2389053301 Mercedes W205 W213 C238 Rear Switch Module – OEM Used & Tested

Descriere

This Mercedes rear switch module is a genuine OEM electronic component for the Mercedes W205 C-Class, the W213 E-Class and the C238 coupe. Primary OEM number 2389053301. It is designed to read the rear switch inputs and to pass the commands over the vehicle data network to the connected rear comfort and convenience functions.

Its job is to detect when a rear switch is pressed, convert the input into a data message and send it to the control units that carry out the requested function. A properly working rear switch module supports convenient operation of the rear functions by the passengers, reliable communication with the other control units and correct operation of the comfort system of these models.

Common signs of a faulty unit include rear switches that no longer react, functions that work only sometimes, switch backlighting that is dead, warning messages related to the comfort system, or stored communication fault codes for the module. Because the module sits in a convenience circuit, a faulty connector or damaged wiring can cause similar symptoms, so these should be checked as well. When the module fails, the rear functions may stop responding.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2389053301 before ordering and compare it with the label of your unit. Professional installation is recommended, and a diagnostic scan, a check of the connectors and wiring and coding or adaptation to the vehicle where applicable should follow installation.
