RS-R GR Supra Electronic Damper Control (EDC) Warning Canceler

This warning canceler is for active dampening control only. It is not effective with other suspension delete systems.

Overview

The RS-R EDC Warning Canceler is a purpose-built electronic module designed to eliminate unwanted suspension system warnings on 2020+ GR Supra equipped with Electronic Damper Control (EDC).

When the factory EDC system is removed or replaced — such as when installing aftermarket coilovers or non-EDC suspension — the vehicle’s ECU detects a loss of signal and triggers dashboard warnings or error codes. This module prevents those warnings by simulating the expected signals, preserving a clean instrument cluster and retaining normal driving mode behavior.

Key Features

• Eliminates EDC Warnings: Removes electronic damper warning lights that occur after removing or modifying the stock EDC system.

• Plug-and-Play Installation: Designed for easy installation using OEM-style connectors — no cutting or splicing required.

• Maintains Vehicle Systems: Helps ensure related vehicle systems (like drive modes and stability control) continue functioning without interruption.

• Durable and Reliable: Built to OEM-grade standards for lasting performance throughout daily driving or track use.
