( Right Door open) sign on dashboard, Alarm light blinking/ Car not locking

[joe1989]

Hi guys,

I tinted the windows on my granturismo yesterday evening. After the guy finished, the car stopped locking completely. I cant lock unlock the car using the buttons inside the car, nor the buttons on the remote key.
Also, the right door light on the dash board is on. The door is closed but still says opened and beeping while i drive. I am assuming its a drop of water from the tinting process that passed all the way down to the sensors. Its been 24 hrs already that this has happened. It should have dried. I removed the battery cable twice already for more than 15 minutes but still the same.
Any suggestions what the problem could be?!

Has the battery charge level dropped ? Assuming he had the doors open for a while during the instalation process.

Isolating the battery and putting on charge it on charge. A combination of a fully charged battery and it being isolated for more than 20 mins will hopefully clear the errors and allow you to lock the car as normal.

Thanks for the advice spkennuk. But why should the passenger door show that its opened?? I always have faced battery drainage in my car, but never had this thing happen! The airbag light turned on also today out of nowhere. Isnt there an electrical fault inside the car?

I suspect your solenoid for the door lock on one side of the car is either faulty or got water in it. However i wanted to rule out a low battery being the trigger factor.

Try locking the car with the key instead of the fob on both the driver and passenger side and listen for the solenoid activating.
The solenoid gets a pulse if you use the key or the fob but if you use the key the pulse is slightly longer. In effect it gets a little more grunt to move the mechanism.

If one side tries to activate and the other doesnt then you have narrowed it down. If that proves to be the case then you can try some wd40 on the key and operate the lock on that side 4 or 5 times and see if it springs to life. If it does it may well prove to be a temp fix. The solenoids are around the £25 mark if it is faulty.

The airbag light could be down to a low battery and i think you need an sd2/3 to clear the error but i am sure somebody with more knowledge than me on the GT will be able to assist on that one.

If you pm catmanv2 (chris) on the forum i think he has the wiring diagram if you need it.

Nope sorry
Been thinking about this, and your reaction is same as mine was, but thinking further the 'close' sensor is different from the lock solenoid. The body computer shouldn't care if it's locked or not.

The switch is in the lock unit though, so the solution may be just replace.

The door closes fine. Just the message on the dashboard + beeping is annoying. Doesn't lock unlock using the buttons inside the car. Locks using the key from outside. Using the remote key, it sends signal, lights red but stays opened. The second hard button on the door handle opens the car only. Both sides first button on door are disabled.
And this all started the moment I had to leave from the shop. Could a drop of water cause all this?

 

[spkennyuk]

Any water and electrics do not mix but italian electrics and water is a whole different thing. Its like throwing holy water on a demon

David howson or voicey could possibly assist further i suspect.

 

[CatmanV2]

Rather sounds like something is very upset

Can the locks be swapped over chris drivers side for passenger side ?

Just thinking out loud. If the door open warning changed sides then it proves the part at fault. You may also find it sat in a puddle of holy water

I doubt it. Different part numbers. I'm not sure how easy it is to get into the door either. There's not been a how to for the GT as yet.

The more I think about it though, the more I'm convinced it's the switch. Just a shame I can't have a look at mine.

Joe, I'm pretty sure that if you look at where the striker goes into the lock you'll be able to see the bar that actually keeps the door closed, but often there's a small lever that is the sensor switch. Can you see that? If so, if you move it with a point tool does the warning go off (even with the door open)?

Thats all i see inside the latch. I can't locate the sensor

 

[CatmanV2]

Indeed. Sorry I think it's going to need a dealer visit unless I get my car back in time to take a look before I travel.

It's a fairly routine diagnosis using an SD3 connected to the door ECU and the body computer - the SD3 allows you to monitor all the signals from the different sensors and switches so you can work out which is at fault.

My guess is that the tinter has had to trick a switch that the door is closed when it was in fact open so that he can access the full window (when the doors are open the glass drops an inch remember) for tinting purposes. A switch is now broken and actually showing door open.

The only other thing to do until you can get it hooked onto an SD3 is try electrical contact cleaner in all the switch areas. If you want to remove the door card then that is also an option.

The mechanic that fixes my car, has an access to the dealer's SD3. He only can borrow it next week. In the meantime, he asked me to slightly open the windows for humidity caused by the water to evaporate and remove the battery cable. Should i just wait until then? Will he able to turn off the fault using the SD3 or something must be replaced for sure? I need the car in the next couple of weeks, that is so not a good time for this S***!!
