What is an OBD2 Scanner?
An OBD2 scanner (On-Board Diagnostics) is a tool that connects to a vehicle’s onboard computer to retrieve fault codes, monitor live data, and diagnose engine and system problems. All vehicles manufactured after 1996 come equipped with an OBD2 port, allowing for easy diagnostics.
Why Use a Mercedes-Benz Specific OBD2 Scanner?
While generic OBD2 scanners can read basic codes, Mercedes-Benz vehicles use a specialized system that requires a more advanced diagnostic tool. A Mercedes-Benz specific OBD2 scanner can access manufacturer-specific codes and provide more in-depth analysis, covering systems such as:
- Engine control module (ECM)
- Transmission
- ABS (Anti-lock Braking System)
- Airbag and SRS (Supplemental Restraint System)
- Live data monitoring
