56 Current for pump reverse solenoid is too low
The vehicle detects too low a current value for proportional solenoid iY3
--> window 6
Possible causes: cable loom has an open connection to solenoid iY3, proportional solenoid
defective
Truck responses: W – E – L – F – S
57 Current for gas shutoff valve is too high
The current applied to gas shutoff valve solenoid 1Y5 is too high
Possible causes: short in/at gas shutoff valve solenoid 1Y5 or in the cable loom to the solenoid.
Truck response: W
58 Current for gas shutoff valve is too low
The vehicle detects too low a current value at the solenoid for gas shutoff valve 1Y5
Possible causes: cable loom has an open connection to solenoid 1Y5 of the gas shutoff valve or
in the solenoid
Truck response: W
59 Status of release valve
The controller can not detect if release valve 1Y4 ( solenoid ) is activated or not.
Possible causes: release valve 1Y4 defective, cable loom
Truck responses: W – B
61 Engine speed too high
This error code appears if the engine speed is over 3000 rpm for 10 seconds.
Possible causes: injection pump; proportional solenoid
Truck response: W
62 Sudden change in RPM signal from over 800 to 0 rpm
The vehicle no longer detects any engine speed, although the engine was not shut down with the
ignition key.
Possible causes: speed sensor 1B1 defective, cable loom to the speed sensor has an open
connection
Truck response: W
65 Tilt pressure signal of 6 bar without RPM
The controller senses an active (closed) pressure switch 1S1 although no engine RPM exists
--> window 4
Possible causes: pressure switch 1S1 defective, cable loom from pressure switch 1S1 is shorted
66 Lift pressure signal of 14 bar without RPM
The controller senses an activated (closed) pressure switch 1S2, although no engine RPM
exists. --> window 4
Possible causes: pressure switch 1S2 defective, cable loom from pressure switch 1S2 shorted
Truck response: W
