The RS-R EDC Canceller is an electronic damper control warning canceller intended for Toyota Supra applications with EDC systems. It prevents or clears EDC-related warning indications when aftermarket suspension components are used or when the factory damper control signals need to be modified. The unit targets the Supra's electronic damper control circuit to restore a clean instrument-cluster indication.
