Freelander 1 Self Test Mode - Freelander 1 diagnostics

WARNING: repeatedly switching the ignition on and off may stop you from being able to start the engine on your Freelander. I have done this on my 2001 v6 several times with error code P1666. Clearing the code doesn't allow you to start the engine. The way I get round this is to disconnect the negative terminal to the battery, then connect it again. I was then able to start my engine.

Not all Freelander 1's have the STM option available. It's possible to enable or disable it in the ecu but we don't know if it will start working if the option is changed from dissabled to enabled.

This fred will be updated with more information soon.

Self Test Mode

Freelander 1's have a Self Test Mode, which allows you to control the main computers outputs like the tailgate release, door locks, wipers etc. I used this recently to open my tailgate, as it wouldn't release because the tailgate window wouldn't drop. If more people knew how to use Self Test Mode, then they would be able to benefit from it. Some of this is cut from the rave disk. The rest is written up by me.

I've put this thread up for people to make comments on how to improve it, by checking the instruction for themselves.

My Freelander is a 2001 v6 auto, so I need some assistance from people with a manual gearbox Freelander. Some of the features I'd like tested while your Freelander is in Self Test Mode are:

1. Clutch pedal - when pressing it does the horn bleep and the internal lights flash? Not sure if there's a position switch on the clutch pedal.

2. Front fog lights - when switched on does the horn bleep and the internal lights flash?

3. Manual gearbox HDC switch on the gearlever - when pressing it does the horn bleep and the internal lights flash? It doesn't on my auto.

4. 3 door removable roof - does the horn bleep and the internal lights flash when the roof is removed and refitted?

5. The controls for switching on the diesel burning heater. Are there any, and if using them do they make the horn bleep and the internal lights flash?

6. Cruise control on the steering wheel? Nothing happens on my Freelander when the buttons are pressed.

7. Faulty door key - will a faulty door key still put your Freelander into test mode?

8. Test sunroof - can someone do this and advise if horn bleep and the internal lights flash? The fuse is removed on mine as it doesn't close properly so I can't tell.

9. Would be good to list if others living in different countries other than the UK could advise if their Freelander has self test mode. Can you advise the country your Freelander is from, and if self test modes works. Eg Germany yes it works.

Great, just the sort of good info that is required for FL owners.

when yu sorted it, Hippo can we have a full copy in the FAQ section please?

Good stuff!

Yes will do.

Thanks for the info Hippo I'm sure this will come in useful in the future

I've got an 04 td4 auto so can help with a couple of questions.

I will check point 2 (front fogs) and point 8 (sunroof) when I do the self test but can help straight away with point 5, the fuel burning heater is controlled by a temp sensor and there ais no manual switch for it so can't be tested.

I'll post up my findings once I've done the test.

Thanks mate.

A great write up Hippo .
Mine's a manual so I'll try and add where I can when I go through it .

Info I have so far:

Self test mode.

The CCU can be put into Self Test Mode to enable the inputs and outputs from the CCU to be tested for correct functionality without the need for TestBook (T4). To put the CCU into self test mode the ignition should be off with the vehicle unlocked and unarmed and the following sequence must be followed:

1. Insert the key and turn the ignition 'on'
2. Press and hold the rear fog switch 'on'
3. Turn the ignition 'off'
4. Turn the ignition 'on'
5. Release rear fog switch within four seconds of ignition 'on'

Note: When turning mine on, I turned the key to the second click, when the electric powers up. Also it took about 1.5 seconds for me to complete steps 1 to 5. Sometimes it doesn’t go into Self Test Mode first time. Not sure why. Think it’s due to getting the correct speed of the above entry steps.

On successful entry into the Self Test Mode the sounder will sound for 0.8 seconds and the courtesy lamps will illuminate for 0.8 seconds. I think from memory the dash board alarm light will illuminate for a short period. Other dash board lamps which illuminate are = abs, engine, oil, battery and the mileage display is as normal.

When testing an input, for example a door open switch, on successful receipt of the input the CCU will sound the sounder for 0.8 seconds and illuminate the courtesy lamps for 0.8 seconds.

To exit the Self Test Mode on a Freelander 1, just switch off the ignition and it exits the test. Doesn't matter how far through the test you are, or if you've gone round the test several times. Car will then operate as normal.

Outputs are tested in sequence using the CDL Central Door Locking “lock” option switch to progress through the outputs. A CDL unlock request repeats the last test. Outputs are either operated continuously until the CDL lock switch is released, or operated in a pulsed fashion until the next operation of the CDL lock switch. Output formats are described in the list below:

Output / Test type

Rear fog lamps - Continuous – interior light and sounder on for 0.8 seconds – fog lights on

Door Lock - Pulsed – interior light and sounder on for 0.8 seconds - all doors lock – can be opened with internal handle

Door Superlock - Pulsed – interior light and sounder on for 0.8 seconds - all doors lock – can’t be opened with internal handle as this is the dead lock option

Door Unlock - Pulsed – interior light and sounder on for 0.8 seconds - all doors unlock

Front wiper - Continuous - interior light and sounder on for 0.8 seconds every time the wiper goes to the rest position

Alarm LED - Continuous - interior light and sounder on for 0.8 seconds – alarm LED on the dash lights up continuously

Volumetrics - Continuous - interior light and sounder on for 0.8 seconds – I assume this is an internal self test. Not sure if there’s any way to test the volume sensing. I couldn’t get mine to do anything.

Horn - Pulsed - interior light and sounder on for 0.8 seconds – horn sounds

BBUS (battery backed up sounder) - Pulsed - interior light and sounder on for 0.8 seconds – I think another noise should be made here but not sure.

Heated rear window - Pulsed - interior light and sounder on for 0.8 seconds – rear window heater button illuminates – rear window may heat up, but I didn’t check for this

Tail window down - Pulsed - interior light and sounder on for 0.8 seconds – rear window drops fully

Tail door actuator - Pulsed - interior light and sounder on for 0.8 seconds – rear door unlocks – may need to repeat a second time by using the CDL open option to repeat this, to get the door to open so you can pull it open. The tailgate door handle won’t activate the tailgate release during Self Test Mode.

Tail window up - Pulsed - interior light and sounder on for 0.8 seconds – rear window rises fully – only happens if the tailgate door is closed

Rear wiper - Continuous - interior light and sounder on for 0.8 seconds – only if tailgate door is closed

Hazard lights - Continuous - interior light and sounder on for 0.8 seconds – both green indicator arrows illuminate on the dash board

Door open warning lamp - Continuous - interior light and sounder on for 0.8 seconds – red door open lamp illuminates on the dashboard

Seatbelt warning lamp - Continuous interior light and sounder on for 0.8 seconds – red seatbelt warning lamp illuminates on the dashboard

Handbrake warning lamp – Continuous - interior light and sounder on for 0.8 seconds – red handbrake lamp illuminates on the dashboard


If you continue to press the CDL lock switch, the tests will now repeat from the top of the list. You can do this as many times as you like.

Thanks Hippo, Is it possible for you to provide a video of you doing the Self Test, as I am unsure on the exact sequence of the steps you mention in your write up.
I am sure it must have taken you a few times to get it right when you did it originally.

Will do. It takes a few attemps to get it into self test mode.

Edit: Now I've worked out how to do it first time, every time.
