Overview
Combining a ten inch bidirectional scan tool with a battery and load tester, the bundle covers diagnostics and battery checks. The title also lists a function for ECU reprogramming work.
Pairing scanning with battery testing makes sense for a shop or serious home garage. Nothing is described beyond the title, however: supported vehicles, update terms, operating system, accessories and warranty are all absent.
Who it's for
Independent shops and advanced hobbyists who expect to work beyond basic codes. Casual owners do not need pass-thru or load testing.
Pros and cons
- Large screen scanner
- Bidirectional control named
- Pass-thru function listed
- Battery tester in the bundle
- Vehicle coverage not listed
- Update terms not stated
- Accessories not described
- Warranty not given
Performance notes
Results depend on the vehicle coverage and the software behind the scanner, none of which is documented. A load tester checks a battery under demand rather than at rest. Pass-thru work relies on manufacturer software and a stable power supply.
