Popular Post Phil21185 Posted June 12, 2017 Popular Post Share Posted June 12, 2017 Me: Got my modded ELM! Yay! Me 5 mins later: Killed my car. Boo. Me 2 mins and a lot of swearing later: Thank holy turdballs I took a save of the ECU configs! Explanation: Got my ELM as I always like to bugger around with things and see what's what. Fine. Really all I wanted to do was to enable auto door locking when you drive off (I live in Gainsborough. They'll have your wheels off if you're going less than 20mph... ) . Found the setting, changed it to enabled and all seemed good! Unplugged the reader and took 'er for a spin round the block. At 3mph my doors locked and i do this face ---> Shortly afterwards on the same trip I notice my cruise control/limiter controls don't respond. I do this face ---> cos I'm thinking I probably caught another setting without realising. So I pull up at my house and plug the reader back in but stupidly forget to switch the engine off. As FoCCCus grabs my cars settings, the engine cuts out and when FoCCCus loads, a crapload of DTC faults appear on EVERY system (BCM, IPC, etc. But most importantly PCM). I do this face ---> and clear them all with the software - they're all loss of signal faults so I assume its cos the engine cut out on its own but the PCM faults persist. I look down the list and see 'Crash'. I do this face ---> as I realise the car thinks its been involved in a crash as the engine was killed and will not allow it to be started again. Lo and behold it wont start again and I can't clear the fault. I'm now doing this face hoping the wife doesn't hear the car 3 ft from the lounge window not starting --->. Thankfully I also had ForScan which did clear the Crash fault and after restoring the settings from a backup I made at first read the car started fine again. I also re-applied the auto-lock setting and was careful not to touch any others. The Cruise still didn't work immediately, but after cycling the ignition completely the controls responded. Happy ending, but it was Brown Pants time for a few minutes... So the moral of the story: ALWAYS take a backup of your car's settings before you tinker and NEVER use an OBD reader while the engine is running! Just don't be thick like me =] 10 1 Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted June 13, 2017 Share Posted June 13, 2017 And the moral of the story is-ALWAYS save your original configuration files prior to altering anything.Sent from my SM-G930F using Tapatalk 3 Quote Link to comment Share on other sites More sharing options...
vibeone Posted June 13, 2017 Share Posted June 13, 2017 Never had the crash indicator fire, but I think despite the warnings, if you have an as-built, you'd have to have bad luck to completely brick your car. I accidentally turned on loads of stuff the car didn't have and all hell broke loose, but easily fixed. Also, even with VCM you get the mass of comms errors so that just seems to be the system. 1 Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted June 13, 2017 Share Posted June 13, 2017 After running Foccus to enable dash nav turn notifications I had to run Forscan to clear some DTC that were thrown up.Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
mike6688 Posted June 13, 2017 Share Posted June 13, 2017 Yep I've had this happen - so scary; engine management light came on and car wouldn't start at all. First time I'd ever used focccus or forscan and thought I'd completely wrecked the car. Was able to clear error codes with forscan and all was fine Quote Link to comment Share on other sites More sharing options...
alexp999 Posted June 13, 2017 Share Posted June 13, 2017 Just incase you hadn't taken a backup, you can also download the as-built data from here: http://ford.xtlt.ru/ab/ I did have a similar moment of panic turning on hill start assist and DDS for my mum's Focus. After programming the BCM the dash lit up like a christmas tree. I'd already got Forscan installed so scanned and cleared and they went away. 6 Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 13, 2017 Author Share Posted June 13, 2017 Yeah I realised that things weren't as drastic as they seemed but I was still sweating a bit til I got it figured out. FoCCCus and ForScan are big leaps from Formidable for my mk1.5! "Ooh look! When I press the accelerator, the revs on my laptop go up too! That's cool <nerdy laugh>" 3 Quote Link to comment Share on other sites More sharing options...
JamesMalin Posted June 18, 2017 Share Posted June 18, 2017 What's the difference between FoCCCus and ForScan then? I presume you download both to your laptop and use them via ELM connector in the OBD port? Newbie to this sort of thing :) 1 Quote Link to comment Share on other sites More sharing options...
alexp999 Posted June 18, 2017 Share Posted June 18, 2017 Focccus is primarily for editing the central config on the car. Forscan is primarily for code reading and resetting although it can do some programming too. 5 Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted June 19, 2017 Share Posted June 19, 2017 Forscan can edit hex codes, code keys and suchlike whereas Foccus changes asbuilt data for switching on non standard / premium features like nav, cruise control etc.Sent from my SM-G930F using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Phil21185 Posted June 19, 2017 Author Share Posted June 19, 2017 It'll be really nice when there's a full mapping of the settings. There's a lot of 'unknown' settings in FoCCCus and I don't have the bottle to fiddle with them Quote Link to comment Share on other sites More sharing options...

Just code a key via forscan and an elm? Might be nice if the obd slot was disabled while the alarm was activated or something... Quote Link to comment Share on other sites More sharing options...

More involved than that.They 'spoof' the car into thinking a key is present.There are dummy obd looms on eBay.Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...

I was thinking of doing the same sort of thing but with a custom connector. Then I'd just keep the obd port in the house until needed. In fact it'd be quite nice for some electronics genius to come up with a circuit attached to a dummy obd which would fry the equipment thieves use... 1 Quote Link to comment Share on other sites More sharing options...

Kevh17 Posted June 22, 2017 Share Posted June 22, 2017 I installed a sync 1.1 head unit and screen but since realised it won't work with a pre-sync car and luckily now found a pre-sync screen. bluetooth and USB functions still won't work, this was the problem with the sync head unit and screen, and Focccus shows the serial number for the sync screen. I've changed the system settings back to standard bluetooth and branded ICP from sync but it looks as though I need to download a file to change the serial number back. There's a number of these as part of Focccus software download but not one marching serial number am5t-18b955-cg. How do I get these?

Thanks I thought the serial number for the screen was stored in the ACM tab of focccus but it's in the FCDIM, obviously, and it shows the correct serial number now. I also mentioned the USB doesn't work now but it does, it's just the bluetooth which isn't working now but my phone says it's connected and it mutes the stereo when I get a call, as does pressing the 'phone' button.

FocusStMK3TDCi Posted July 2, 2017 Share Posted July 2, 2017 So just did this to my Focus, had the engine running and run Focccus, car stalled and every error possible started blinking on the dashboard. Totally thought i had bricked the car as nothing would work. To make it worse, i hadn't taken a backup (OMG i wish i had to begin with). Came online to see how to fix this as my laptop died (such bad timing) so couldn't get back out to check it. After 30 mins, laptop charged partially so went back out with ForScan to clear the errors. I didn't even get that far, when i got in the car there were no errors. Pressed the start/stop and the car came to life, no errors. Not sure what happened but could only assume leaving it for a bit went into sleep mode and woke up with its errors cleared. Cannot even describe how much i was sh*tting myself thinking i had broke my new car! Lesson: Always take a backup and start Foccus with the engine turned off! Thanks for everyones insight on this!

v530anh Posted July 3, 2017 Share Posted July 3, 2017 It is OK to use forscan on mk1 with engine running. I did it last Christmas. Quote Link to comment Share on other sites More sharing options...
