Hi, anyone got any experience with Ford SMax lighting issues?
It's a 2006 Titanium. One of the front DRLs (inset in the round fog lights in the bumper) only comes on when the brakes are presses - it seems to be shorting onto the brake light circuit. The other side doesnt do this and functions normally.
Now front brake lights seem like a fantastic idea but it clearly shouldn't be doing this!
Does anyone know of any common faults in the light circuits or failure points in the wiring loom likely to cause such an issue.
The wipers on my wife's 2010 Focus stopped working last week. Hoped it would be a simple fix but garage traced the fault to water ingress and corrosion in the ECU BSI (?????). Side lights were also not working. Long story short, £780 to replace so I hope your problem is straightforward.
Not car specific - but if you've changed any other bulbs recently check them.
I had a weird issue where occasionally my cars engine would keep running after turning off the ignition - even with the keys out. Realised after a while that it happened if the lights were on and I have my foot on the brake. If I had the lights on the engine would continue to run until I took my foot off the brake or turned off the lights
A stop/tail bulb had been fitted the wrong way round (so the brake filament came on with the lights or the tail filament came on with the brake pedal)
Turned the bulb around and order was restored - just having those two circuits drawing slightly different currents created that strange behaviour with the ignition

Weird doesn't come close. How is that possible, aren't the locating pins staggered? Also what have either the tail or stop lights got to do with the engine running on?
edit Saw your additional para, still mystifying though.

yes - but the bulb could still go in the wrong way and work

I doubt it was an outcome they had intended.:-) Just a result of all the functions running through the same little computer. Its what can lead to folk going on expensive wild goose chases diagnosing faults based on the code the ECU gives you - tales with the same model of people spending £thousands on new fuel pumps and EDUs based on error codes only to find out the fault code was really caused by a blown bulb in the instrument cluster.
