C140 Hydraulic oil restriction

tonyoz · Aug 29, 2011

The hydraulic oil restriction light came on 2 days ago in the C140. I refered to the manual which says to pull the plugs on each filter senser to locate which filter is blocked which I have done but the light remains on,(only when the engine is running).

Question, has anyone else had this problem and what was the fix?

Hi, im with the FECON product support team.
If you have not over looked a filter, a bad LCM or a dash panel can give a false reading of this type.
What痴 the hydraulic oil temp reading?

The oil temp is good,not even half way up the gauge

Try Pulling the dash panel unplug the connector on back.
Check the 5A wire for power with the unit running if the wire is not hot, it痴 the dash panel.
If it has power, the LCM is sending a false signal to the dash. A restricted filter sends the signal through the LCM to the dash.
