Hello People,

I am in the progress of upgrading my BCM from 86 to 89, i have replaced the BCM and coded then i noticed whichever is related to LIN bus is not working
such as Door controls, Steering switch etc. Cluster rewiring is still pending, is that a reason or what would be the issue..if i replace 86 back then it works fine.

impossible to say just by your post. scan please before and after.

Hey Iichel,

Thanks for replying to this post. I have figured out the issue the BCM i got from the vendor was faulty after replacing another one it works finr
