RexG Posted December 27, 2019 Share Posted December 27, 2019 Have just tried to use PCMTec for the first time and I am having some trouble. Using Tactrix Openport 2.0, trying to read stock tune off an 03 BA XR6T It keeps coming up with the error message Error Reading Flash due to UDS error: Sent Cmd:READ_MEMORY_BY_ADDRESS Received: SECURITY_ACCESS_DENIED I've tried searching the forums but can't find this particular problem anywhere else Error message doesn't come up until after it tries searching for a ZF TCM It can detect the PCM and retrieve the type and VIN, and the datalogger works too but I can't read the tune off the PCM Thanks for any help Quote Link to comment Share on other sites More sharing options...
RexG Posted December 27, 2019 Author Share Posted December 27, 2019 Problem solved by unselecting "Read/write TCM" Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted December 28, 2019 Share Posted December 28, 2019 If you download the 1.22 beta it should automatically deselect the ZF read for a BA now. Quote Link to comment Share on other sites More sharing options...
