Understanding the difference between automotive programming and coding

In this Motor Age Tech Tips video, training specialist and consultant Andy Tirado explores the key differences between automotive programming and coding, two commonly confused terms in the automotive repair and diagnostics world. With the help of the Autel 909  scan tool, Tirado walks through real-world examples of how technicians interact with vehicle control modules, highlighting functions like start-stop comfort parameter adjustment, transmission adaptation, and HVAC sensitivity settings.

He explains that coding involves changing allowed parameters within existing software — such as enabling seat heaters or adjusting idle RPM — while programming refers to installing or updating software on a blank or existing module, often using J2534 programming standards. Tirado also introduces the remote expert vehicle programming option, which allows shops to access OEM-level programming remotely, saving time and effort.

Throughout the walkthrough, Tirado shows how to navigate different modules, perform adaptations, and make changes that enhance vehicle performance or meet customer preferences.
