Fendt Y035 – ECU EMR2: EMR Actuator Out of Allowed Range

The Electronic Engine Control (EMR) actuator is operating outside of its permissible range, meaning its actual position does not match the position commanded by the engine control unit. This discrepancy can lead to improper engine function. A difference of more than 10% between the target and actual control travel triggers this fault.

1. 1

   Cycle the tractor's ignition off and on to see if the fault clears, as the error may disappear if the actuator's current returns to the normal range

2. 2

   Visually and mechanically inspect the EMR actuator's control rod for smooth and unrestricted movement, checking for any binding or obstruction

3. 3

   Use Fendt's SERDIA diagnostic software to check the actuator's feedback and target positions

4. 4

   Inspect the wiring harness between the EMR actuator and the EMR2 ECU for signs of damage, corrosion, or loose connections

5. 5

   Check the voltage supply to the EMR2 ECU

1. 1

   Perform initial diagnostics

   Complete all visual, mechanical, and electrical diagnostic checks to rule out issues with wiring, control rod movement, or the ECU itself.

2. 2

   Replace EMR actuator

   If diagnostic checks point to a faulty actuator, replace it with a new unit.

3. 3

   Clear fault codes and verify

   Use the FENDIAS diagnostic system to clear the fault code memory and ensure the new actuator is functioning correctly.
