Land Rover Discovery 3 DEACTIVATE BUILD MODE & RE-ENABLE EAS - GAP iiDTool
HTML-код
- Опубликовано: 27 авг 2024
- In this video I show you how you can deactivate build mode (Transport mode) and how you Re-enable EAS using a GAP iidtool BT. This is what you need to do after replacing the air reservoir or have run any of the deflate procedures.
Disclaimer: I'm not a trained mechanic. The air suspension can be dangerous to work on if done wrong due to highly compressed air.
FAULT CODE: C1A00-53 (AF) Control module - System programming failure - deactivated
FAULT CODE: C1A00-53 (AF) Control module - System programming failure - missing calibration
Initial fault code for the reservoir replacement.
FAULT CODE: C1A20-64 (AF) Pressure increases too slow when filling reservoir - Algorithm based failure - signal plausibility failure

Great video and very helpful to anyone servicing their EAS as I have been for the past 4 weeks finding a compressor issue and leak issue (slow to fill). Gallery pressure includes the compressor, the centre block and all the lines to the front and rear blocks. It is a tiny tiny air volume. Once the tank pressure is restored the tank is isolated and the compressor vents (farts) the gallery back to a lower pressure as the tank is isolated from the gallery as a store of energy. The compressor can't start against a high head pressure which is why it vents. By monitoring the gallery pressure on the IID Tool you can also see if there is a bad leak in the gallery which will mostly be in the area of the compressor lid and connections if the pressure rapidly falls. Some say this gallery pressure will always very slowly leak and can never be perfect (I'm not 100% sure) the idea is to stop ambient moist air getting in and accelerating the demise of the dessicant. But since each time you start the car the compressor will always run and test and in very quick time replace the tiny amount of air to charge the gallery to 200-400kpa to know that the compressor is ready.
If the car sinks overnight it is generally a leak at the air springs (mostly) or front and rear blocks which you can remove the levelling fuse to isolate which corner has the problem.
The system is pretty cool and simple to understand once you study it and servicing the 3 solenoid air blocks is a great idea and quite easy.
Wow Richard, this is such a great comment and addition to the video. You know your way around the air suspension system for sure! 👌😊
The system is really cool and, as you say, once you get to know the ins and outs of it, it’s actually nice to work on too. 😊
Great details of information added by you and why I love this LRD RUclips community, if everyone share we all win. 👍😊
Thank you and keep it up! I need to do a round of checks as my front right is dropping over a few days. 😅
Best, Simon
@@LandRoverDrive 👍 understanding how quickly a good compressor gets to 1780kpa and at what temperature is a fantastic measure of compressor health. Temps up to 110-120C are normal.
The computer is very quick to disable the EAS and show an error once the fill speed reduces.
I have the following live values saved to quickly watch the compressor operations;
Relay position
Gallery pressure
Cylinder temp
Engine temp
Thanks for this video! You saved me. I put into build mode and I couldn’t figure out what happened. Thank you!
Glad the video could help! Bad design I guess. 🙂 Sometimes, if you have put it into build mode and turned of the car, on startup and when disabling the build mode you may have to run the rutine twiced to get it to turn it of. Not sure why.
For an overland overland preparation, which one do you prefer? Discovery 3 or Defender
Hey, I think they are both great and they both have their own charm. I’m glad I have had the opportunity to go overlanding in both. If I had to choose one of them today I would go for the Discovery for a bunch of reasons. I will make a video on that later but my main reason would be safety and traveling with kids. 👍😁
@@LandRoverDrive thanks my friend!
Hi could you please advise me where I can get one of these readers also the cost great video
Hey, you can just google iidtool and Gap-diagnostic. They have different online stores that sell them. :) I ordered mine from the UK as no one sells them here in Norway.
Did you engage build mode to do something first or was it in build mode due to the faults?
Was in build mode as I had worked on the car. I think it was when I change out the air suspension reservoir. 🙂 Videos on the channel in the D3 garage playlist.
I have a 2006 rrs supercharged... My car was fine and out of boredom i selected calibrate anti roll option then i got e 7 error code and my red suspension light is on... Everything still works ie suspension goes up an down etc but now the red light stays on and fault code C 1 A00-54 - Control module - System programming failure - missing calibration (AB)... 😮... Any advice please 🙏
Any advice, don't fix what isn't broken? 😅 I haven't been so lucky to have encounter the Anti roll bar system on the RRS. I would google the fault code. I would guess the air suspension also need recalibrating along side the roll bar, or maybe the steering column. Maybe there also is a sequense to it, one system before the other need to be calibrated. But I would look into the air suspension first.
@@LandRoverDrive cheers bud.. Appreciate it... Thanks for getting back... Everything seems to still work so I guess just ignore the lught.. Lol
Hello, I don't understand what is normal working temperature of air compressor and what is a maximum temperature, that is allowed?
Thanks
Hey, I'm not 100% sure on the cut off temperature but I have read people get readouts around 130-140*C so it's up there. Normale operating temperature would change a lot depening on the outside temperture. I think it runs pretty hot and if the system got a leak some where I would expect seeing the 100*C mark when it's working on filling up everything. Hope it helps. Best, Simon
Simon, is that OBDII reader of any use on your TD5?
Hei Quintin, sadly not. That would have been great. I don't have a reader for the TD5, but that has not been an issues yet. :)

Hi could you please tell me where I can get this reader please and cost
Hey, just search for GAP iiDTOOl and you will find some online stores that sell them in the UK at least. 👍🙂
Hey man I just deflated my suspension for a service using idtool and then I wanted to check my gallery pressure live value like you did. I dont know why but it stays at 1.9bar not higher. I was able to drive the car normally and use the suspension lower or higher no problem but my idtool display 1.9bar as gallery pressure despite the fact that I enabled it back after deflating. Its strange, did you have this problem aswell ?
My guess when I checked your video again is that once the tank is full, the vavle closes and then the gallery pressure becomes the pressure in the tubes and no longer the pressure from the tank.
Does anyone have any idea how to soften the suspension? Mine seems hard and can feel every bump.
Not sure, only whay would be to lower the air suspension a bit. Is the car lifted, is it on original air struts, does it have original lower controls arms or HD arms or Polybush?
@@LandRoverDrive It’s all original, I was thinking to hire it to soften it? Shall I change the control arms to poly bush?Thanks for you reply.
@@ArnoldClarke no. dont use polybush on Discovery 3 or 4. As for the hard ride, what are your tyre pressures? and are the tyres old? as old tyres become hard.
@@noelwhittle7922 I sold it, thank you.
