Programming control module

Applies to MY 2005-
After downloading and configuring the control module the control module receives the vehicle configuration data from the central electronic module (CEM). This can take up to 15 seconds and during this time the SRS lamp flashes in the Driver information module (DIM). Downloading and configuration is complete when the SRS lamp stops flashing.
