Hi there, my S300 is no longer being detected on my laptop, not either being detected as a new USB device.

It is in a standalone race car which has no factory wiring remaining how ever I put a wiring loom in and have had it connected, powered up, registered and datalogging.

I had tried to connect a rear wheel speed sensor and had the signal wire connected to VSS B10 (YEL/BLK)

I wired it up how via this http://www.xenocron.com/downloads/RaceS ... Sensor.pdf and when using a volt meter on a spare battery I could not get the output wire (BLK) to output ANY voltage - so I'm not sure what has gone wrong.

Could this have damaged the ECU?

I also at one point lost my balance and ended up falling onto the ECU itself, I can't imagine it would have flexed enough to damage anything but thought I would make note of it.

Are there any tests I can do to show if the ECU has been damaged? All voltage inputs on the wiring loom side are working as per normal

I had updated to 2.2.8 and thought that may have caused an issue with USB drivers so went back to 2.2.7 and still no dice

Thanks

What does it show up as in the Windows device manager when you have the key on and plug in the USB?

Nothing, not even the 'bing bong' sound to show a usb device has been connected.

Laptop still detects other usb devices.

Are there anything I can do to diagnose a damaged ecu?

Do any lights come on inside the ECU on the s300 board when the key is turned to the on position?

No lights on the S300 when turned on.

I might put it in my EJ1 to rule out any of my wiring issues

Well I guess I broke a wire somewhere, it works in my EJ1 :)

thanks for your help and sorry for wasting your time!
