Yes, it's true.
But first some background....
During a trip across the Simpson, just after lone gum, my CEL came on. My car was brand new, and just 5 weeks old.
I stopped the engine and it wouldn't restart. Not the best spot to have this problem.
I disconnected the battery to reset computers, and it started. Phew.
Later that afternoon after pulling up to camp, I turned off the ignition and removed the key.....but the engine was still running. WTF! To stop it I pinched the fuel line to starve it of fuel.
The car still 'worked' and after a few days of learning the symptoms it turned out that if the headlights were in auto or ON, I could remove the key from the ignition and the engine would still run. To turn off the engine I just needed to turn off the headlights.
To cut a long diagnosis story short, the fault ended up being a failed diode in the wiring loom inside the ARB bull bar.
Who would have thought a fault in the lighting circuit like this could prevent the engine from stopping? I reckon the diode was part of the daytime running light in the bar...but not sure.
Anyone explain it how this could occur?
