Quickclear front screen

Recommended Posts

Having issues with my Edge Quickclear front screen.. Every time I need to use it it won’t work. Been back to Ford several times and had the battery replaced. Apparently if you battery is lower than 80% it won’t work. I have just picked my car up from Bristol Street after having the Fastclear screen check and was told it did not work as my battery was only at 51%. I am at a loss at why this is the charging system checks out and the car is used on a daily for at least 10 miles or even more. The only extra I have fitted is a front and rear accident camera that was professionally fitted by a local auto electrical company (Turners). The car starts easily and the heated rear screen works as do all the other manafactures  fitted auxiliary items. Can some one shine some light on this. My mate has an 2009 Monda fitted with the same camera and he has no issues with his screen.

First, I would find out where your 'professional' installers have tapped the power for the camera's from, then go from there. Rule out non-standard, recently added stuff, before thinking its something wrong with the car. The Left and right sides of the windscreen are fused and relay driven separately, so its something common to both, that leaves the GEM and whatever it needs in order to switch the heaters on, i.e. panel switch (although you can control it via Sync), supply voltage (influenced by battery state and alternator output). There is also the common ground to the windscreen elements.

I would get a multi-meter on the fuse outputs and check to see if that's ok, then check the GEM ECU for any DTC's. If there is an over-current or open circuit element, you may have a fault code logged.

There is also an option to Enable/Disable the front heated screen in the GEM, so that needs to be checked to ensure it hasn't been disabled (either accidentally or through corruption of the config)!

You also mention 'Bristol Street' ... I would go somewhere else as I've never had a single good experience from them and their service/technical department is useless. So maybe take it to an independent Ford dealer who cares about its customers and the cars they service!

Just had a conversation with my local vehicle electrical specialists and they believe the accident camera is not at fault as it draws so little current. It has less an impact than a very cold night. What was suggested it was my town driving with the auto stop start system causing the drain. It takes about 5 miles to restore the battery of the charge used for every stop start. I will be trying a few experiments. One being switching off the stop starting system and monitoring how the batteries charge holds out. This will have to be done on every journey as can permanently switch the system off. This will be monitored using a battery charge % gauge. The next will be by programming the parking monitor so it is switched off when the vehicle is parked. Will report on what results I get

Used to work for Bristol Street in Bromley many years ago also Dees in Croydon both had their problems. The car has now been to both with the same diagnostic that battery was below 80% thus front heated screen won’t work. No real explanation other than to point the finger at the accident camera as it none standard. As said in a previous post visited the people who fitted the camera they checked the power drain and was very low in the region were it should be, and pointed more at the stop start system when driving round town. As said going to do a couple of tests to try to get to the bottom what’s causing the drain

Your short drive cycles and especially this time of year when the lights are on does sort the good batteries from the bad!

However, I have worked on Auto Stop-Start systems for a number of automotive and off-road manufacturers, and I would say that the system is very complex and takes into account around 8 to 10 vehicle parameters (including engine mechanical service loads like A/C, HVAC state, engine oil temp, outside air temp, coolant temp, battery state, electrical load ... which in a lot of systems, is partially dumped during the stop start cycle), drive cycle duty times and frequency of those cycles. The system will not allow a stop (and hence a required subsequent start) to occur if any of those criteria is not met. I would not expect that to cause you issues with the battery unless there is a fault with one of the sensors that monitor battery state of charge. If that is indicating a better state than the battery really is, then that would be the only reason for what you are seeing or have been told.

Most ECU's on modern vehicles consume less than 1mA (usually in the uA range) when in sleep mode or if not essential to security or entry/exit, are powered off altogether by another ECU. Drain on your battery when the car is asleep is usually less than 10mA total. You have around 24 ECU's in an EDGE.

So does your camera have a sleep mode too? What does it draw when the car is asleep? What do they quantify as very low? If its only got a single power input I suspect it won't sleep as it doesn't know when to! ... unless it has a builtin motion sensor!

Hi  I have had exactly the same problem on a 2015 Galaxy Titanium X

Start stop and heated front screen stopped working around 12 months ago, and it has been back to the dealer on numerous occasions. Has had a new battery fitted but still doesn't work.

I have no camera fitted nor anything else to drain the battery,.

I charged the brand new battery for 6 hours, and after getting full charge on the battery charge machine drove the car for over 30 miles on a mixture of roads

When i stopped the car kept running, and showed the A symbol on the dashboard, but as ever, it was "greyed out" with a line running through it.

The message on the dash said "engine on due to vehicle charging" (see attached image)

Were you aware there is a message section on the dash for Auto Start/Stop?

Use the left arrow keys to go to Fuel mpg, then arrow up or down until you see the Auto Start /stop message

The Ford dealer has no idea what the problem is, a mechanic sat in the car with me for nearly an hour and connected his laptop and was totally confused by some of the readings he was getting

Personally i think this problem will never be fixed, so i am getting rid..

Best of luck!!

Yes when the auto electrician checked the draw current it was just below the spec of 295ma (293). This was measured with the engine off. Not sure what the drain was with the accident camera in it standby mode, but maybe a question I should ask. Waiting on a digital battery charge condition gauge so can keep an easy eye on on battery charge condition. Also going to set up a battery charge socket similar to what I use on my BMW K1300 and connect to a battery optimiser/charger. I will be using a DIN socket and plug with a waterproof cap same as fitted as standard on the bike. I will also have a look at what Davewill5 said as not awear I had this facility. I am also in the mind that this car will go next year in favour of a Jag, Lexus or Audi

Just had a look at the stop start on the info screen no facility to permanently switch off just that engine is running and is normal. Point less information, but like traction control no option to turn off

Going back to the accident camera it has a motion sensor and impact sensor both area adjustable. Have now programed parking mode off so no current drain whilst car parked. The camera is a dual set up QVIA AR790

As a manufacturer, they want you to use Start-Stop to reinforce their 'Green' credentials!! It is a pain, but my start routine is to press the start button, go to the centre console and turn stop start off, put it in drive and release the park brake ... Its like second nature to me now, but I really don't like it when it stops the engine so quickly after stopping.

As a side, I've noticed that if you put the car in reverse on a hill and release the brake, the car rolls back without being driven by the engine and it thinks the engine is not needed (forward speed is zero .. or less!)) 'cos the start-stop then stops the engine ... even though the car is still moving!! Bit of a software bug me thinks!!!
