4.2. Bluetooth Connection Problems

Problem: My phone cannot locate the Bluetooth signal.

Answer: The first check is to make sure that the OBD reader is powering on. If it is, you will want to then unpair ALL Bluetooth devices from your phone, restart the phone and try again. Sometimes phones can become glitchy or buggy and this will normally resolve the issue.

4.3. Check Engine Light Issues

Problem: I tell Torque to clear the check engine light but the light remains on.

Answer: When this occurs the first thing to do is try clearing it with the vehicle fully running and if that fails, also try clearing it with the vehicle in ACC mode but not running. Please note, some codes are “instant” meaning as soon as they are cleared, if the problem causing them is not fixed, the light will come back on immediately. In such case you will never see the light turn off.

4.4. Reading Other Vehicle Systems

Problem: The OBD reader is not reading my ABS, SRS, VSC, Oil Change, or Maintenance lights. What gives?

Answer: This being an OBDII reader it can only read and dear your check engine light. It cannot assist in reading or clearing lights related to any other vehicle system. For these lights, you will need to use a different tool or in some cases take the vehicle to a repair shop.

4.5. App Connection Problems

Problem: I completed the setup steps but the app says it cannot find the adapter OR the app states it cannot connect to the vehicle OR I am having problems connecting to the OBD reader via Bluetooth.

Answer: All of these problems are, most limes, caused by a glitch in the phone or app and can normally be fixed with low easy steps. When all else fails, please complete the steps below EXACTLY as written and in the order, they are written:

Close ALL apps that are open on your phone
Unpair ANY and ALL Bluetooth devices from the phone
Shutdown the phone completely
After a15 seconds, turn your phone back on
