Co oznacza ten kod błędu?
The driver and passenger door modules control the illumination of the switch panels in the doors. The fault is stored when the voltage on the signal wire is too low, because the supply wire has contact with ground, or because of moisture and oxidation in the connections. The illumination is then switched off.
