Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Climate control module (CCM)
Climate control module (CCM) (3/112) receives the signals from the switches furthest down on the dashboard environment panel (7 in a row). Located here amongst other things are switches for private locking, child safety locks and reduced alarm.
The switches may be arranged in a different order from the one shown in the illustration depending on the vehicle's configuration and equipment.
When one of the switches is pressed the climate control module (CCM) sends a request over the CAN network to the rear electronic module (REM) that the corresponding function is activated or deactivated.
The climate control module (CCM) communicates with the rear electronic module (REM) via the low-speed side of the CAN network.
