I was asking about the ones that you showed the features on the back of the box and the 3140 says it does ABS and SRS but you’re saying they don’t work for SRS on our trucks, so I was wondering if there’s a disclaimer stating they do work on that function but not on our rigs.
I was referring to wired scanners, those all work as far as I know as long as they have the feature, there is just something about the wireless ones that won't it appears some will read a abs code, if you look at the bluetooth adapters out there most of them use the ELM chipset and there are tons of knockoffs on the market, some will read ford but not gm
