Fendt 04.1.87 – Transmission Control system: S061 - Switch, rapid reverse on the steering wheel adjustment

A plausibility error at the Forward/Reverse (F/R) rapid reverse switch. The system detects that the electrical signals coming from the switch do not match logically, rendering the rapid reverse function on the steering wheel adjustment lever inoperable.

1. 1

   Check the S061 rapid reverse switch (located on the steering wheel adjustment lever) for physical damage, sticking, or debris.

2. 2

   Inspect the wiring harness and connector X1040 for the S061 switch. Look for loose pins, corrosion, or wire chafing in the steering column area.

3. 3

   Connect the FENDIAS diagnostic tool to monitor the live state of the Forward/Reverse switch to confirm if the signal is dropping out or stuck in one state.

4. 4

   Refer to the Fendt workshop manual Chapter 9000 Reg. E (Transmission manual control) for specific pin-out testing of the rapid reverse circuit.

1. 1

   Disconnect Power

   Turn off the tractor and disconnect the battery to prevent electrical shorts.

2. 2

   Access the Switch

   Remove the plastic cowling/covers surrounding the steering column to expose the steering wheel adjustment lever mechanism.

3. 3

   Disconnect Wiring

   Locate the S061 switch on the adjustment lever and carefully unplug electrical connector X1040.

4. 4

   Remove the Faulty Switch

   Unbolt or unclip the S061 switch from its mounting point on the steering column assembly.

5. 5

   Install the New Part

   Mount the replacement switch into the factory position and securely reconnect the X1040 wiring harness.

6. 6

   Reassembly

   Reinstall the steering column covers.

7. 7

   Testing

   Reconnect the battery, turn on the tractor, and test the rapid reverse function. Use the FENDIAS system to clear the 04.1.87 fault code and verify it does not return.
