Hello all bbshd owners.

I've still not solved the error 21 issue which results in Pas not working, motor is working fine with throttle though.

All cables are fine.

Bought new speed sensor but still the same. Works as good as the old one
Checked magnet alignment and it works fine, getting a speed readout and sensor reacts to magnet as it should.

Not using any brake sensors or gear sensors.

Can someone think of the something causing error 21 speed sensor error to occur when it's obviously not the speed sensor that is the problem?
