The question of whether the OBDLink MX Bluetooth scan tool can check ABS sensors is a common one among car owners and DIY mechanics alike. The anti-lock braking system (ABS) is a critical safety feature in modern vehicles, and diagnosing issues with its sensors is crucial for maintaining vehicle safety and performance. This article delves into the capabilities of the OBDLink MX Bluetooth scan tool, specifically addressing its ability to check ABS sensors and offering a detailed guide on how to utilize this powerful tool for comprehensive vehicle diagnostics.
The OBDLink MX+ Bluetooth scan tool is more than just a basic OBD-II code reader. It’s designed to provide enhanced diagnostics, going beyond the standard OBD-II protocols to access a wider range of vehicle systems and parameters. This enhanced capability is key to answering our core question: Yes, the OBDLink MX Bluetooth scan tool can indeed check ABS sensors. Furthermore, it can access and diagnose other crucial systems like SRS (Supplemental Restraint System) and TPMS (Tire Pressure Monitoring System), making it a versatile tool for vehicle maintenance and repair.
To understand how the OBDLink MX+ accomplishes this, we need to explore its enhanced diagnostic features through the OBDLink app. This app is designed to seamlessly interface with the OBDLink MX+ adapter, unlocking access to modules and parameters that are not typically available with standard OBD-II scanners. Let’s walk through the process of downloading enhanced diagnostics and navigating the app to check ABS sensors.
Downloading Enhanced Diagnostics with OBDLink App
Before you can check ABS sensors or any other enhanced diagnostics, you need to download the specific OEM add-ons for your vehicle within the OBDLink app. This process is straightforward and ensures you have access to the correct diagnostic protocols for your car’s make and model.
Pre-requisites:
- Ensure your vehicle is turned on and your OBDLink adapter is connected to your phone or tablet via Bluetooth.
- Verify that your phone or tablet is not connected to other Bluetooth/BLE devices to avoid interference.
Steps to Download Enhanced Diagnostics:
-
Initial Connection: When you connect your OBDLink adapter to the app for the first time, a prompt will appear offering options to adjust vehicle settings and download enhanced OEM add-ons. Tap on Get Enhanced OEM Add-Ons.
-
Accessing Add-ons via Settings: If you’ve connected before, navigate to the settings menu. Tap on Settings and then select Get Enhanced OEM Add-Ons to proceed.
-
Select Vehicle Manufacturer: Browse the list of vehicle manufacturers and tap on the manufacturer of your vehicle.
-
Choose Model Year: From the list of model years available for your selected manufacturer, tap on your vehicle’s model year to specify the correct diagnostics package.
-
Confirm Diagnostics Selection: Review the selected diagnostics package and tap Choose to confirm your selection for your vehicle.
-
Free Add-on Notification: You might see a notification about a free add-on available for your adapter. It’s recommended to tap GET FREE ADD-ON to maximize the features of your OBDLink adapter.
-
Download Diagnostics: Tap Get to start downloading the enhanced diagnostics for your vehicle. This process may take a couple of minutes to complete.
-
Disconnect Notification (If Connected): If your adapter is already connected, you might see a notification to disconnect for the download to proceed. Tap Disconnect to allow the app to disconnect and continue downloading.
-
Installation Confirmation: Once the download is finished, you will see confirmation that the diagnostics are installed for your vehicle.
After installation, navigate back to the home screen of the OBDLink app.
Selecting Vehicle Network for Diagnostics
For certain vehicle manufacturers (excluding GM, Honda/Acura, and Hyundai/Kia), you may need to select a specific vehicle network to access the modules you want to diagnose, including ABS.
-
Confirm Connection: Ensure your phone or tablet is Connected to the OBDLink adapter.
-
Network Selection Prompt: A dialog box will appear asking you to select a vehicle diagnostic network. Choose the network relevant to the modules you wish to access. For general use, Generic OBD2 is often recommended. Tap CONNECT after selecting your network.
-
Enhanced PID Scan (First Time Connection): If OEM Live Parameters are supported for your vehicle, the app will automatically scan for supported enhanced Parameter IDs (PIDs) on the first connection to an enhanced network. This might take a minute or two and the results are saved for future connections. Tap Yes to allow the scan to begin.
Once the scan is complete, you can proceed to view diagnostics.
Viewing ABS Sensor Diagnostics and Trouble Codes
With enhanced diagnostics downloaded and the vehicle network selected (if necessary), you are now ready to check for ABS sensor issues and other diagnostic information.
-
Navigate to Diagnostics: From the main screen of the OBDLink app, tap on Diagnostics.
-
Warning Message: A warning message will appear, reminding you to perform diagnostics safely. Tap Yes to continue.
Trouble Codes for ABS and Other Systems
The Diagnostics section opens directly to the Trouble Codes tab. Here, you will find any Diagnostic Trouble Codes (DTCs) present in your vehicle’s systems, including the ABS.
-
No DTCs: If no trouble codes are detected, you will see a screen indicating that all tests have passed, often with a green checkmark.
-
DTCs Present: If DTCs are present, including those related to ABS sensors, they will be displayed on this screen. You will also typically see a Clear Codes button.
Important Warning: Only clear codes with the ignition ON and the engine OFF. Never attempt to clear codes while the engine is running.
Tapping on a specific trouble code will open a new screen with more detailed information about that code.
Freeze Frame Data
When a DTC is generated, the vehicle’s ECU captures a snapshot of various PID values, known as freeze frame data. This data can be invaluable in understanding the conditions under which the DTC was set, potentially aiding in diagnosing ABS sensor issues or other problems. The OBDLink app provides access to this freeze frame data, helping you get a clearer picture of what occurred when the fault code was triggered.
PID Values for Live Sensor Data
The PID Values tab in the OBDLink app allows you to monitor live data from various sensors and parameters in your vehicle. While vehicle speed and engine RPM are displayed by default, you can customize this tab to include PIDs relevant to ABS sensors, such as individual wheel speed sensor readings. This real-time data can be extremely helpful in pinpointing faulty ABS sensors by observing their live outputs while driving or performing diagnostic tests.
Comprehensive Diagnostic Reports
The OBDLink app also offers a Report tab, allowing you to generate, store, load, and share detailed diagnostic reports. These reports compile information from various diagnostic tests, including trouble codes, freeze frame data, and more. This comprehensive overview can be valuable for record-keeping, sharing information with a mechanic, or tracking vehicle health over time.
