Rectification
Check CAN Bus and Bus connection
[ch. 5.1].
(1
Internal fault
Check housing temperature (max. 60°C), if
necessary supply with cooling air.
Check mechanics after the actuator for
freedom of movement.
Check rotation direction, change if re-
quired (OEM level).
Check actuator ramp time [ch. 6.9.1].
Ramp time should not be less slowest ac-
tuator
Reduce path between special positions.
(1
Check actuator position, if necessary turn
back mechanically.
Check CAN Bus connection [ch. 5.1].
Reset W-FM, see [ch. 9.1].
If the error occurred during a parameter
change:
Check parameter that was last changed for
plausibility.
If the reset does not achieve a fault free con-
dition:
Load data from the ABE [ch. 6.16.1].
If none of the actions listed leads to a fault
free condition:
Replace W-FM.
Check SpecialPositions.
Valid position range: 0 ... 90°
