Hi all,
I have a 2007 VDJ200 landcruiser and recently it won't start. I have narrowed the problem down to the brake pedal. I have checked all fuses (which i can find anyway, 1 fuse box in engine bay, one in LHS footwell) and they are fine.

If i connect 12v with a long peice of wire going from the battery to the brake pedal switch all is fine, brake switch works and i can start the car. That's how i know it's something in that circuit.

Does anyone have any ideas where i can go from here, does the BCM control the brake pedal?

Ryan,
Check with LCOOL. No start - brake light fuse

Try this-- from a search
Got in the car, and with foot on the brake, the usual green LED on the Start button was not there.

So with foot OFF the brake pedal, pressed the Start button once for Acc position and then held it down for about 12-13 seconds.

Hey presto, the mighty V8 roars into life.

Good Luck

That procedure will override the problem but not fix the fault.

Check all the light bulbs in the brake circuit are working.

The stop light circuit is quite complex, first off replace the fuse as they can have hair line fractures and the break might not be obvious.

Power from the fuse goes to a connector possibly in the fuse box, it then goes to the brake light switch and the stop light relay assembly. The power comes in to the switch on the blue wire which is the one I assume your applying power to, then via the switch when the pedal is pressed and out on the red wire to the stop light relay. There is other wiring involved but see how go the above.

thankyou - i was applying power to the red wire, but this is quite helpful, perhaps i can run power to the blue wire and fix it that way

If it is the actual brake switch, one of the wires will be from the fuse and the other to the brake light side. So which side, are you powering?

Check the fuse box and see if power is getting to the blue wire.

So hopefully you get it sorted out and running.

So now I have to ask does this mean if a fuse or relay on the brake system fails you can be left standard in a new vehicle ?

still havent sorted it out. STOP fuse keeps blowing .
to answer your question, yes, but if you hold down the start button for about 30 seconds, it sometimes over rides it, and you can drive without any accessories or lights.

Quite often the trailer plug wiring is the reason for stop light fuses blowing. Maybe disconnect it temporarily to see if the fuse stops blowing.

Don’t you just love how the manufacturers have complicated things. I can’t see why what should be simple lights wiring needs to be so involved with other stuff!

9 times out of 10 you will find wiring has been damaged on the trailer plug, If you have a brake controller in the vehicle, unplug it and try a new fuse, if it doesnt blow, you have a controller issue.

FWIW
My year 2004 100 series was non starting randomly. Traced to isolator part of the anti theft stuff. Bypassed to get car back working before replacement of isolator. Just a thought.9
