Thread: Gap Diagnostic IID Tool Questions

Great question.
I know a few people who will benefit from this info.
Thanks

2. Now if I have increased the normal height have I also raised the access and off road height by the same amount?
3. In order to decide how many increments to raise the vehicle do I need to use the tape measure to determine what height I want and how many units that equates to?
4. What is a safe amount to raise the normal height by so that I won't top out the suspension if say I get grounded and the car goes into extended mode (assuming that changing the normal height impacts the other heights as well)

Advice on the procedure from anyone who has used the Gap tool for this purpose would be really appreciated. Many thanks

What you use the tool for is to change the height calibration, not the specifically the height as such. That is still controlled by the vehicle.

For instance if you change the height calibration by +50mm, your normal on road height will be recalibrated +50mm higher than before. Once the vehicle detects it is now below its normal on road height calibration it will raise itself an additional +50mm. That additional +50mm is now equivalent to off road height but because the vehicle thinks it is at on road height it will not lower if you exceed 50k/hr

Because all you do is change the height calibration (or height off set) every thing works the same as before. So if you go into off road height it will now be at off road height plus (or minus) the off set you have choosen with the IID tool but it will still lower automatically at 50k/hr.

For safety reason you can not choose greater than +50mm off set.

Hi Mike, i have D3 and i frequently use the IID tool. Your first step should be to email GAP and ask if you can have access to the BETA software. I think they just ask for a simple yes i agree to some terms (beta use is potentially unstable or buggy etc), then plug your tool into your computer and download the installer from their website.

What this does is give you access to a much better height control system, rather than just pushing buttons up or down you can save profiles with names with certain offsets. If you look at the attached pictures you can see it is much better to use.

Basically my sand profile is +40mm above standard height at all times, basically meaning all other height modes (Access, normal, offroad etc) are at +40mm. I drove on fraser island with the car in this mode for a week and only experienced one problem, i got caught on a root and the car wanted to go into extended mode, which then triggered a minor (amber light) suspension fault. Simply cleared it and moved on. I think the fault was caused because the car tried to go into extended mode but reached the height limit for the sensors and triggered the fault. It works fine in low range, if you don't want the height of extended mode (definitely not for high speed driving) just put it back into normal once you change.

Plus it gives quick access to height settings, so you can select extended or bump stop modes from a separate menu (see second picture)

Haven't had any dramas with the BETA software yet.

These pictures are the same as in the current user guide dated 2016-12-12. So the facility may now be live rather than beta if the user guide shows it to be so.

I have written to GAP today to get some additional answers about this very topic. My need is to have a quick way to drop down as low as possible to get SWMBO into or out of the car and then raise back to normal road height to drive away. From what I see you may need to reset the height as per picture 1 and then enable it as per picture 2. I raised simply using go down to bump stops for maximum access height drop which would mean simply pressing normal height to get back to road height quickly. May be a solution. Looking at this and LLAMS but yet to decide.

I think from a convenience point of view, if you have a need to frequently and quickly adjust height as in the scenario you outlined then LAMS is the way to go.

Here is the Q & A result from talking to Patrick at GAP. I have highlighted Patrick's responses in blue. The pages I speak about are the diagram screenshots shown in previous posts.

Reading the instruction manual, this page (1st screenshot) suggests that I can set three heights and effectively use Setting 3 as Access Height. You can set anyone of the 3 settings to your liking, this is just an example with titles I put in.

From my reading if I chose Setting 3 to be say 40mm lower than standard, every other height (normal and off road) would also be
40mm lower than the default. Correct. One must understand that if the standard height is lowered too much, selecting the access height will make the car reach bumpstops thus triggering the extended more (rasing the car...) since the system believe the vehicle is grounded. Adjustments is necessary to get it to the right spot so that extended doesnt trigger.

Conversely, if I set Off Road height 50mm higher the same principal applies, ie access height and normal height would be 50mm higher than default. Is this correct? Yes.

This page (2nd screenshot) seems to be where I would be doing the actual initiation of choosing access or normal mode when I want to physically change height. This actually replicates the car height buttons with the additions of the lowering to bump which is exclusive to us. If for example you cannot adjust the car low enough for your needs using the height function, lowering to bump is an option.

There are 2 solutions as you already noticed:
1. How do I retain normal default height to drive to my destination and then change to adjusted access height without a two-step process? It seems to me that I would need to change to access height first as per diagram 1 and then effect the change via diagram 2 and then reverse the process to get back to normal default height. Of course I am probably misunderstanding how this all works .

-Height screen--Select My Access height, click on program
-Press on the lowering button of the suspension and wait for the car to lower. No need to enter the height control screen.
-Pick up your wife
-Height screen--Select Default
-Drive the car, it will raise itself up automatically

2. Is there any reason then that I cannot leave the heights as normal and simply select option 3 and drop down to bump stops for maximum safe lowering of the car?

Or, if you need to lower it more:

-Height control screen--Select lowering to bump (button 3)
-Pick up your wife
-Height control screen--Standard height (button 2)

Both options can be started a few meters from your wife location to speed things up.

Hope this helps, I just need to clarify the 50 kph lowering issue.

Martin

To achieve what you want you pretty much need the IID tool permanently plugged in unless you want to fiddle about with it all the time.

Ask GAP if they would recommend you leave the IID tool plugged in permanently.

From the IID manual

2.8.6 Disconnecting the IIDTool
The IIDTool was not designed to remain permanently connected to the OBDII port of the vehicle. Disconnect the IIDTool after each use.

Can confirm, definitely does not lower if you set a high offset!
