Is there any way to test a seat recognition sensor?
I read through a bunch of posts regarding the seat recognition sensor. Most people pay $130, I just got a cost of $250 for a 2002 E430 4MATIC.
I had the prob where the light would go on and off when someone sat in the seat. Took it all apart and found a wire was broke. I fixed that and I am still getting the light. To further complicate things, last ice storm I slid down a driveway and damaged the 3/4 of one side of the car (@ $6K) and so I don't know if I might have tripped a sensor. So the other question is, I ordered an OBDII reader. Will I be able to retrieve the codes for the SRS system with an OBDII reader? Or is there a way to check the seat recognition sensor with a volt/ohm meter to test it to see if its still good? Thanks! |

UNDER $1000.00-$2000.00 OBDII reader. Will not able to retrieve the codes for the SRS system you need SDS to do this job.

Eppy, I had to replace the one in my 2000 E320 and it was no where near $250. I would get a quote from an indie, that's what I did and was able to get one for around $125 if I remember correctly. I plugged the new one in before I installed it and all worked normally. If it didn't fix the problem I could have taken it back but luckily it fixed the problem. If you replace it yourself I can tell you from experience it helps to have another set of hands when you do it. Getting the sensor in place, getting the clips to hook, etc. etc. is really a pain if you are going to do it yourself.
Oh and the OBDII reader will not tell you SRS codes but it sounds like you've got it narrowed down to the problem due to your light going on and off when someone sits in the passenger seat.

I got a price from two different places one of them from here and the price was $250.
That is why I am asking to see if there is a way to test it? I'm pretty sure they sending the whole seat cushion with the sensor in it. Did you get just the sensor or the sensor and leather seat cushion? |

No, they will send you the sensor grid and you have to remove the old one and put the new one in.
The grid lives under the cushion and I have never heard of anyone getting the cushion with the grid, otherwise that would probably cost a grand or so knowing M/B. The job is not bad if you pay attention. It helps to remove the entire seat from the car, then remove the seat back to access the part and flip the seat over and over while fiddling with it. Pay attention to how the wires are routed and you will be pleased how easy it really was to do. If you are halfway descent mechanically, you will do fine. You probably have set a code that will not go away until a SDS is put on it to clear codes. If you repaired a broken wire,and that was the only problem, you may just need the code erased with a laptop. |
