Technical Bcm incorrect?

[stew565]

Hi everyone,
I have a 2008 3.0 fiat ducato motorhome.
Clearance light warnings on cluster and buzzer sound . An Auto electrician has told me it has the wrong bcm fitted.
It also has had a new cluster fitted.
My Question is he correct, are they matched and have they been changed.
All the lights work just the annoying warnings.
Has anyone come across this problem?

Any error codes read with good Fiat diagnostics, MES, Snap On, MaxiEcu etc.?

I only B100A and B1009.
Both relating to side lights even though they are working fine. Could the bcm be from a different model. If van or truck. I have heard of the resistance values the bcm needs to see , especially when fitting led park lights.

Canbus error codes can be caused by wrong type LED bulbs I have read.
I see there is a Technical thread on Forum from years ago mentioning that " B1009 error /fault code ?" in April 2012.
Does your diagnostic tool give any more detail, the ones I mentioned may be more helpful.

Thanks for the reply I'll try and find that thread.
I'll contact fiat and see if they can tell if it has the original bcm fitted. There must be a way to find out.

It doesn't go into much detail though.
