Buying a scan tool is frustrating when you cannot tell if it will actually work on the cars you see every day. A lot of tablets look pro until you hit a deeper module scan, a stubborn ABS light, or a no start that needs more than basic code reading. Then you are stuck bouncing through menus, guessing at parts, or sending the job out and losing time and money. If you also do keys, most tools force you into a second device or pricey add ons that do not play nice together. That is exactly why the UltraDiag is built to be a true all around automotive diagnostic scan tool you can trust in the bay.
The UltraDiag is a diagnostic scan tablet that covers the full picture, not just the check engine light. It delivers full system diagnostics across 100 plus vehicle brands and scans modules like engine, transmission, ABS, airbag, TPMS, immobilizer, gateway, steering, radio, and HVAC. You can read and clear DTCs, pull freeze frame data, and watch live data streams to confirm what is actually happening in real time. When you need to stop guessing, bidirectional control lets you command components to test the system on purpose. It is an OE level scan tool style workflow in a practical tablet that keeps you moving on real jobs.
Where the UltraDiag really opens doors is key and immobilizer capability for shops that want new revenue without adding another tablet. With the key programming add on, it supports common locksmith style functions like PIN reading, key learning, remote control learning, delete keys, and all keys lost for compatible vehicles. It also supports FCA Secure Gateway access through AutoAuth, so you can work confidently on Chrysler, Dodge, Jeep, and Fiat with compliant access (AutoAuth subscription required). On the hardware side, the 8 inch screen, Android 11, 10,000mAh battery, and Bluetooth VCI keep it comfortable to use all day. If you want a professional scan tool that handles core diagnostics plus key work, TOPDON UltraDiag is a strong fit for shop owners, techs, and locksmiths.
