Focus 2006 2.0 Petrol Dashboard lights On and Car Won't Start


Recommended Posts

Hi All, Badly need your help and expertise,

Last night I tried using a modified elm327 to usb cable and forscan to scan DTCs on my Focus. After reading DTC's I disconnected on forscan and turn off car ignition, but dashboard lights won't turn off even the key is removed. I removed the battery overnight because I don't know what to do. Then tried to connect it today but still the dashboard lights are on even with no key. Please help me, car won't even crank. See forscan log below:

Here is what the dashboard looks like:

It looks like you disconnected before Forscan had finished communicating with the vehicle.

Disconnect the battery for ten minutes, press the brake pedal a couple of times whilst disconnected then re-connect and see if it solves it.

The first time you connect a vehicle to Forscan it reads all the modules then downloads loads of files related to the vehicle to make it quicker to connect the 2nd time. It will then ask you if you wish to save the profile, say yes, at this point you know Forscan is ready.

Then you can read and clear DTCs self test modules, re-set modules etc etc

Also, make sure your lead is communicating with the vehicle correctly, there are some how to's on adjusting settings for certain USB leads

Will try to this Good Sir. Regarding the Forscan, I didn't disconnected it until I noticed that the cluster lights are on even when the ignition is off - (Forscan asked to turn ignition off and then back on. I will update this thread once I tried your advice Sir. Again, thank you.

I did something simialr a few years back. I was using a crap elm cable. Ended up having the AA out to basicly reset all the codes adn get the car runing again. Is yours a decent one?

Hi @guy woodbridgeSir, I got it for a cheap price, so I think it's not that decent. Just an update, I tried doing Sir @DaveT70 advice, pressed the brake pedal a couple of times and connected the battery again, and the cluster lights are off, when I tried to start the car, the cluster freezes again, tried to turn ignition off and the cluster won't light off. Is it possible that I have a faulty ignition relay? fuse? or switch?

If forscan is working now and your lead is connecting properly:

Connect vehicle to forscan

Clear all DTCs, Try to start vehicle.

Reset PCM, BCM and IPC (maintenance) 

Self test PCM (Engine off) BCM and IPC. (maintenance) 

It does sound like the key has removed itself though. Have you got a spare key? Is the red immobiliser light on the cluster flashing?

Hi Good Sir @DaveT70 here is the result of forscan.

My cluster lights are not turning off, Tried to check the fuses related to instrument cluster visually, no disconnected fuses. I am getting depesperate to get my car fixed. 😞 thank you Sir.

It looks as though you have the common MK2 Focus instrument cluster fault, you have CAN communication issues and "Theft Detected" warnings.

The solder on the board of the cluster has gone down and will need to be re-soldered, look up on ebay there are companies you can send the cluster away to for repair.

Search on ebay for "Focus MK2 Instrument Cluster Repair" - Don't pay any more than £60

It'll be OK then, as soon as you reconnect repaired cluster the faults will go away, use Forscan to clear codes though

Ah, you're not UK.

Instrument cluster needs stripping down and the contacts re-soldered onto the main board.

Info can be found on google, DO NOT buy a new cluster, the re-soldering will fix the issue

No Sir, I am from Ph, struggling to find a ford specialist here in our town. I am trying to seek for advices that I will relay to the mechanic to check. Thank you Sir for replying. Will update you with anything that will come up.

Hi Sir @DaveT70the car started after removing and cleaning the instrument cluster. but my temp gauge spiked after 30mins of starting the engine. I am not sure If I calibrated the needle wrong or there is something wrong with my cooling system.
