Hva betyr feilkoden?
This fault concerns the automatic transmission. The CEM has registered that the relay driver for the extended X-supply relay to the automatic transmission is short-circuited to supply voltage, and the fault is intermittent. It was present at an earlier time but is no longer there. Gear changes may then fail to happen.
