C249C Trouble code
I had my 03 R230 give the visit workshop for brake system alert. I put my Icarsoft on it and received a C249C code - Test cable stop lamp to N10/11 passenger side SAM control Module for Voltage.
Any help on how to do this is appreciated

I Googled "Mercedes code c249c" and see similar solutions. The AI summary is:
Mercedes code C249C is a fault code related to the SBC (SBC stands for Servobremse or Brake Assist System) and typically indicates an issue with the brake pedal switch. The most common cause is worn contacts in the stop lamp switch, which can cause a delay in switching between the two sets of contacts. Replacing the brake pedal switch is often the recommended solution.

SBC stands for Sensotronic Brake Control.
There's a known issue with water ingress into the SAMs - especially the RHS one.
Pull the SAM and look for any corrosion in there. While you're at it, check your two drain tubes under the hood. They clog up and water gets into the module.
