I have a 2015 F4 RR. Does anyone know if these bikes will turn on the ABS light if the brake pads are extremely low?

Can you describe the fault?

Does the light come on when the ignition is turned on?
Does the light go off after you start to move?
Do you get the error come up on the LED and on the display hazard triangle and ABS (where the trip mileage should be), if so is it only after you reach speeds of 14mph or 24kph, and does the warning disappear after you stop?

What mode do you have the ABS in? On, race or off?

I'm not aware of any connected issue to the brake pads as there are no wear sensors. ABS faults can be caused by;
Either of the 2 speed sensors being damaged, although these tend to be displayed as individual errors
Encoder ring being damaged or not in range
Air in the brake circuit
if its just the LED, putting it in ABS OFF mode.
to name a few.

The problem with the ABS faults is that it is not part of the MV system, the diagnosis is directly with the Bosch controller so if you cant find the issue, its off to MV

Answered your questions inline to make it easier to track.

Can you describe the fault?

Does the light come on when the ignition is turned on? Yes, it turns on along with all the other lights when ignition is turned on. When I start moving though, the ABS light doesn't turn off like it normally should.
Does the light go off after you start to move? No, it stays on regardless of the speed.
Do you get the error come up on the LED and on the display hazard triangle and ABS (where the trip mileage should be), if so is it only after you reach speeds of 14mph or 24kph, and does the warning disappear after you stop? I believe I may have seen it flash ABS Fault once or twice, but generally the hazard triangle isn't shown.

What mode do you have the ABS in? On, race or off? Custom mode, but ABS is on.

Cool, thanks for the help. The bike's already at the dealer for a valve adjustment so I'll just have them diagnose the ABS issue as well. I just brought up the brake pads because I remember they were super low after my last track day, but didn't want the dealer to waste 3 hours of labor chasing down a ghost if it was just a brake pad issue.

Hi,
even though you are custom mapping mode, the ABS is not part of that. The ABS has its own menu which on the F4 is On, Race or OFF. If Off and I think Race (i'll check tonight, the LED always stays on to say 'hey ABS is not protecting you"

cheers

Ah, that's good to know. I assumed the Custom map included the ABS settings. I'll call the dealer and have them check to make sure I didn't turn off ABS at the track and forgot about it... Sadly, this would not be the most retarded thing I've done in the past.
