Reading VIN
Posted: Wed Jul 05, 2017 8:31 pm
Hi,
I'm trying to pull the VIN from the OBD-II Emulator MK2. I get no response at all for this request. My code is running on an in-vehicle PC with a dedicated OBD-II SDK. The vendor tells me the problem is the time they pause before sending the next flow control frame. They delay for 400us. In testing they just tried 1.1ms instead, and now it works.
Reading ISO 15765-2, the timeout for N_Bs is 1000ms. Is there a recommended minimum? Can anyone advise?
