Tire Pressure Monitor (RDC): Notes

The Tire Pressure Monitor (RDC) is a system which monitors the tire pressure while the vehicle is in motion. It is offered exclusively in the USA (legal requirement) and as optional equipment (SA2VB).

The system of the new generation (Generation 3) now consists only of 5 components: the RDC control unit (control unit with integrated reception aerial) and 4 sets of wheel electronics.
