TC disabled and Engine warning light

[centaur62]

Sorry I should have said 2018 XRt (TFT screen) model, my bad.
Battery is steady at 12.8v, I'm no techie, don't have any analytical tools.

T800XC may know if there is a working TFT way for the code process?

What is your running voltage, mine looked correct static, but when started and no throttle.

12.8v at idle.

.... that indicates no charging then. You can see from my link my static voltage was 12.3v static but as soon as the bike is started the voltage should go up to 14.3v as it should (approx. 14.0 -14.5v)

To display stored fault codes on tft screen models do this:  With the ignition off, hold the selector joystick up and press the M button while turning ignition on. Any stored codes will be displayed after the start up screen.

Hi Stevie.P, all I have is a Hella plug for the auxiliary power socket which has a USB jack and it also has a voltage readout which on checking again shows 14.2v at idle, so I guess I'm charging.
Did as Characticus suggested and get the following codes: ECU DTC: P0500 and P1521
                                                                                     CCU DTC: C.....
                                                                                     ABS DTC: C....

Just had a look at the fault code list, the P codes indicate ABS sensor/ speedo fault and no signal to the ABS modulator so I'm pretty sure now I ruined the sensor when I mounted the magnetic foot for the dial guage on the fork stanchion.

You can usually ignore P1521 as it's just reporting a comms hiccup with the ABS module, which isn't that uncommon.

The important one in your case is P0500 "vehicle speed sensor malfunction". Sounds like your rear ABS sensor is giving you problems as this is used to monitor the bike's speed.

[centaur62]

The P0500 says Speed(Speedometer) sensor fault or ABS sensor fault, does that suggest its only the rear sensor that is out?

[T800XC]

Most likely as it's the rear ABS sensor that is used for speed pickup.

It might be badly aligned or dirty so worth taking a close look at it before replacing it.
