2003 Mini Cooper Base, Automatic CVTFACTORY OEM SERVICE PROCEDURE

What is Coding?

It is a process utilized by MINI, which groups system specific operating requirements (Data) together and then assigns a label/code to each of these groups of data. The various groups of data are all pre-loaded into system specific "codable" control modules, along with a basic set of operating instructions (Program).

Types of operating requirements:

  • Nominal values of device input signals (0.25V to 2.5V, 5W - 25W,...)
  • Type of device input signal (PWM, square wave, analog ...)
  • Operational parameters (device activation/deactivation time,...)
  • Market specific operations (O2 Sensors, Fuel Type, Emission Control,...)
  • Country Specific Regulations (U.S., Canada, Japan, UK, ECE,...)
  • Powertrain Configurations (Manual, Auto, Diesel,...)

The procedure of assigning one specifically labeled group of data to the operating program of a specific control module/component is referred to as "coding".

A "codable" control module has a basic operating program already installed along with several specific variations of operating data. The coding process allows a specific set of operating data to be assigned to the basic operating program of that module/component, with respect to its specific application.

Coding can be performed for some systems/components:

  • Selecting customer specific system operational settings from a list of available features (VKM)
  • Automatically by selecting a specific coding process available via ZCS Coding or CIP using the DISplus/GT1/SSS.
  • By using a coded ground wire to a module.
  • Determined at the factory.
NOTE: Codable control modules/components are system specific, which means that not all control modules are codable.
