Control Module Configuration (Initialization Setting)

CAUTION:

If the configuration procedure is not completed correctly after replacing a control module in which configuration is required, the system will not operate normally. Therefore, perform the work in accordance with the replacement procedure in the service information.

If the control module is replaced, and depending on the control module, it may be necessary to write the vehicle specification data to the new control module using the M-MDS. This procedure is for performing the configuration (initial setting).
There are the following three methods of the configuration procedure for the control module:
- Automatic configuration
  - The main control module (built into instrument cluster) performs configuration of the new control module itself and automatically using the vehicle specification data sent via CAN lines.
- Configuration based on vehicle information read/write data
  - Reads the vehicle information from the control module prior to replacement, and writes the vehicle information to a new control module.
- Configuration by As-Built data:
  - Obtains the vehicle specification data when the vehicle is shipped from the factory, and writes the data to a new control module.
  - The configuration using As-Built data is used if the vehicle information cannot be read due to a damaged control module which is to be replaced, or if a DTC such as a configuration malfunction is detected.
  - If a control module having personalization features is configured using As-Built data, the settings personalized by the customer are initialized (to factory settings). In this case, verify the setting values made by the customer and change the personalized setting values using the "Programmable Parameters" from the M-MDS menu.
If the module programming menu of the M-MDS (Programmable Module Installation, As-Built, Programmable Parameters) is performed, perform the procedure while the battery monitor icon of the M-MDS is green or gray.
