Scott3 Posted October 29, 2023 Report Share Posted October 29, 2023 Hi i have a installed a link pdm and having trouble getting the pdm to see the keypad? is a resistor required in the can wiring between the pdm and keypad Quote Link to comment Share on other sites More sharing options...
aerace_fab Posted October 29, 2023 Report Share Posted October 29, 2023 Is your pdm paired with a Link ecu? If so the ecu has a 120ohm resistor on board, the pdm has a selectable resistor on board which you can toggle on/off. If not then you will need to have a 120 ohm resistor at the end of the CAN bus line. Quote Link to comment Share on other sites More sharing options...
Scott3 Posted October 29, 2023 Author Report Share Posted October 29, 2023 no iam not using a link ecu just the pdm and keypad ? so i need a 120 ohm resistor at the keypad end of the can network ? Quote Link to comment Share on other sites More sharing options...

Can you attach a copy of your PDM config. Is it a Link keypad? Quote Link to comment Share on other sites More sharing options...
