Explore how this module impacts your diagnostic procedures and what tools can help you overcome these challenges. Learn about diagnostic communication, ECU programming, and automotive cybersecurity.

1. What Is The Secure Gateway Module (SGW) And Its Purpose?

The Secure Gateway Module (SGW) is a module implemented in some models in the 2018 model year and all models 2019 onward, designed to secure vehicle communication networks by creating a firewall between the public and private sectors of the network. Its primary function is to protect the vehicle’s internal networks from potential cyber threats and unauthorized access. According to Chrysler factory training, the SGW isolates vulnerable components such as telematics/radio units and the DLC (Diagnostic Link Connector) to prevent exploitation.

The SGW’s role in securing vehicle networks is crucial. By separating the network into public and private sectors, it limits access to critical vehicle functions without proper authentication. This separation means that while certain diagnostic functions like reading codes and data are accessible, more invasive procedures such as clearing DTCs (Diagnostic Trouble Codes), performing actuator tests, or reconfiguring the ECU (Engine Control Unit) require authentication.

This authentication process is generally limited to Chrysler-licensed devices, such as the Micropod II and J2534 devices used with wiTECH 2.0. The need for authentication is driven by increasing concerns over vehicle cybersecurity. In a world where vehicles are more connected than ever, the risk of malicious actors gaining access to vehicle systems is a serious threat. As highlighted in a YouTube video shared by Robby Schrimsher, hackers were able to exploit vulnerabilities in a 2014 Cherokee to take control of vehicle features, demonstrating the potential dangers of unsecured networks.

The SGW’s design reflects a proactive approach to addressing these vulnerabilities. By isolating the DLC, the module minimizes the risk associated with aftermarket devices that may not adhere to stringent security standards. Many vehicles are equipped with dongles from insurance companies, code readers, or fleet trackers, which could potentially serve as entry points for malicious attacks.

The implementation of the SGW is not just a measure to protect against external threats but also to ensure the integrity and reliability of vehicle systems. Unauthorized modifications or interventions can lead to unpredictable behavior and compromise the safety of the vehicle and its occupants. Thus, the SGW is a critical component in maintaining the overall security and performance of modern vehicles.

2. How Does The SGW Work By Separating The Vehicle Network?

The SGW works by segmenting the vehicle network into public and private sectors, with the public sector including the telematics unit and the DLC, while the rest of the network is considered private and requires authentication for access. According to Chrysler’s network structure, the SGW physically separates the DLC via Diagnostic CAN C and Diagnostic CAN IHS buses.

To elaborate, the SGW serves as a gatekeeper, controlling the flow of information between the public and private sectors of the vehicle’s network. This segmentation is crucial for preventing unauthorized access to sensitive vehicle systems. Let’s break down how this separation works:

• Public Sector: This segment includes components that are more exposed and potentially vulnerable, such as the telematics unit and the DLC. The telematics unit is responsible for functions like GPS tracking, remote diagnostics, and over-the-air (OTA) updates, while the DLC is the port used for connecting diagnostic tools.
• Private Sector: This segment encompasses the core systems of the vehicle, including the engine control unit (ECU), transmission control unit (TCU), anti-lock braking system (ABS), and other critical modules. Access to this sector is restricted to prevent unauthorized manipulation of vehicle functions.

The SGW achieves this separation through its physical network structure. On a 2018 Ram, the DLC connects directly to the SGW via dedicated Diagnostic CAN C and Diagnostic CAN IHS buses. The SGW is also connected to the CAN C and CAN IHS buses but is not directly connected to the LIN bus. Additionally, it connects directly to the radio via CAN C and IHS buses.

It’s important to note that the SGW does not function as a central gateway for inter-module communication. Instead, it acts as a frame gateway, allowing only authenticated messages to pass through to the private networks. The module itself does not contain any drivers and does not directly control any vehicle components.

This architecture ensures that any communication with the private network must first pass through the SGW, where it is subjected to authentication. This process verifies that the device or user attempting to access the network is authorized to do so. Without proper authentication, access is limited to read-only functions, such as reading diagnostic trouble codes (DTCs) and data.

The authentication process typically involves communication with Chrysler’s servers, which validate the credentials of the diagnostic tool. As of now, only Chrysler-licensed devices, such as the Micropod II and J2534 devices used with wiTECH 2.0, can be authenticated.

This stringent security measure is designed to protect against various cyber threats, including:

• Unauthorized Access: Preventing malicious actors from gaining control of vehicle systems.
• Data Manipulation: Ensuring the integrity of vehicle data and preventing tampering.
• Remote Attacks: Protecting against remote attacks that could compromise vehicle safety and performance.

By implementing the SGW and segmenting the vehicle network, manufacturers can significantly enhance the security of modern vehicles and mitigate the risks associated with increasing connectivity.

