Check the cause
Acknowledge that this is a software and configuration error, not a mechanical failure
Check if the underlying module has suffered a hard failure and will no longer accept a software flash
Repair steps
Contact your dealer
The official OEM guidance across all service documentation is strictly to contact your dealer, as this is a software and configuration error rather than a mechanical failure.
Reconfigure digital input parameters
Connect the tractor to AGCO's proprietary diagnostic software (Tech Connect Diagnostics / TCD-CV) to re-flash or reconfigure the digital input parameters.
