Anyone know of a good independent shop that has the tools and knowledge to do a WSS calibration in the central Florida area. I have a 2009 ML350 (164) that I have an error code 9A14. Component WSS is incorrectly adjusted.

 

Before you bring your car for repair, remove the dust cap and check for dust. Read the PDF carefully.

 

Thanks Maj.

Just a little history on how I got here.

A few weeks ago I replaced the battery. I think I must have caused a problem with the WSS then. After replacing the battery I got the SRS fault. I checked with my scanner and found a fault code 9A07 B48/14 right rear sensor has an open circuit in the wiring. I thought I might have cut a wire moving the seat up and forward to take out the battery. I looked and looked but could not see any problem. I decided to take it to the MB dealership. They did a scan and told me that they would have to replace the the seat base frame. Cost $3400.00. I told them they should look for a open circuit to the right rear sensor B48/14. And if needed replace the sensor and re-calibrate the WSS. They told me that, that is not what MB recommends. I told them that they where nuts. That they should be at least able to replace the sensor and re-calibrate the WSS. He asked me give him a few minutes he would check with their parts manager. Later he told me that they could do that for $1400.00 with no guarantee that it would work. At that point I paid for my scan and told them I could not trust anything they said.

the next day I decided to look for an open circuit to B48/14. I unbolted the seat and tried pushing on all connections and looked for any wires that might have been damaged. No luck. I put the seat back and did another scan. I no longer have the open circuit error codes. Now just the code saying the WSS is incorrectly adjusted.

So I think I might need to find someone trustworthy with the right tools and knowledge to do the job.

 

With all your writing you never say that you tried to delete the code.

 

I did try and clear the codes. My scanner is an Icarsoft II.

 

What color wire did you break?

 

I did not find any broken wires.

 

First you got 9A14 and then you got 9A07, please explain.

Did you remove the front seat to replace the battery?

 

First I got 9A07. This after replacing the battery. I did not take the seat out to do this. The dealer may have cleared that code. I did not do a scan again until after I unbolted the seat and looked again for a bad connection. At this point I did a scan and now have the 9A14 code.

 

There has to be a broken wire for this code.

 

Long time passed this post. Just wondering if you managed to get this resolved. I have had this problem, still going on.
