Control Unit Coding
Control unit coding sets options in a control unit so it matches the vehicle equipment.
What is Control Unit Coding?
It is needed after replacing many modules. It enables or disables features. It is different from reprogramming software. Examples include matching a new module to tyre size, lighting type or country version. Many workshops use manufacturer tools or advanced scan tools for coding.
How it works
Coding writes configuration values to the module memory.
Why it matters for your car
Wrong coding causes faults or missing functions. Save the original coding before changes.
