Remote Central Locking and Flashing Blinkers

[mal58 Junior Member Find all posts View Profile Close mal58]

Hi,
I have a 1998 90 series GXL with factory remote central locking. I've had the car from new.

It recently has developed a problem when I lock the car via the remote central locking that it flashes the Blinkers 16 times as though there is a door that is not closed properly.

I have checked and there are no doors ajar and no interior lights on, so am looking for some clues of what might be causing the problem ?

Cheers,
Mal

Hi,
As an update, I decided that I might have glitched the Central Locking Module when I recently disconnected the battery, so I thought I would disconnect the Module from the car and see if that fixed the problem.

On removing the side trim I discovered that the area under the carpet was wet. So I removed the Central Locking Module and found. Upon opening the unit, I found it had been wet and the electronics was growing whiskers and rust on the bottom half of the board. It was a wonder it was working at all.

Now having a background in electronics, I decided to see if the module was repairable. I have cleaned the module as best I can, but sadly at least 1/4 of the resistors on the bottom edge of the board are open circuit, and several of the capacitors are also damaged and are falling to bits. Sadly I don't think it is repairable.

I have rung Toyota, and they have it as a spare part for only $64 ish dollars, so have ordered a replacement. Hopefully it will arrive next week.

The next job is to find where the water came in and to fix the problem.

Cheers,
Mal
