Monitoring the DTC occurrence counts with UDS

[alper]

Hello,

I want to monitor the occurrence counts of DTCs and show them in the diagnostic application that I developed with C# and PCAN-UDS API.

According to section 3.6.49 of PCAN-UDS API documentation; SvcReadDTCInformationNoParam service may provide this, but it seems there is not any parameter listed for reportDTCFaultDetectionCounter sub-function.

Could you please help me, how can i read occurrence counts of DTCs with UDS/PCAN API?

Best Regards.

Hello alper,

Please update your PCAN-UDS API to 1.3.3.50 (https://www.peak-system.com/PCAN-UDS-AP ... .html?&L=1), an update was released in June that adds that missing parameter:

2019-06-27 - Version 1.3.3
* Improvements:

• Certificate checking of the libraries improved. In some special environments the initialization process of a channel could last about 20 seconds

* Bug fixes:

• Fixed problems with Endianness conversions
  The following missing RDTCI definitions have been added which are now supported by the UDS_SvcReadDTCInformationNoParam function:
  • PUDS_SVC_PARAM_RDTCI_RDTCFDC
    PUDS_SVC_PARAM_RDTCI_RDTCWPS
