1. 1

   Press and release Button 4 on the navigation bar to attempt to reset and recover the system

2. 2

   Turn the ignition switch off, wait a moment, and turn it back on to see if the code clears

3. 3

   Inspect the W577 Armrest Navigation Bar Module Extension Harness for any pin damage, corrosion, or loose connections

1. 1

   Power down the machine and disconnect the battery to ensure safety while working on cab electronics.

2. 2

   Access the armrest console and locate the A048 Armrest Navigation Bar Module.

3. 3

   Disconnect the W577 extension harness and test for continuity between the navigation bar module and the Cab Switch Module (CSM) to rule out a wiring short or open circuit.

4. 4

   If the wiring harness tests good, the fault lies internally within the button contacts of the Armrest Navigation Bar Module or the CSM itself.

5. 5

   Replace the faulty Armrest Navigation Bar Module or the Cab Switch Module (CSM).

   Note: Because the CSM is a complex and expensive electronic component, some specialized agricultural electronic repair shops offer component-level repair for the CSM on a time-and-materials basis if a new replacement is unavailable.

6. 6

   Reassemble the armrest, reconnect the battery, and cycle the key to verify the code has cleared.
