Hi all, my bike runs fine, yet to go through the MOT, I'm sure they'll pick up on it, but from what I have found, 54 has something to do with either the rear angle sensor/circuit.

Anyone with experience with this fault code, any information on it would be a great help. I'm a new rider and this is my first bike. I'm not mechanically inept, but I'm definitely a novice.

Thanks all,

Tom

 

Hi Tom, its the Lean angle sensor, and can be checked out with a multimeter

 

Thanks, That's located near the flasher relay if I'm not mistaken?

 

Picture here Tom,turn on ignition , multimeter on volts, connect negative lead of multimeter to the green/orange wire and the positive lead of the multimeter to the white red wire, you should get a reading of between 4.75 and 5.25 volts, if not check wires from sensor back to ecu for poor connections
