zaihas.chan Posted May 17, 2023 Report Share Posted May 17, 2023 Hi, Im working on some project and need to send the fault code from ecu to my microcontroller via CAN bus. For the case where the fault codes count is more than 1, how do i send all the fault codes to via CAN? From the help file - the "Fault Codes (Status)" defined as per below: Is it if i set the parameter in the frame to "Fault Codes (Status)", which the data will be 0-255: Is it representing then number of specific fault code i.e Fault code 57 --> MAP Above Fault Code Value OR is it bit position of the fault code. means bit 57 in fault code is MAP Above Fault Code Value Thank you in advance!!!

Adamw Posted May 17, 2023 Report Share Posted May 17, 2023 Multiple fault codes will be sent out individually for about 2 secs each. If you look at the Y axis of this plot that would be the value sent in the byte. Quote Link to comment Share on other sites More sharing options...
