- Charging system (alternator) test
- OBD2 code reading on supported configurations
- Printable test reports
What You Can Diagnose
The BT705 helps you identify root causes faster by reading fault codes, live sensor values, and module status across the systems it supports:
- Engine, fuel, ignition, and emissions systems
- ABS, traction control, and electronic parking brake
- SRS/airbag, seatbelt, and occupant detection modules
- Transmission, transfer case, and driveline modules
- HVAC, body, lighting, and convenience control modules
Service & Maintenance Functions
Beyond reading codes, this scanner runs guided service routines that save money on dealer labor. Available functions depend on your vehicle make, model, and year:
- ABS bleed (when bundled with compatible scanner firmware)
How to Use This Tool
The BT705 communicates with manufacturer-specific modules over the OBD2 port. Use bi-directional tests to activate fans, fuel pumps, and actuators for hands-on troubleshooting. Service functions reset maintenance indicators and perform relearn procedures that normally require a dealer visit.
Vehicle Compatibility
12V/24V commercial and passenger batteries. OBD2 and ABS functions depend on bundled scanner model — verify your kit.
Always verify that your exact year, make, model, and engine combination is supported before purchase — especially for service resets, bi-directional tests, and brand-specific modules. OBD2 port location is typically under the driver-side dashboard on U.S. vehicles from 1996 onward.
Who Should Buy This
Fleet maintenance, diesel pickups, and shops testing both batteries and basic vehicle codes.
If you regularly work on your own vehicles, run a small repair shop, or buy used cars to flip, the BT705 pays for itself quickly compared to per-visit dealer diagnostics.
