1. 1

   Perform a key cycle: Turn the ignition off, wait a few moments, and turn it back on to see if the module resets and the code clears.

2. 2

   Perform a tactile inspection: With the machine off, press the Auto 4WD button on the CommandARM multiple times. Feel for the normal tactile click and ensure the button springs back up freely.

3. 3

   Perform a visual inspection: Check the edges of the Auto 4WD button for lodged dirt, dust, or sticky residue (such as spilled beverages) that could be physically holding the plastic switch down.

1. 1

   Clean the Switch

   Disconnect the battery. Use compressed air and a plastic-safe electrical contact cleaner around the edges of the Auto 4WD button. Gently work the button up and down to dislodge any debris. Allow it to dry, reconnect the battery, and test.

2. 2

   Replace the CSM

   If the button is internally broken or shorted, individual buttons on the CommandARM are generally not serviceable on their own; the entire Cab Switch Module must be replaced.

3. 3

   Removal

   Power down the machine and disconnect the battery. Remove the trim panels on the CommandARM to expose the CSM assembly.

4. 4

   Disconnection

   Carefully unplug the electrical harnesses routed to the bottom of the CSM.

5. 5

   Installation

   Unbolt the faulty CSM and install the new unit. Reconnect the harnesses and reassemble the armrest trim.

6. 6

   Software Configuration

   Installing a new CSM often requires a software payload download and calibration via John Deere Service ADVISOR to configure the module to the tractor's specific options (such as the number of SCVs and transmission type).
