The ZD30 (non CRD) ecu uses Consult I protocol for diagnostics. Even cars equipped with an OBDII connector require Consult I software. None of the standard OBDII software will work.
We recommend using NDS I Windows PC software or NDS I Android app.
A Consult I adaptor is required to connect to the car. Cars equipped with an OBDII connector require a Consult I adaptor with an OBDII plug. Those are available from ECUtalk and buyOBD.
The ZD30 CRD ecu uses CAN bus for diagnostics. We recommend using NDS III Windows PC software with a Vag K+CAN adaptor.
