The Ford Mondeo mk5 (from 2015 onwards) has a number of useful features that are disabled in the factory but can be unlocked using free software and a USB cable, without any special knowledge. Here’s how.
You will need a compatible ELM327 cable. There are loads on eBay but it can’t be just any – it has to be one with a manual switch between HS and MS mode. The ones that lack this switch may not be fully compatible. Mine specifically said Designed for Forscan and cost about £15.
The switch wasn’t labelled so initially I had to guess which way was which. On mine, the HS position was towards the label side, so I labelled it with a sticker.
Now you need to download FORScan. There are versions for phones/tablets but to change settings you must download the Windows version. You’ll need the Extended License to change settings but fortunately there is a 2-week free trial. You can install FORScan but don’t activate the trial until you’re ready to use it!
First you need to start the engine and disable the auto stop-start.
Then you need to connect the cable up. The OBD port is under the steering column and has a cap on it.
Load FORScan, click the Connect button at the bottom of the window, and follow the instructions.
If it connects successfully, it will scroll through a list of modules that it has detected. Wait until it finishes, and then click the Configuration & Programming button in the left menu – it’s the one with the chip icon.
In the list of modules, scroll down and select IPC Module configuration. This is the module that controls the instrument cluster. Make sure you choose the one without AS BUILT format. Then click the Play button at the bottom. Flip the HS/MS switch when it tells you to.
Now you’ve got a long list of settings that can be changed. Most of them will require compatible hardware to be installed on the car so don’t be tempted to fiddle unless you know you have that hardware, and be sure you understand every setting that you change. Be sure to make note of anything that you change, so you can put it back if necessary. These are the settings that I changed:
- Auto Lock
- Auto Relock
- Autolocking While The Vehicle Is Moving
- Digital Speedometer Configuration
- Fuel Economy Menu
- Fuel History Menu
- TPMS Menu (Additional change required in BCM)
- Tire Pressure Gauge
In every case, I double-clicked the setting, changed Disabled to Enabled and clicked the tick. Bear in mind this doesn’t actually change it on the car – it just prepares a batch of settings to apply in FORScan.
When you’ve changed everything that you want, click Write, review the changes, and FORScan will change the settings on the car. You can apply them one by one if you prefer. The instrument cluster will go dark for a few seconds before reloading. FORScan will tell you to turn the ignition off and on again. On my car, every time it reloaded, the temperature reverted to Fahrenheit so I had to set it back to Celcius.
To complete the tyre pressure settings, click the Stop button to leave the IPC module settings. Now find BCMii Module configuration in the list and click Play on that. Look for TPMS (additional change required in IPC) in the list and set it to Enabled. Click Write. Turn the engine off and on again.
Some of the new features are a bit hidden. You have to enable the digital speedo by clicking the button at the end of the left stalk (which usually controls the lane keeping assist). The fuel history, tyre pressure and lock settings are in the left menu system. Changing the lock settings with FORScan doesn’t actually enable the lock settings, it just adds new items to the in-car menu so you can enable them yourself.

Great information thank you

Thanks your article gave me the confidence to go out and play. I managed to get the tyre pressure gauge set ok but the digital speedo was already enabled and I could not fully understand the comment on the lane assist button. Do you still have lane assist enabled or does it toggle through. Mine only controls the lane assist. More detail would be appreciated. I don’t suppose you know to set the traffic sign over speed chime do you ?

It’s probably an incompatible cable. I know some of them don’t work properly. I made sure I got one with a physical switch on the side.

Thanks for your reply,
I got the same cable/adapter with physical switch on side, exactly like your picture shows, bcoz i ordered adapter after I read your all instructions..!
Adapter works well With that FORScan software While unlocking something from the list like you said, everything works up to ignition switch off and on, but nothing changes happened on car…!
Cluster shows “BLIS MALFUNCTION”
Keep coming up again and again.,
What’s your advice please in this situation,
Still adapter issue you guess…..,
Thank you for your time

I think BLIS is the blind spot warning system. My car doesn’t have that but maybe yours does? I just typed it into Google and it seems like quite a common problem

So any idea how to get rid of this BLIS MALFUNCTION warning..?
please.

You have done something in the BCM for it to show a BLIS error (BLindspot Information System). BLIS is linked to several different systems – parking sensors, Park Assist, Trailer Assist and ABS sensors.
What did you change in the BCM, do you have BLIS from factory?
It has nothing to do with the adapter, if the adapter was incompatible then all that would happen is that you would not be able to switch between the HS and MS BUS. You would only see the modules on one of the two ‘channels’.

What’s the difference between Auto Lock and Autolocking While The Vehicle Is Moving?
LikeLike
I’m not 100% sure but I think Auto Lock means locking itself after a certain time when you get out of the car

Auto lock is when the car relocks after 20seconds or so after it is unlocked but no door is opened. Autolock when driving is exactly as it sounds, however it needs to be enabled in Forscan.
