Hva betyr feilkoden?
The AEM has registered a signal that is too low or too high, or a break, on the speed wire to the radio, and the fault is permanent. The fault normally goes unnoticed by the driver. The cause may be a short to ground or supply voltage, a break in the wire, or a faulty radio.

Hva du kan gjøre
