Diagnostics Operations Programming and Coding
48
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 Autel’s 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 by the test vehicle, and only
the available operations display in the menu.
There are two general types of programming operations:
A. Coding – also known as Teach-in Program, Component Adaptation 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.
NOTE: Ensure that the display tablet is connected to the Internet before
applying the ECU programming function, so that the display tablet is able to
obtain access to the manufacturer’s server for update service.
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 or coding operations.
How and what information is presented on the screen varies according to the
type of operation being performed.
