[s-cars] Help for central locking and alarm

[Vincent Frégeac]

Hi all,

 

I’m asking for your wisdom once more. I decided to track all gremlins from
the winter and I do confirm, frozen water (snow, ice, whatever) works also
very well for multiplying gremlins.

 

So today is central locking and alarm.

 

What works:

-          The driver door manual switch closes and opens all doors and
trunk

-          The turn signals blink once for close and twice for open when I
use the remote

And that’s it.

 

What should work but doesn’t:

-          The only purpose of the remote is now to make the turn signals
blink. It’s very nice by night but


-          When I close the driver or passenger door with the key, it closes
the door
 but only this one.

-          When I turn the key twice to open the driver or passenger door

it opens the driver or passenger door.

-          When I close all doors with the central locking switch then the
driver door with the key, the alarm doesn’t switch on.

 

What I’ve done

-          Replace the RF remote receiver (no change)

-          Check the fuse

-          Check the signal coming from all switches (doors, trunk and hood)

-          Check the signal coming from the RF remote receiver

-          Replace the central locking pump/alarm/blablablabla central unit
(no change)

The only thing I’ve not checked yet (it’s raining now so I prefer writing
emails than working in the parking lot) is the door lock switches but both
the passenger and driver doors do not activate the central locking and
alarm, and I don’t see how both switches could have failed at the same time.
I’ve also noticed that, if I connect the central locking unit (all three
plugs) then I connect the battery, the vacuum pump does not work anymore. It
happens on both units. I have to connect another battery on the car, connect
the purple plug, then the other plugs, install everything with the foam,
install the car’s battery then disconnect the other battery. This means that
disconnecting the battery for another job will deactivate the vacuum pump.
This was not the case when I replaced the battery six month ago.

 

Last point, all this started when I washed the car with pressurized water
two or three month ago.

 

Any hints or BTDT? Is there a learning process for this central
locking/alarm unit like the door one-touch-up or the RF receiver?
