Co oznacza ten kod błędu?
The control modules in the rear doors (LDM/RDM) power the LED in the central lock button that shows the locked or unlocked state, and they send information about it to the driver or passenger door module (DDM/PDM). The control module has registered a signal voltage that is too low when it tries to light the LED. The cause is a power supply cable short-circuited to ground.
