The Programming and Coding function is used to re-flash the vehicle control
modules, it allows you to update the computer software on the vehicle to the
latest version, as well as to reprogram adaptive data for certain components
after making repairs or replacements.
NOTE: The programming function can only be applied through connection
with the J2534 programming device, which serves as a PassThru interface to
establish communication with and transfer data to the vehicle’s ECU.
Available programming or coding operations vary be the test vehicle, and only
the available operations display in the menu.
There are two general types of programming operations:
A. Adaptation Operation – also known as Teach-in Program, Control Unit
Adaptation, Variant Coding or something similar, is used to reprogram
adaptive data for vehicle control modules after repairs or replacements of
vehicle parts.
B. Reprogramming Operations – downloads new version of software
subscription from the on-line server database through internet access
(this procedure is done automatically when the MaxiSys display tablet is
connected to the internet, so there is no need to check for software
subscriptions yourself), and reprograms the newest software version to
the vehicle’s ECU.
Selecting the Programming or Coding function opens a menu of operation
options that varies by make and model. Selecting a menu option either shows
a programming interface or opens another menu of additional choices. Follow
all screen instructions while performing the programming operations. How and
what information is presented on the screen varies according to the type of
operation being performed.
