First Claim
1. A system for providing notification of a vehicle event to an operator outside the vehicle, the system comprising:
- a reader device connected to a control unit via a plurality of data lines, the control unit providing status of at least one vehicle condition wherein the vehicle is equipped with a diesel particulate filter (DPF);
a plurality of warning devices connected to the reader device; and
a power supply connected to the reader device and to the warning devices, wherein the reader device;
receives data from the control unit;
decodes the received data to detect the occurrence of a vehicle event relating to the DPF; and
