A sudden drop in RPM while driving is concerning, especially if it occurs without warning and seems to resolve itself on the next start. This is exactly what makes troubleshooting difficult.
Why the fault is often not reproducible
Loose plug connections, an aging safety lanyard, or brief voltage drops in the battery often only briefly trigger a protection mechanism without leaving a permanent warning light.
Making even fleeting errors visible
With M-JET DIAGNOSTIC, even temporarily occurring error codes remain stored, so you can analyze them at your leisure after the ride, instead of waiting for the next failure.
