Hva betyr feilkoden?
The code concerns the control signal from the general courtesy lighting, which belongs to the roof lamp. It is set when the control module registers a faulty signal from it. UEM-0035 and UEM-0037 are often stored together with this code. The fault comes from a break or a short to voltage in the signal wire, or from the connection to the roof lamp control unit not sitting properly.
