OBD Request Emission Related DTC During Current Drive Cycle

[BiPa]

Hello LabVIEW Engineers!

Software: LabView 8.5.1 and Automotive Diagnostic Command Toolset 1.0.1.

Hardware: PCMCIA-CAN Series 2 / NI-CAN 2.5.2f

I am trying to read the Emission Related DTC's for the current Drive Cycle   ( Mode 7 ) with LabView. Unfortunately the VI only reads 2 DTC's. With a  OBD Scan Tool  I can read 7 DTC's from my ECU. I am getting this error code from LabVIEW: - 8261 ISOTP Receive.vi

What does this error mean? 

 

Did anybody already tried reading these DTC's?

Thx

Dear BiPa,

this error indicates a timeout when receiving long diag frames. To solve it increase the timeout Timeout CF (Cr) (e.g. to 2000ms) with the Diag Set Property.vi (cp. screenshot).
