Product Description

The TEIN SPS12-R3550 is a plug-and-play Error Canceller Kit designed for the 2020-2026 Toyota GR Supra (MK5/J29/A90/A91) equipped with factory Electronic Dampening Control. When aftermarket coilovers or shocks are installed in place of the OEM adaptive dampers, the Supra's ECU detects the missing electronic solenoids and triggers a dash warning light. This kit eliminates that error by connecting directly to each of the four OEM EDC wiring harness plugs, simulating the factory suspension electronics so the ECU no longer registers a fault. Each canceller module uses an OEM-style connector for true plug-and-play installation with no cutting, splicing, or ECU reprogramming required. The kit is compatible with any brand of aftermarket coilovers or shocks, not just TEIN products. Includes four canceller units and all necessary mounting hardware. Backed by TEIN's Limited Manufacturer's Warranty.
