Error code
« on: June 08, 2024, 03:59:12 PM »
I'm encountering a persistent error code (21F900) on my 2014 S1000R and can't seem to identify what it means. Has anyone come across this before or have any insights?

The 2014 S1000R's 21F900 error number usually indicates an electrical system malfunction. This number may indicate a throttle position sensor or ECU issue.

Steps to troubleshoot:

Check Connections: Check throttle position sensor wiring and connectors for loose or broken connections.

Sometimes restarting the ECU fixes temporary issues. Remove the battery for a few minutes, then reconnect.

Dirt or residue might alter sensor readings, so check the throttle body.

Diagnostic kit: Read more detailed trouble codes and reset using a BMW motorbike diagnostic kit if feasible.
Visit a technician: If the problem persists, take the bike to a skilled technician or BMW dealership for a diagnostic.
