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).
