Zed-Full™ ZFH-EA5 52-Pin MCU Test Clip: In-Circuit MCU Reading for BMW™ EWS3 / EWS3+
The Zed-Full™ ZFH-EA5 is a professional 52-pin MCU test clip engineered for reading and extracting data from BMW™ EWS3 and EWS3+ immobilizer systems. It connects directly to the module, allowing true in-circuit reading (in-circuit / on-board reading) without removing the microcontroller, which helps reduce risk, save time, and improve reliability during service operations.
This accessory is ideal for locksmiths, automotive key specialists, and electronics technicians using Zed-FULL™ and dedicated IEA™ connection cables for BMW™ EWS platforms.
