That one has a "bad checksum", so Hijack ignored it.

It gives me nothing on the Hijack Button Codes display.

Yeah, 0xff is the *only* stalk report that Hijack does NOT show on the front panel, because it means "button released"

So what you got was a 0x00 "button pressed (but bad checksum)", followed by a "button released".


Mmm.. a correction on that. I misread the packets. The checksum is likely passing just fine after all. The button value isn't 0x00, but rather 0xff on both packets. So it really is invalid, and quite likely a circuit issue in the tuner.

I wonder if the in-car stalk somehow damaged the tuner's stalk input? We already know there's more in there than just a resistor array (because most buttons generate a pulse, rather than just a continuous level).
