What is the “Front Right Malfunction Service Required” message?

If you see the error message on your instrument cluster, you should check for malfunction within the Supplemental Restraint System (SRS).

The Supplemental Restraint System (SRS) checks the operation of several individual components in your Mercedes including the airbag, airbag control unit, crash sensors, emergency tensioning devices, belt force limiters, and more.

Where one of these components is faulty, you will notice the SRS warning light on the cluster dashboard screen, along with other signs.

In the case of the “Front Right” our focus is on the front passenger, which will include all SRS components on the front passenger side.

Remedies for the Front Right Malfunction Service Required

Our remedy for this code focuses on wiring connections and issues. In cases where a physical inspection reveals a faulty component, replace damaged components.

We begin our fix from the airbag control unit. You can find its location on the schematic diagram of the car’s electrical system. (See N2/10, plug 1).

Firstly, disconnect the 104-pin attached to the airbag control unit. Remove the fastener or cable tie from the housing of the disconnected coupling.

Also, gently untie the fabric wrap on all the lines of the plug collar. Now fasten the wiring harness using a new cable tie. Reconnect the 104-pin coupling to the airbag control unit.

Furthermore, inspect the wiring connection of the 20-pin coupling of the airbag control unit (see N2/10, plug 2). It is a sub-harness of the 104-pin coupling of the airbag control unit.

Fasten the harness of the 20-pin using and all other connections using a felt strip.

If you still see the error message or any of the related trouble codes, proceed to clear the code using an OBD II scan tool.
