dale.a Posted November 28, 2022 Report Share Posted November 28, 2022 Hi, Trying to connect my link g4+ xtreme to my powertunedigital display and having trouble with the can not sending it any data. These are the faults I have and testing the volt on the low and hi pin outs I am getting 2.47 steady on both. Cheers Quote Link to comment Share on other sites More sharing options...
Confused Posted November 28, 2022 Report Share Posted November 28, 2022 I'd say either CAN H and L are reversed, or there's a bitrate mismatch between devices on the bus. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 28, 2022 Report Share Posted November 28, 2022 The ECU has to stop broadcasting messages when the transmit error counter reaches 255, this will give the "Bus off" error. So that explains why no data, but that is not the root cause of the problem. As Confuse suggests you likely have a wiring or set up issue.

dale.a Posted November 28, 2022 Author Report Share Posted November 28, 2022 I have tried both reversing the wiring on the can connection and i have taken readings directly from the pins on the board and i am still getting the same 2.5v reading. could this be because of the error counter reaching 255? i have the bitrate set to 1mbp/s on the powertunedigital display which should match the link. cheers Quote Link to comment Share on other sites More sharing options...
