Aftermarket Diagnostic Scanner
The Topdon UltraDiag is a mid-range professional diagnostic scanner from Topdon, supplied as a handheld or tablet with a Bluetooth VCI. It offers full-system fault reading and clearing, live data, active tests and a wide range of maintenance resets — oil, EPB, SAS, BMS, DPF, throttle and TPMS among them — across most common makes and models. It is aimed at independent workshops and mobile mechanics who need solid all-system coverage without the cost of a flagship platform. Software is kept current through Topdon's subscription updates, which add new models and service functions over time. Coding depth depends on the specific vehicle and software package.
UltraDiag reads, clears and resets over OBD; Softechpro edits the ECU firmware to remove DPF/EGR/AdBlue/DTC triggers and corrects the checksum, so it complements the scanner in a tuning workflow.
