Reading mode $06 data from LS1 style controller

[DS106Q]

Hello all!

I'm tyring to manually read mode 06 data from a LS1 sytle controller (J1850 VPW protocol).

I can send (hex) 68,6A,F1,01,[PID #] to request a mode 01 PID value, but how do I request a specific mode 06 test & component ID? Specifically, I'm trying the read the vale of test ID 02, component ID 66.

I'm assuming it's not as simple as a slight modification of the generic 68 6A command above, but instead will require a 6C 10 style command, but no matter what I try I don't get a response (or at least, not a valid one).

Turns out you did have your coffee, or just don't need it! What you wrote, as one can expect is, the correct command. At the time I made the original post, I didn't realize the ELM interface wasn't actually sending commands on the bus. This (and the fix) is detailed in my ELM monitoring thread, but figured I would provide an update here in case anyone else wants the command.

All mode 6 queries for a specific test ID result responded back with every component in that test ID. In my request for TID 02, the response included all 11 CIDs for my vehicle.
