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.
