Fotis Posted October 5, 2020 Report Share Posted October 5, 2020 I have a customer with a Pnp G4X HC96 ecu. Today i plugged the usb port into the laptop and it shorted out my laptop port. Then i changed the usb cord and picked another laptop and it shorted out again. Measured voltage on the usb coming from the ecu is 12V. Anyone knows whats up here? Not the first time powering up the ecu. It was tuned from me the very first time. Quote Link to comment Share on other sites More sharing options...
0x33 Posted October 5, 2020 Report Share Posted October 5, 2020 Check your USB connector is not plugged into the CAN port on the board of the ECU. This will cause a short on laptop. Fotis 1 Quote Link to comment Share on other sites More sharing options...
Fotis Posted October 5, 2020 Author Report Share Posted October 5, 2020 Will check it but am quite sure in the first place it was okay. I don't thing the customer changed the plug to the can. But will check it for sure Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 6, 2020 Report Share Posted October 6, 2020 Only CAN2 port has 12V on it so you must have the USB cable plugged into the CAN2 port. The USB port is quite clear, it is on the underside of the top board and there is a big arrow pointing at it. Fotis 1 Quote Link to comment Share on other sites More sharing options...
