NOTE:
The illustration above and the table below is an example that shows model year 2007. All other information in the document is general and applies to all model years.
| Control module | Name/ Function | Connected to/Master node | Other |
| ACM | Alternator control module (ACM) Controls charge regulation of the battery. |
Engine control module (ECM). Also diagnosed by the Central electronic module (CEM). |
|
| AQS | Air quality sensor (AQS) Measures the particle content in the air into the climate system. |
Climate control module (CCM) | The Climate control module (CCM) uses this signal as a basis for control of the damper for recirculation. |
| CPM | Combustion preheater module (CPM) Petrol driven engine and passenger compartment heater. |
Central electronic module (CEM) | |
| DMM | Damper motor module (DMM) Regulates the air flow in the passenger compartment, temperature between the right and left sides as well as recirculation. |
Climate control module (CCM) | The number of damper motors varies depending on the equipment level and whether the vehicle is right or left hand drive. |
| GSM | Gear selector module (GSM) Provides input signals to the Transmission control module (TCM), about the position of the gear shift. |

| ISM | Inclination sensor module (ISM) Detects changes to the vehicle incline when the alarm is activated. |
Rear electronic module (REM) | |
| LCM | Left camera module (LCM) | Driver door module (DDM) or Passenger door module (PDM) depending on whether the vehicle is right or left hand drive. | Component in the BLIS system. |
| LSM | Light switch module (LSM) Sends signals to the Central electronic module (CEM) concerning settings for the exterior and instrument lighting. |
Central electronic module (CEM) | |
| OWS | Occupant weight sensor (OWS) Used as an input signal to indicate deactivation of the front passenger airbag. |
Supplemental restraint system module (SRS) | |
| RCM | Right camera module (RCM) | Driver door module (DDM) or Passenger door module (PDM) depending on whether the vehicle is right or left hand drive. | Component in the BLIS system. |
| RSM | Rain sensor module (RSM) Detects whether there is water on the windscreen. |
Upper electronic module (UEM) | Used to control the automatic wiper function. |
| SCM | Siren control module (SCM) Controls the siren function. |
