Re: EF Futura SW, possible Central locking problem.
Update and cause of problem found.
The switch mounted against the lock on tailgate is the culprit.
I havent had a chance to remove and test but I thinks its stuck so that it is 'closed' and as such, when tailgate shut, its not opening the circuit for the computer.
This also causes the interior lights to stay on as well as the light on the steering wheel above the ignition key.
The locks close but the horn gives a short toot as it detects an 'Open Door'
Temporary fix is to simply unplug switch connection inside the tailgate, this means the interior light wont come on when tailgate open but at least the central lock is working correctly.
If your interested, the cost of the replacement switch is $110.
That is not a typo, [U]$110 ,the damn thing is as big as your thumb in size and about 4 mm thick with 2 wires and a polarised plug at the end.
