ABS unavailable Mercedes

Remember, even though you're getting the abs currently unavailable Mercedes light, the repair steps we show you here on this Mercedes (W204) C250, will still apply if you have an abs unavailable ford or if your abs check engine light stays on with other brands of cars like Toyota, Ford, Honda, etc. Once your abs check engine light turns on and stays on, you need to get an OBDII reader scan tool to plug into your OBDII connector under your driver's side dashboard and read out the check engine light codes. The scanner talks to your car's computer ECU and reads out the check engine fault codes that set off the check engine light to begin with.

C0034 engine code

Once you read out the code the abs light fix is as simple as determining what the engine fault code is telling us. In this video the C0034 engine code simply means that the front right ABS wheel speed sensor is out. This is a sensor that plugs onto the inside hub of the wheel, supplying wheel speed to the car's computer. When this ABS brakes sensor fails, the system cannot figure out how to best apply the ABS brakes, so it turns on the abs check engine light, and gives up, saying that ABS is unavailable. Now you have to fix the error message and clear that C0034 code root cause for good.
