Hi all. The other day I came home from work to find the hazard lights flashing for no reason. Upon starting the engine they stopped and when I shut it down they came on again. Any thoughts as to why this would happen. Ive taken the battery leads off hoping something would reset but no luck.

Check your fuse for the hazard lights, and see what else is using that circuit then check out that part of the electrics for something staying on.

In the meantime pull the hazard light fuse for when not in use.

Question have you recently installed or played with something electrical on the vehicle.

Havent played with or installed anything since fitting trailer brakes 3 years ago. Checked fuses to find the indicators run off the same fuse. I have pulled the fuse out while parked, now its a pain everytime I go somewhere as you could imagine. Might be a job for auto electrician.

The first thing he might do is check the hazard light switch to see if it's burned out.

Maybe you could check that for a start.

I assume like most vehicles these days the circuit also includes the alarm and door opening circuitry ??
Could be something in that little mess too ??

Hi,
There was a recall May 2008 for 100 series regarding a wire harness. (cut and pasted below). Its a long shot but maybe the harness insulation has worn through and is shorting against metal somewhere? but not enough to blow a fuse yet?

"On certain Land Cruiser 100 and Lexus LX470 vehicles, there is a possibility that the dash board wire harness may be abnormally twisted changing its intended routing in the vehicle allowing contact with the unprotected edge of the pedal support bracket. If the vehicle is continuously driven on corrugated roads in this condition, the wire harness will rub against the pedal support bracket damaging the wire insulation cover resulting in a short circuit and blown fuse. "

In plain language its a loom above the brake pedal support tower and needs a bit of flexii tube over it.Toyota will do it free when they do your front rotor bolts if you havent had them done either.

You dont happen to have a Tekonsha VOYAGER brake controller do you If so get rid of it or take it back and get a free upgrade.

The older ones would bring on lights at random and could flatten batteries.

If you have one try to get it replaced

They have been doing them free. They probably know the serial numbers that were faulty

What was the result? Did you have to get something changed. Have taken to a sparkie. Pulled something out (dont know what because wife took it in and cant remember what they did) and put back in and hazards stopped, but said this would not fix problem. 4 hours later they where flashing again. Sparkie says there is a controll box under dash that may need replacing. Need to take dash out to get too it. Any way we will see what happens.
