A diagnostic system of an LED lamp system for a motor vehicle has a light control module for controlling an LED lamp via a supply wire and in case of malfunction, the LED lamp sends a diagnostic signal via the supply wire to the light control module. Additionally, the LED lamp, in case of malfunction, modulates a received current with a switchable current sink, whereby the light control module receives coded diagnostic information via the supply wire.
