Zed-FULL EXTERNAL ANTENNA (ZFHC-EA)

This is an external antenna used on some VAG group vehicles with a CAN bus system (up to 2009 models) to collect data from the ignition. This data is used to calculate the 7th byte of the CS code during key programming when all keys are lost.

Additionally, it can be used with the Zed-FULL plus to test the ignition antenna (for example, to see if a signal is being sent). However, for calculating the 7th byte, this antenna can only be used with the Zed-FULL, not the Zed-FULL plus.
