Ive a ETB electronic speedo & today when i started the car the speedo all works but the odometer display flashes . anyone know why or any ideas ?
Checked the earth wires as i thought it could have been that but no .

Is the little reset being held in somehow - if this is depressed and you turn the ignition on it starts to flash as that enters the set-up mode I believe.

HTH

Mine will only flash when the reset button is held in, so Im with mark on this one.

Give ETB a bell and ask their advice. I have on a few occasions and find them to be very helpful.

cheers

Dave
