Hi All,

I have a project which requires continuity check of two sensors attached with BMW control unit. I tried using weidmuller (MOS 5VTTL/24VDC 0,1A)micro opto solid state relay but its not working. My best guess is that the data transmitted is some kind of serial number which needs to be decoded. I have not done this kind of work before so please can someone help me out with this? Any kind of help will be appreciated.

The model number of control unit is 61 35 7498464. There are two sensors attached with control which are having model number 7543312-02.

I have also attached picture of whole assembly just to make it more clear and simple.
