Hi, My 2003 Alphard has suddenly started fashing a red light when it is swtiched off but not when you switch the engine on. It is a car sideways on and to the left of the battery light but flashes of so quickly I can not see more than the outline of a car. Does anyone know what this is please? Thank you

Hello Carole are you able to upload a photo 

Hi Lee, thank you so much for your reply but we have now been told the answer. Apparently it is a light to tell you the security is working. It hasn't come on before but the garage replaced a dead fuse so now it does. OK panic over.

Yes it's the car immobiliser should carry on flashing till you put the key in the ignition 

Would this potentially drain a battery at all?

Not really. It is an original feature of the car; so that aspect would have been considered by the designers.

 

However, it is the immobiliser; so you can't immobilise (sorry couldn't resist) it; and shouldn't want to!).

 

The symbol, I believe, is the silhouette of a car in black, with a white key inside.

That's the symbol indeed. Thank you!
