I cannot locate the DATA Problem

Hi,

The only serial data line related to the DDM is from the body control module. I attached the wiring schematic below that shows how they are joined. I highlighted the wiring.

What I noticed is there is a splice under the right rear seat that may have been damaged or disconnected. This is where I would suggest checking. If the connection is good, disconnect the battery and check for continuity in the wiring.

Here is a link you may find helpful:

Let me know what you find or if you have other questions.

Take care,

See pics below. Note: It was one page long. I had to cut it in half to make it readable, but I did overlap the two so you can follow from one to the next.

I'm still trying i have problems to identify the correct green data wire in the body control module plug. There are a few green wires. I have two plugs in the body control module and your diagram. regards

The one you are looking for should be solid light green. I is pin B-1 in connector 1. The connector will be gray in color.

Take a look at the pics below and let me know if it helps.

Take care,

Joe
