MUSTER Posted June 13 Report Share Posted June 13 Hi, I am fine tuning the starting configuration on my ECU, but so far I have not been able to connect the CANBUS port to my AEM X30-3000 Lambda probe. I'm going to explain how I do it, in case I might have made a mistake. I look forward to your help on this matter. I have connected the CANJST cable (SN 101-0197) to the CAN1/RS232 port of the ECU. Then I feed the RED/BLACK wires with +12v/Chassis Ground respectivly and the AEM (Green/White wires to Green w/ black strips and White w/ black strips) througt a DTM4 connector with white (CANH) and Green (CANL) to the ECU port, but the ECU dont detect the CANBUS Connection. It will be I need a terminal 120ohm resistence before the AEM lambda connector? or Maybe I made some wiring or configuration mistake? How CAn I probe it? Now I can read the parameters through the analog cables (0-5v), but I know it is not the best option.... Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 13 Report Share Posted June 13 Your wiring sounds ok. In a perfect world you should have a 120ohm terminating resistor near the AEM device, but that is unlikely your problem, I have seen many used successfully with no termination before. So I think possibly an issue with your software config. Attach your map and one of us will take a look. Quote Link to comment Share on other sites More sharing options...
