Hi!

 

I have trawled the internet for an answer to my query to no avail, so on seeing that this thread was still active I thought I would post!

 

My 55 reg Fiesta Style 3 door (non-face-lift) has its engine light on, of course just as I am coming up to look to sell.

 

My Uncle had an OBD2 bluetooth scanner which he has used on a different car with great success so I tried this on my Fiesta - on plugging it in, all that came on was a red LED (as opposed to the green one which was the case on the other car) and the scanner was undiscoverable via bluetooth. My uncle went away and put some power through the scanner and it came on and worked fine. I later purchased a different brand of scanner and, of course, the same thing happens - all that comes on is the red LED above the "PC" label. I have also tired this scanner on another facelift Fiesta which I think is 57 reg with absolutely no success i.e. the same red LED shows up and the device is not discoverable.

 

Before I fork out either another £15 on an F Super which apparently should work, or take my car down to the local Gates and have them tell me what the problem is for £105(!!!), can anyone tell me why no scanners seem to work with my car?! This is incredibly frustrating as I am sure you can imagine!

 

Thanks

 

Chris

Hi Chris,

 

this is a new one on me! so you have tried the same working adapter on two seperate Fiesta's and they dont work at all? Basically the red light is little more than power, and showing that the car is connected to the bluetooth adapter. The Green light will only come on after you have opened the device via Torque or a similar application.

 

I know that when I first got my mondeo, it seemed impossible to get the devices to work, however, after I left it plugged in for a while, and Torque open on screen (just left it to try and connect) after about 10 - 15 minutes, it just came to life.

 

It might be something similar, Torque will probably be trying to connect not only to the bluetooth, but working out the parameters to communicate with the ECU.

Frustrating that it doesn't even appear on bluetooth when searched on a number of devices. Tomorrow evening I will leave it running/searching for a while and have another go, maybe it just needs a bit of encouragement! Will feed back to see if I get it working.

 

Thanks so far!

No Worries,

 

You might have a faulty adapter. As soon as its connected and the red light comes on the bluetooth module should become visible to all to see. You then pair up with 0000 or 1234 and it goes from there.

 

If your phone isnt even picking up the bluetooth broadcast, it would suggest its not powering up the bluetooth correctly, or its defective in that the power supply its getting from the port is not sufficient to power it correctly.
