The Capabilities of J2534 and CarDAQ-M
The CarDAQ-M is the most complete J2534 pass-thru device available
today. The capabilities of CarDAQ-M are largely determined by software
the vehicle manufacturers provide. More information on specific
manufacturers can be found in the J2534 Toolbox.
Reprogramming with J2534
J2534 and federal law mandate that automakers allow shop technicians
the ability to re-flash emissions-related vehicle electronic control units,
typically engine and transmission controllers. Some automakers allow for
more modules, and some have enabled factory diagnostics. Use the J2534
Toolbox for more information on the capability provided from each
manufacturer.
