Thanks for all the help Dave. I have finally sorted it!
I removed the Telematic Unit and took a closer look.
The 4 terminals that connect to the fin were twisted and not aligned correctly.
I fiddled around a bit and managed to sort these out. Next I checked the battery.
The terminals were not actually touching the contacts when the lid was closed. This was mainly due to the fact that the clip on the lid had broken off and the lid was not closing fully to push the battery
onto the contacts. So I bent the contacts out slightly, and stuck a piece of card on top of the battery
and closed the lid and taped shut with some masking tape! Replaced the unit, connected the three
cable connectors, and closed the tailgate. Waited a while and switched on the ignition and all the
codes had cleared on there own!! No need to clear any faults. After checking all faults, nothing found!!
After thinking that it could cost me a new Unit and Fin costing megga bucks, it cost nothing more
than a new battery (£25) and a bit of elbow grease.
Boy am I pleased!!
