Parameter output setting

most outputs from the ECU are Low Side Drives, meaning they are ground when you turn them on and open when you turn them off. (there are exceptions, but A15 and A20 are LSDs)

Cars Stalls When Clearing Code and Code 10 IAT

that feature has slowly propagated through the OEM's.
I wasn't sure if Honda adopted it yet or not, last I checked it wasn't blocked, but it's been a few years.
Glad to hear that they updated.
