View Full Version : The Big Day and the little switch

So there we were all dressed up and raring to go..........that was until I put my foot on the brake pedal and hit the start button! Bing - Bing - Bing, and up comes the dreaded yellow triangle on the dash along with a number of warnings about all sorts of items that were, to put it mildly, 'stuffed' or so it seemed.

This was Sunday morning last at 1100hrs. More importantly we were still in the drive of my property by the house. A quick check of things and plug in the IID tool and all the faults were confirmed. Woe is me!

Oh well the local LR service agent also happens to be the RAC folks in a town not too far away. Onto the RAC then. In due course out they come and after a little to do over finding my place (rural property) the rescue or so it seemed was to hand. We got the D4 to restore itself after about 15 minutes shut down. In consultation with the good RAC chap and with a view to heading to the service agent first thing in the morning we resigned ourselves to being a day or two late starting our journey.

All good from my perspective as I was not about to hit the road into a regional area with caravan in tow and vehicle that might not be behaving. I might add that the D4 has 297,000 plus kms on the clock at the moment and it has not let me down previously.

Given that I have owned and driven the D4 from brand new in 2011 I reckon that's not too bad.

So there I was sitting around at home thinking....mmmmmmm.....might this be a brake light switch fault, reckon so! Over to the shed and into the D4 rummage around for my spare switch that I have carried almost since the day I bought the vehicle. Found and installed the switch hit the go button but the faults persisted (No I did not clear them with my IID tool) whats more this time the vehicle dropped to the bump stops. Whats that word they use in the Toyota adds? Oh well back onto the RAC and get the vehicle towed in the morning.

Long story short, after the ignominy of being towed, it turned out I was onto the problem and the service agent had it fixed in no time flat......drove home hooked up the caravan and arrived at my destination one day late.

So the brake light switch had crapped itself and my replacement switch was used (yes I purchased another spare) and I was advised that after fitting same switch I should ensure push the brake pedal down and then hook my foot behind it and pull it back. After which I should then clear the faults and all should be good. OK I will remember that.

Mind you it was good to have my service agent spend a period of time checking that all was well with everything else. Peace of mind as I set sail.

That damned little (FoMoCo Part) switch caused a bit of a problem....but when you think about it how many times since 2011 has that switch been operated........all in all, probably it did a really good job and maybe it should be a service item.....oh I forgot your not supposed to keep the vehicle for that long are you?????

Wow that went very suddenly, when my needed replacing at 1st I thought it was something to do with the steering angle sensor or body roll as I noticed the alarms would come on when turning a corner or taking a bend, on a lane change even, after a while I worked out that I have a habit of touching the brakes before a corner, bend, lane change, to sort of steady the car, and it was actually the braking causing the faults.

I do vaguely remember doing the hard reset (battery lead shorting) at this time, not sure if it was before or after replacing the switch though.

No such luck with this one.....one minute all is good next kaput! Still, if your going to have a failure in the driveway at home is a good place to be!

Sounds like a great spare part to carry - do you have a part number handy at all? I might treat myself to one...

This this would be the correct part? I also have a MY12 2011 build D4 with 205k on the clock (with the only issue since purchase being a fuel level sender and a weaving driveline seal) and after seeing a few of these stories I think I’ll apply some preventative maintenance.

Same item but that is what i'd call a cheap knock off, pay the extra few bucks and get it from a ford dealer.

Yes go genuine. I went aftermarket and it went bad in no time.

Genuine, $36 delivered. Ordered one and fixed my issue. Having declared myself a mechanical genius, I ordered a 2nd as a travelling spare.

One giveaway for not being genuine is the grey or brown base instead of white. The switch with the grey or brown base sells for under $10 on AliExpress.

The LR genuine part from a local LR dealer was the cheapest of all when I bought a spare for my D4.

Thanks all, have purchased one and will swap out, keeping current one for a spare as I have had no issues yet it should be fine for spare purposes.

Disagree. Change it and have a partly used one in the glove box. At least you guarantee yourself a long time between failure.

I'm with Discojeffster......change it out and keep the old one. Even if you have an IID tool or equivalent to clear the faults these things always (for me at least) happen at the most awkward time....e.g. in the ****ing rain, after dark, on a muddy track when my Led torch has a flat battery and there is no signal on my phone etc. etc.[bawl][bigsad][tonguewink]:wallbash:

So 6 months down the track and you are out in the sticks and your newish switch fails, swap to the used one and it also fails as its already used = up **** creek.

Buy 2 of everything that may fail. Problem solvered but you may need a trailer behind as well.
I'm going to get one of these switches plus a new soldering iron for the transmission controller when it fails, plus 2 jacks, plus a load of tools, plus I have an Gap ID Tool....... "Where will it all end?" I ask myself. :(

Actually I checked the price of these switches with the stealer I bought the D4 from today. 65 bucks I was quoted. I said I'll check with a Ford dealer but he assured me that many people find they are dearer. But he would say that wouldn't he. :)