3. What Is The Authentication Process For SGW Access?

The SGW authentication process involves using Chrysler-licensed devices such as Micropod II or J2534 devices with wiTECH 2.0 to communicate with Chrysler servers, which verify the tool’s credentials for accessing the private network. AE Tools’ Joey explains that wiTECH subscription is locked to the software when using a J2534 device, whereas Micropod II locks the subscription to the tool itself, allowing use on multiple devices with an internet connection.

To further clarify, the authentication process is a critical step in accessing the protected functions of a vehicle equipped with an SGW. Here’s a detailed breakdown of how it works:

1. Device Requirement: As mentioned earlier, accessing the private network requires a Chrysler-licensed device. Currently, the primary options are the Micropod II and J2534 devices, both of which are compatible with wiTECH 2.0, Chrysler’s diagnostic software.
2. wiTECH Subscription: A valid wiTECH subscription is necessary to authenticate the diagnostic tool. The subscription provides the necessary credentials to communicate with Chrysler’s servers and verify the tool’s legitimacy.
3. Authentication Process: When a diagnostic tool attempts to perform a function that requires access to the private network, such as clearing DTCs or performing actuator tests, the SGW initiates the authentication process. The tool sends a request to Chrysler’s servers, which then verify the tool’s credentials.
4. Credential Verification: Chrysler’s servers check the tool’s subscription status and other relevant information to ensure that it is authorized to access the private network. If the credentials are valid, the server sends an authentication token back to the tool.
5. Access Granted: Once the tool receives the authentication token, it can use it to access the protected functions of the vehicle. The SGW allows the tool to perform the requested action, such as clearing DTCs or performing actuator tests.

The choice between using a Micropod II and a J2534 device depends on specific needs and preferences. Here are some key differences to consider:

• Micropod II: This device locks the wiTECH subscription to the tool itself, allowing it to be used on multiple devices with an internet connection. It communicates directly with Chrysler’s servers via WiFi.
• J2534 Device: This device locks the wiTECH subscription to the software, essentially tying it to a specific computer. It uses drivers and downloaded software to port to the wiTECH cloud. An internet connection is required at all times, including during test drives.

Additionally, it’s important to note that the J2534 wiTECH software only offers coverage from MY 2010 forward, while the Micropod II coverage goes back to 2004 on CAN vehicles and covers all models 2009 forward.

The authentication process is a critical component of the SGW’s security architecture. By requiring authentication for access to the private network, Chrysler can ensure that only authorized devices and users can perform sensitive functions on the vehicle. This helps to protect against cyber threats and maintain the integrity and reliability of vehicle systems.

4. How Does The SGW Impact Aftermarket Diagnostic Tools?

The SGW limits unauthorized aftermarket devices to read-only or passive access, preventing them from performing functions like clearing DTCs, actuator tests, ECU configuration, flashing, or module resets on the private side of the network. As a mobile tech, the demand for code clearing is expected to grow until the aftermarket develops a solution.

Delving deeper, the implementation of the SGW has significant implications for aftermarket diagnostic tools and technicians. The primary impact is the restriction of access to certain functions on the vehicle’s private network. Without proper authentication, aftermarket tools are limited to read-only capabilities, which means they can only read diagnostic trouble codes (DTCs) and data.

This limitation has several consequences for aftermarket diagnostic services:

• Reduced Functionality: Aftermarket tools cannot perform essential functions such as clearing DTCs, performing actuator tests, ECU configuration, flashing, or module resets. This restricts the scope of repairs and maintenance that can be performed using these tools.
• Increased Demand for OEM Tools: The limitations imposed by the SGW increase the demand for OEM (Original Equipment Manufacturer) tools, which are authenticated and have full access to the vehicle’s systems. This can create challenges for independent repair shops and mobile technicians who rely on aftermarket tools.
• Need for Alternative Solutions: The restrictions imposed by the SGW have spurred the development of alternative solutions by aftermarket tool manufacturers. These solutions aim to provide access to the private network without compromising vehicle security.

Several aftermarket tool manufacturers are working on solutions to address the challenges posed by the SGW. For example, Autel is releasing a 12+8 adapter that bypasses the SGW, allowing full network capability. This adapter essentially replaces the SGW and requires removal of the unit, which is typically located under the driver’s side of the dash or behind the infotainment unit.

However, the use of such adapters may not be ideal in all situations. Removing the infotainment unit can be time-consuming and may not be practical for all repairs. Additionally, there are concerns about the potential for security vulnerabilities when bypassing the SGW.

Despite these challenges, the aftermarket is actively working to develop solutions that provide access to the private network without compromising vehicle security. These solutions may involve integrating with OEM systems, using pass-through devices, or developing new authentication methods.

As the demand for aftermarket diagnostic services continues to grow, it is essential for aftermarket tool manufacturers to develop innovative solutions that address the challenges posed by the SGW. This will ensure that independent repair shops and mobile technicians can continue to provide comprehensive diagnostic and repair services for modern vehicles.
