Toyota - Deactivation of Adaptive Suspension / EDC

After installing coilovers or a non-adaptive suspension, it is essential to deactivate the adaptive suspension (EDC) system . This coding electronically disables the control of the adaptive dampers and prevents error messages from appearing on the dashboard, while ensuring proper vehicle operation.

Features :

• Complete deactivation of the EDC system – removal of electronic control of the shock absorbers.
• No dashboard errors – no more “Defective Suspension” message after installing coilovers.
• 100% software solution – no additional parts or modules!
• Compatible with all brands of coilover suspension – BC Racing, KW, H&R, Bilstein, etc.
• Retroversible – possibility to reactivate the original EDC system at any time.

Why perform this coding?

When switching to threaded rods or a non-adaptive suspension, the control unit detects the absence of adaptive dampers and generates errors. This EDC coding allows the system to be properly deactivated without affecting other electronic functions (DSC, driving modes, etc.).

Compatibility:

• Toyota Supra GR MK5

⚠ WARNING: Coding must be performed by a professional. This service is recommended only after replacing the original electronically controlled suspension with a fixed or threaded suspension.
