You can configure the OBDLink® app to display alerts when vehicle Parameter IDs (PIDs) match a certain condition. For example, you may want to monitor engine coolant temperature during extreme conditions. Follow the steps in this article to configure alerts and (optionally) enable speech for those alerts.

Note: The Alerts option was recently added to the OBDLink app. If you don't see this option, download the latest version of the OBDLink app from the App Store (iOS) or Google Play (Android).  


You will see the complete set of Settings options when your phone/tablet is Connected to your OBDLink adapter.

Note: You will see different options depending on the type of OBDLink adapter that you have.


Overview

The OBDLink app displays several dashboards and diagnostic gauges by default, including engine RPM and vehicle speed. The default gauges display Parameter IDs (PIDs) that are common to most OBD-II compliant vehicles and are included in the Society of Automotive Engineers (SAE) standard. You can configure alerts for many PIDs, including default SAE PIDs and user-defined PIDs. 

An alert becomes active when the PID value matches the threshold setting for the alert. An alert becomes inactive when the value no longer matches the threshold setting. The OBDLink app triggers an alert action whenever the alert becomes active or inactive.

The first part of the Alerts screen contains alert actions for all alerts, called Global Actions. If an alert is configured with the Use Global Actions option unselected, then the global actions do not apply. 

Global Active Actions define actions when an alert becomes active. Similarly, Global Inactive Actions define actions when an alert becomes inactive. You can select any of the following options: 

  • Display Notification. You will see a Warning message if you select this option and notifications have not been enabled for the OBDLink app. Open the Settings menu for your device and turn on App Notifications for the OBDLink app.
  • Dialog (Display dialog or Close dialog). Alert dialogs will be closed automatically after 10 seconds if they are not dismissed.
  • Vibrate. Your device vibrates when the alert becomes active or inactive.
  • Speak. Navigate to Settings > Preferences > Speech to configure options. See Configure speech options for details.
    Note: If your device is in silent mode, the alert may not be played.
  • Play Sound. Your device plays a 2-note high-low sound when the alert becomes active. It plays a 2-note low-high sound when the alert becomes inactive.
    Note: If your device is paired with the vehicle Bluetooth, you may not hear the sound, unless the vehicle audio source is set to Bluetooth.
  • Add Trip Event. Navigate to Settings > Preferences > General to enable Record Trip Events

Note: If you select more than one action that produces sound (such as Speak and Play Sound), the actions may interrupt each other. We recommend you select only one Global Action that produces sound.


Configure alerts

Before you begin, be sure to:

  • Start your vehicle.
  • On your phone/tablet, open the OBDLink app and connect to your OBDLink adapter.
  • Make sure your phone/tablet is not streaming to any other Bluetooth/BLE devices.
  1. Confirm that your phone/tablet is Connected to the OBDLink adapter and tap the Settings icon.

  4. Choose the Global Actions you want from the displayed lists.

    Global Active Actions define actions when an alert becomes active (when the PID value matches the threshold setting). Similarly, Global Inactive Actions define actions when an alert becomes inactive. You can select one or more of the following action options:

    • Display Notification. You will see a Warning message if you select this option and notifications have not been enabled for the OBDLink app. Open the Settings menu for your device and turn on App Notifications for the OBDLink app.

    • Dialog (Display dialog or Close dialog). Alert dialogs will be closed automatically after 10 seconds if they are not dismissed.

    • Vibrate.

    • Speak. Navigate to Settings > Preferences > Speech to configure options. See Configure speech options in this article for details.
      Note: If your device is in silent mode, the alert may not be played.

    • Play Sound

      Note: If your device is paired with the vehicle Bluetooth, you may not hear the sound, unless the vehicle audio source is set to Bluetooth.

    • Add Trip Event. Navigate to Settings > Preferences > General to enable Record Trip Events. See the Get Started with Trips article for more details.

      If you are disconnected, you can tap the Test button to verify the alert behavior.
      Note: If you are Connected, you can’t test alerts and you will see the Error message below. You must disconnect your device from your OBDLink adapter to test alerts.

    3. In the Select PIDs menu, find the PID you want by tapping the category or by typing the PID name in the search field. You will see different PID groups depending on your vehicle, your adapter model, and if you’ve purchased any OEM add-ons. You can select one of the default SAE PIDs, such as Engine Coolant temperature or a user-defined PID if you have set one up.
      In this example, we tapped SAE PIDs and selected Engine coolant temperature ℉.

    5. You will see the Alert configuration screen, which contains these options: 

      Settings displays whether or not the alert is Enabled.

      PID shows which Parameter ID is used for the alert.

      Threshold sets the comparison type and the PID value used to make the alert active or inactive. 

      Active Actions and Inactive Actions have Use Global Actions enabled by default. 


      In our example, we want the alert to be active when the Engine Coolant Temperature is greater than 150 ℉. 

      Note: We recommend that you add alerts for exceptional conditions and not for normal vehicle operation. This example is for demonstration only.

Troubleshooting

  • We recommend that you add alerts for exceptional conditions and not for normal vehicle operation. The example in this article is for demonstration only.
  • Each alert requires the OBDLink app to continuously monitor the selected PID. This can impact the refresh rate of other PIDs being monitored. 
  • If you enable one or more actions that produces sound, be aware of these items:
    • If your device is in silent mode, the alert may not be played.
    • If your device is paired with the vehicle Bluetooth, you may not hear the sound, unless the vehicle audio source is set to Bluetooth.
    • If you select more than one action that produces sound (such as Speak and Play Sound), the actions may interrupt each other. We recommend you select only one Global Action that produces sound. 
  • If you select Display Notification in the alert actions, you will see a Warning message if you have not enabled notifications for the OBDLink app. Open the Settings menu for your device and turn on App Notifications for the OBDLink app.
    Tap OK to close the Warning message.
    iOS Preferences screen showing a Warning message. The OK button is highlighted.Android Preferences screen showing a Warning message. The OK button is highlighted.

  • If you tap Test when viewing Global Actions and your device is Connected to your OBDLink adapter, you will see the Error message below. You must disconnect your device from your OBDLink adapter to test alerts.

    Tap OK to close the Error message.
