1. Understanding SRS Modules and OBD2 Scanners

Let’s explore what an SRS module entails and how OBD2 scanners function to grasp whether an OBD2 scanner can reset an SRS module.

1.1 What is an SRS Module?

The Supplemental Restraint System (SRS) module serves as the central control unit for your vehicle’s airbag system, overseeing airbag deployment and seatbelt pre-tensioners. According to the National Highway Traffic Safety Administration (NHTSA), SRS modules play a crucial role in mitigating injury during collisions.

• Purpose: The SRS module’s primary function is to monitor sensors and deploy airbags when a collision occurs.
• Functionality: This module receives data from impact sensors and determines whether to activate airbags.

1.2 What is an OBD2 Scanner?

An On-Board Diagnostics II (OBD2) scanner is a tool used to access a vehicle’s computer system, which helps in diagnosing problems and clearing error codes. As stated in a report by the Society of Automotive Engineers (SAE), OBD2 scanners have become standard equipment in modern automotive repair.

• Basic Functionality: Reads and clears engine and transmission-related error codes.
• Advanced Capabilities: Some high-end scanners can interact with systems like ABS, SRS, and more.
