Check th wires coming from the pass lock (3) especially the wires going down the column where the tilt flexes them.

would that alow me not to scan the body control module with my scaner an could you send that wiring diagram to my e mail adress
[email protected]
You cant give me an E-mail address on here. No it shouldn't prevent communication to BCM. That diagram can be saved by right clicking and saving to clipboard. What scanner are you using?

How do you know that the BCM is not communicating? If it has a code for the anti-theft has set,then the BCM (which is in control of passlock) is talking. The U1000 code can set from electrical noise interference on the data lines going all around the car, this code should be disregarded unless it is the only code and it keeps reseting. I assume your car wont start now having the passlock code set.

when i try to use the scaner to check the door locks any other thins it says no comunication it keeps reseting the car will start an die within seconds
The car starts and dies because of the passlock code the wires to the column must be checked for that. You don't need a scanner to check the door locks. The problem with that is, because you checked all fuses, either a switch, a broken wire in the door jamb (most likely driver side) flex joint or, if its one door thats inoperative, a lock actuator. What other systems are not working?
Customer: replied 5 years ago.
the rear hatch lock the shift lock for the shifter another thing the security light in the instrument console doesnt light up at all

Have you checked all the power and ground to the BCM also check all the rear hatch and shift lock circuits using these diagrams. If all there, replace BCM and reprogram VIN.
