Electro Hydraulic Remote #3 Lever Flow Control Pot Data Is Set To The Error
State
Cause:
The Data Bus signaled that AUX 3 flow limit potentiometer (the 3rd variable flow control) is set to error state.
The AUX/Hitch/PTO controller received the signal from the armrest controller.
Possible failure modes:
1. AUX 3 flow limit potentiometer has failed in the armrest controller (in most cases).
2. Software execution error in the armrest controller (small chance).
Solution:
The 3rd variable flow control is on the secondary control panel of the armrest controller. If the 3rd variable flow
control fails in the armrest controller, the fault code ARM 109 should exist.
1. Check for fault code ARM 109 at the armrest controller. If ARM 109 exists, test the function of the 3rd variable
flow control.
Connect the service tool to the tractor Data Bus, do the following:
Go to the Monitor screen by click the Monitor Icon.
Click the CHANGE PARAMETER SELECTIONS Icon.
Click the ARMREST AUX REMOTE 3 FLOW CONTROL and then ADD. Next click EXIT. You will now be able
to monitor the 3rd variable flow control status on the screen.
Turn the flow control up and down, and watch the status change from 0 to 100%.
If the status display matches the pot changes, the flow control is working OK.
If the service tool is not connected to the tractor Data Bus or the status display does not match the
potentiometer changes, inspect the potentiometer.
The flow control potentiometer is an integrated part of the second panel of the armrest console. If it is
suspected that the potentiometer failed, replace the panel.
2. If ARM 109 does not exist or the 3rd variable flow control is working OK, check the function of the armrest
controller.
NOTE: See schematic sections 47 and 48 on the schematic poster.
