I did try the g4+ software aswell still didn’t work, However I tried it when it was unplugged from the car - stupid question, are you able to connect to the ecu when it’s not connected to the car?

curly Posted December 29, 2023 Report Share Posted December 29, 2023 No, the ecu needs to be powered. Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 29, 2023 Report Share Posted December 29, 2023 When connected to the car with ignition on, check the blue LED lights up to indicate it is powered. Quote Link to comment Share on other sites More sharing options...

Georges Posted December 30, 2023 Author Report Share Posted December 30, 2023 I have also tried probing 12v + and ground the TVS diode and no lights Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 30, 2023 Report Share Posted December 30, 2023 When fitted in the car with ignition on, do you have 12V on pin 67 and Gnd on pin 25? You can access these pins at the back of the grey connector on the ecu. Quote Link to comment Share on other sites More sharing options...

Adamw Posted January 1 Report Share Posted January 1 I think there must be something faulty or damaged with the ecu in that case, you will have to contact [email protected] and get it inspected. Quote Link to comment Share on other sites More sharing options...
koracing Posted January 3 Report Share Posted January 3 Was the ecu purchased new from a Link dealer? It looks like a G4+ bottom board with a G4x top board on it... Quote Link to comment Share on other sites More sharing options...
