Quoted From EricTheCarGuy:
You could still jump the 2 pin connector and get ‘codes’ all the way up to the mid 2000’s on Honda’s and Acuras. OBDII however only covers emissions and does NOT cover ABS, to this day manufacturers have their own codes for ABS even though you can retrieve many of them with a scanner, it was never mandated that ABS had to be generic like OBDII did for emissions.
Thanks for the tip Eric. I feel like I got ripped off in my brakes class, as our instructor was a ‘fill-in’, and literally spent about 1 hour covering ALL of ABS right before our final exam. I’m looking into sitting in on a class when they cover ABS systems, and I better not get charged…
