Ok, one more way of trying to get to the answer of my dilemma.
When properly connected to the OBD connector on a modern day vehicle that has CAN, with correct baud rate selected, all hardware functioning correctly, and all wiring correct, using MAX and the NI-CAN Bus Monitor, ignition key on or in the run position, what would be the reason I don't see any bus traffic displayed? Thanks!
If ADCS is working and the bus montitor without ADCS is not working I assume that the ECU is not sending any frames on the bus without a request message.
Take a look at "Gibson" answer message 17 again, please.
You can verfiy this if you starts the Bus monitor and go to the " frame send" page (STRG +T).
On this page define a CAN request message and send this message to the ECU.
If you get a response from the ECU you know that your setting is correct and that the ECU always expected a request and you have no traffic on the bus without a request message.
Hope this helps.
