45 Release valve can no longer be activated
Release valve 1Y4 can not be activated. --> window 5
Possible causes: open connection in cable loom to the release valve, release valve solenoid
defective
Truck responses: W – B
46 Release valve can no longer be deactivated
Release valve 1Y4 was activated, but can no longer be deactivated.
--> window 5
Possible causes: LHC module defective; cable loom for release valve is permanently "+"
Truck responses: W – B
47 Current of release valve is too low
Release valve 1Y4 can not be activated --> window 5
Possible causes: inherent resistance of solenoid of valve 1Y4 is too large or solenoid not
connected; cable loom
Truck responses: W – B
51 Current of solenoid for IC engine is too high
The vehicle detects too high a current value for solenoid iY1 to speed controller, over 1.8 A --
> window 6
Possible causes: short in solenoid iY1 or in cable loom to solenoid iY1
Truck responses: W – E – L – F – S
52 Current of solenoid for IC engine is too low
The vehicle detects too low a current value for solenoid iY1 to speed controller --> window 6
Possible causes: cable loom has an open connection to solenoid iY1, solenoid defective.
Truck responses: W – E – L – F – S
53 Current for pump forward solenoid is too high
Current value for proportional solenoid iY2 is too high. --> window 6
Causes: short in proportional solenoid iY2 or in cable loom to the solenoid
Truck responses: W – E – L – F – S
54 Current for pump forwards solenoid is too low
The vehicle detects too low a current value for proportional solenoid iY2
--> Window 6
Possible causes: cable loom has an open connection to solenoid iY2, proportional solenoid
defective
Truck responses: W – E – L – F – S
55 Current for pump reverse solenoid is too high
The current value for proportional solenoid iY3 is high --> window 6
Possible causes: short in proportional solenoid iY3 or in cable loom to the solenoid.
Truck responses: W – E – L – F –S
