I’m encountering a frustrating problem with my new Android car stereo and OBD2 adapter setup, and I’m hoping someone can offer some guidance. I recently installed an Android car stereo and want to use the Torque app with a Bluetooth OBD2 adapter for vehicle diagnostics. The adapter itself seems to be getting power, as indicated by the red LED being lit. My Android car stereo also recognizes and connects to the Bluetooth OBD2 adapter in its Bluetooth settings.
However, when I launch the Torque app, it fails to establish a connection to the car’s computer (PCM) and doesn’t recognize the car’s protocol. To rule out a faulty adapter, I tested it on two different cars belonging to friends, using my car stereo, and it worked perfectly in both cases. This leads me to believe the issue is specific to my car. I even tried using an Android phone with the adapter in my car, and the problem persisted, further suggesting the issue isn’t with the car stereo or the Torque app itself, but rather something within my vehicle.
Online research pointed towards a potential problem with the cigar lighter fuse, specifically fuse #13 in the front fuse box. I checked this fuse with a tester, and it appears to be in good working order. Interestingly, during the car stereo installation, the technician mentioned that my cigar lighter was not functioning – it’s not receiving power. The adjacent 12V power outlet, however, is working correctly.
Could this non-functional cigar lighter be related to my inability to connect the Torque Bluetooth Obd2 Adapter? What steps should I take to get my adapter working? Any help or suggestions would be greatly appreciated.
I am using this Vgate Bluetooth OBD2 adapter:
In the Torque app, the Bluetooth adapter icon is solid, indicating a connection to the adapter, but the car icon continues to flash or blink, signaling a failure to connect to the vehicle’s computer.
