Vaughan Posted July 18 Report Share Posted July 18 If it's the same keypad as in your other post then it is because it is a J1939 keypad not a CAN Open keypad. Quote Link to comment Share on other sites More sharing options...

Adamw Posted July 18 Report Share Posted July 18 Ok, so do you have a CANopen keypad now? Is it a generic Grayhill or from another ECU brand? Anthony777 1 Quote Link to comment Share on other sites More sharing options...

Vaughan Posted July 19 Report Share Posted July 19 The grayhill keypad is set to 250kbp/s by default, so remove devices from the CAN bus other than the ECU and Keypad, change the ECU CAN bus rate to 250kbp/s remembering to click apply and then do the find devices search, once you have found it change it's bus rate to your preferred rate and also use the send default comms setup button.

When I disconnect my dash the ecu disconnects for some reason Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 19 Report Share Posted July 19 That would probably suggest you have a wiring issue too then. Leave the dash disconnected for now so you can diagnose what is causing the ecu connection problem. Most likely the ecu is missing its power supply or similar.
