Mercedes Seat Belt Buckle Troubleshoot & Replacement – Safety First (C230, C240, C280, CLK550)

►Shop the Products used:

Do you have an SRS light on your 2003-2007 C-Class or CLK Mercedes? Rather than taking the car to the dealer, consider replacing the seat belt buckle first or scanning the car for any fault codes. In Mercedes coupes like the Project CLK550, the wiring for the seat belts is often damaged by the repetitive folding motion when passengers are entering and exiting the rear of the vehicle. This can cause a short in the circuit.

Kyle is here to show you how to replace the faulty seat belt buckle on your Mercedes. This video is applicable to all CLK and most C-Class models between 2003-2007.

What is the proper placement?

Ok folks. All of the so called experts are not giving away their secrets, so I will. The gentleman on this video does a great job, but he is missing the root of the problem. This SRS repair light fix is with all Mercedes. Listen up… Put the Mercedes diagnostic on the OBD2. When you get a shorted squib error ( resistance = 0 ), it is not because of a bad squib,and it's rare that a fault of a rubbing wire to ground is your problem. The wires are dressed away from the track. Here's the fix: There are two yellow connectors under the driver seat ( and passengers seat ) that control the seat below and Squib ( explosive). Go to the yellow connector that is connected to the squib and disconnect it. The factory has installed a shorting strip inside this connector as a safety precaution, and this strip is causing the sort. You can fix this one two ways. You can pry this metal piece out or you can eliminate this connector all together by hard wiring. The resistance on the squib is 3.2 to 4 ohms. Remember this is an explosive, and I don't recommend putting a VOM meter on the two squib wires. As a quick test, disconnect the two wires to the squib and short out with a 3 ohm resistor. Your srs light will go away, but the squib is no longer in the circuit, which I don't recommend. The problem is in the connector and the error code is R12/9. You will need to reset the srs light with ICarsoftMBII and the problem will not happen again. If you plan on reusing the yellow connector, you must remove the metal grounding bar, or just cut it off. I hope I was able to save people headaches and money on this fix.

Do you have a video on (2005 Clk 320) Belt buckle airbag, extensioner retractor front passenger failure? I have the ICarsoft CR pro, which is showing me a failure there.
