1. What is an OBD2 Scanner SRS ABS?

An OBD2 scanner SRS ABS is a diagnostic tool that reads and interprets data from a vehicle’s onboard computer system, specifically focusing on the Supplemental Restraint System (SRS) and Anti-lock Braking System (ABS). It helps identify malfunctions, reset warning lights, and ensure these critical safety systems are functioning correctly.

OBD2 scanners that include SRS and ABS functionality are essential for modern vehicle maintenance, offering capabilities to diagnose issues within airbag systems and braking controls. According to a study by the National Highway Traffic Safety Administration (NHTSA), faulty SRS and ABS systems can significantly increase the risk of accidents and injuries. Therefore, regular diagnostics with a reliable scanner are crucial for vehicle safety.

1.1. Key Functions of an OBD2 Scanner SRS ABS

The primary functions of these scanners include:

• Reading Diagnostic Trouble Codes (DTCs): Retrieves codes indicating specific problems within the SRS and ABS.
