Co oznacza ten kod błędu?
On the V40, The CEM has no power from one of its two supply cables. The loads are split between both cables, so a break in one leaves only part of the exterior lighting, for example, without power. One of the supplies also feeds the fuel pump, so the engine cannot be started while the fault is present.
