Important Compatibility Notice
Compatibility must be confirmed using the module type, MCU mask number and memory-chip reference—not only the vehicle model and production year. Please check the CAS, EWS, EZS, SRS or ECU reference before ordering.
Always create and securely save a complete backup before writing or clearing data. Stable power and correct wiring are essential during programming.
This product is intended for qualified automotive technicians and lawful module repair, replacement and data-recovery work. Any odometer-related function must only be used for legally permitted repairs and accurate restoration of the vehicle’s original documented mileage.
