Front suspension position is below the lower suspension range
Cause:
The transmission controller monitors the front axle potentiometer circuit. If the transmission controller detected the
voltage is 0.62 Volts below the mid calibrated point for 30 seconds, this fault code will be recorded.
Solution:
1. Check if the front suspension position has been below the lower range for too long.
When the front axle suspension is turned on, the system should bring the axle within the range quickly.
Make sure the tractor is properly ballasted and the front weight is proper for the tractor.
Check the installation of the front axle position sensor.
Make sure the front axle position sensor is properly installed. There is no mechanical damage or blockage
preventing the suspension back to the mid point.
If the above checks are all OK, go to next steps.
2. Check for electrical problems.
Check for fault codes involving Raise, Lower, Upper lock, and Lower lock solenoid failures.
Make sure all solenoids have been connected and electronically function OK.
3. Check for hydraulic problems.
Check the hydraulic system.
Make sure all circuits are well connected, the accumulators are properly charged, the pressure and flow are
within the range.
