burner ignition 2 (X74, X77, I2)
ignition box 3 indicates misfire – check gas flow and burner ignition 3 (X75, X78, I3)
short circuit to ground or battery or no connection detected – check wiring and
relay (X72, K6, WH 272, BN 334)
short circuit to ground or battery or no connection detected – check wiring and
relay (X69, K3, WH 269, BN 331)
internal temperature of the electronic control unit is above 80 degree Celsius
diesel engine requests an air filter service
Not used
Not used
short circuit to ground or battery or no connection detected – check wiring (A9:20,
X1.1.4, S20)
Engine temperature is too high – let engine run in low idle and open the engine
cover
Check power supply for regulator or change it
Check charging system or change generator
Change or charge battery
Check wiring and connectors (A9:35, A9:18, S23)
Engine oil is too hot – engine ECU reduce RPM to idle or switch off the engine –
open engine cover and clean air filters and checked oil level
Engine speed is high
Engine speed is too high
Engine ECU has defect.
Check wiring and speed sensor (A9:1, A9:2 and shield)
Check CAN communication (A9:47,A9:48, X9:3, X9:4, X50, X51, X52, X53, X55,
X34:62, X34:63, A2:162, A2:163)
Not used
Check CAN communication (A9:47,A9:48, X9:3, X9:4, X50, X51, X52, X53, X55,
X34:62, X34:63, A2:162, A2:163)
