2010 Defender 110 Puma 2.4 XS CSW Santorini Black

immobiliser stopped working, no start

So I'm thinking I have a short somewhere, I parked my car locked it and walked away. 30 minutes later I went to unlock it and nothing. I also noticed at the same time all of my interior lights are on but super dim, like 10% of normal, if I actually turn the light on it'll come on at 100% percent. Battery is fully charged, I checked all fuses and battery terminals are tight so that's not it. When I go to start it the alarm just goes off and the horn won't stop. I am about 3000 miles away from anyone who knows anything about a puma..... Any help greatly appreciated. 2010 def 110.

Update: Small Indy shop found a fault with driver door immobiliser, got a new one and now the front two doors open and now the car will start but the rear doors and tailgate door stopped opening and closing, again leading me to think I habe a faulty switch somewhere or a mystery short!

Super dim carlights? Seems like a battery issue to me. How old? What about undervoltage?

Tjhappel, your description is somewhat confusing.

What do you mean by the driver door immobiliser? Do you mean the door lock actuator (a solenoid)?

Would seem apparent that on the way to the rear of the car the power to the door lock actuators gets interupted. The fact that the immobiliser was setting off the alarm suggests that it senses that something had shorted. Did your indy disconnect a wire or bypass something to get things working.

My guess is the problem is in the wiring (damaged insulation, something shorting to the body) and not with the solenoid.

Ask your indy what he did.
Hope this helps. 1998 Tdi 90 SW,

sorry for anything confusing, the power door locks stopped working and the car wouldn't turn on. Interior lights were on and very dim even though the car was closed and locked. After a

ton of searching the right rear door had some wiring crumbling and overlapimg the other wires and short out the rest of the car. I have backup cameras installed and I'm not positive but I believe it's in those wires somewhere, my car is up and running now but lost the reverse camera and the rear speakers.

Thanks for getting back to me everyone, sorry for anything confusing. I really am thankful we have a site like this to turn to for help!

I had a non starting problem, similar to you. The AS10 terminals were corroded. These were cleaned and all was well. Might not be your problem but you never know!

Found the issue in right rear door, wires corroded and that was causing the short. Thanks for your help guys..,
