New to this forum, hope someone can help.

"SOS call system failure" came up on instrument panel. Thought it was the battery in the Telematic Unit as suggested. Replaced this with great struggle getting into the rear roof lining! Checked the Fault Codes and removed them. When ignition turned on again I get the above codes. These refer to GPS aerial: open circuit, Telematics Aerial 2 Open Circuit, and telematics Aerial 1 Open Circuit. Can not find a schematic diagram for the Telematic unit to see where to start. Is it possible that I have not replaced the unit correctly or that a connection has come out? What connections are the aerials?

Welcome to the Forum

From  memory there are several connections but they should be colour coded I think the only route is to go back over what you did just to make sure tey are all correct an seated make sure the earth hasn't been disturbed

Good Luck

Thanks Dave.

It looks like that's the only way to go. I think it may be the 4 terminals that actually connect to the sharks fin. Maybe I didn't  push it right in when putting it back. Mind you the clip did pop out>

Hi Dave.

I have had another look at the TCU and re-fitted it.

After clearing the codes and restarting the ignition I get the following fault code:B7F317 "GPS aerial Short Circuit to ground" 

I know that in previous post you mentioned the earth connection, do you know where it is? Could it be one of the four terminals that go from TCU to the Shark Fin? If so any idea which one!

It seems to be that you cure one problem and endure another!!

Cheers,

Ray.
