Hi.
My Xentry system will not recognize my car anymore. It will only see a 211.076 and not a 211.276. I can get in but of course I am limited to certain things because the computer will not see it as a 211.276. Also the Vehicle ID will not show on the screen. Some how I was able to put the vin in at some point a few days back but that screen does not pop up anymore. So basically my system will not read the car it self. If I do a check on the PCM it will show alot of options as not being there. What did I mess up with? Thanks

 

check the central gateway module on your car

 

OK will do. Anything in particular I should be seeing? Thanks

 

Ok from what I can see the multiplexer is not being seen. The computer will respond the same way even if I do not connect to the DLC connector. Something must be off but I can not find it. And yes the multiplexer does light up.
If anyone does repairs on these or updates for problems please let me know. I am pretty sure its in the computer but who knows at this point. Thanks
