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.
