Product Description

The **RS-R DWCT215 Electronic Damper Control (EDC) Warning Canceller** is a specialty performance electronics module designed for the **Toyota GR Supra (A90)** produced from **2020 through 2024**. When upgrading suspension components - such as installing non-electronic coilovers or altering the factory adaptive system - the Supra's EDC system may trigger error messages or warnings on the dashboard. This RS-R unit intercepts and cancels those warnings so the vehicle can operate smoothly without unwanted alerts related to damper control changes.

Installation is plug-and-play, requiring no wiring modifications or advanced diagnostics. Simply connect the module between the vehicle's suspension control harness and the factory electronic damper system to eliminate false EDC warning lights and restore normal traction control functionality. The DWCT215 is particularly useful for Supra owners who are modifying their suspension or choosing aftermarket damping solutions that don't interface with Toyota's original EDC system.
