Hi all.
Here screenshot from my Terrain Response module data.
I have couple questions about that. How to read that? I mean mode1.
1) Distance is 125000km, this is clear. But what about time spent? 24m? Is that mean 24 monts? Engine running in mode1 24 monts? If it so, its a lot, around 17000 working hours. Or it calculate some other time as well there?
2) 24 monts = 2 years. Why it show 24m but 0y? It should show 2y and 0m, or what?

Can anyone explayn?

It will all mean something to someone but if everything is working then don't worry about it....

At times all fatties throw faults that are shown as happening in the future... no rhyme or reason to it......

Don't forget..... It's a Land Rover....  Pete

...Its Land Rover...
I agree, but thats not the answer.
Are IIDTool able to read milage and operational hours from Terrain Control Module?
If yes, can anyone check what his car show?

Yep, IID can read it. I’ll plug in and take a look tomorrow.

So on the IID tool it reports it in seconds. Here’s mine

Great info! Thanks!
Now I can compare and analyse.
Seems its calculate in "time spent" something else, not engine working hours.
Your Mode1 for example: 55000 hours. There in no engine in the world that works so long time. Average speed in this case is 3,4km/h only. This is not possible.
Also look at the Mode5: 15 hours and 1km only. Iam pretty sure you not let engine just running for 15h.
Interesting what mean "time spent in mode.."? What time they talking about?

From the 'Ride and Handling Optimization Description and Operation' section on Topix

Quote:

The Terrain Response control module stores information on detected Terrain Response faults and CAN errors which can be interrogated using an approved Land Rover diagnostic system. The Terrain Response sub-systems and the instrument cluster also store fault information relating to CAN errors from the Terrain Response control module.
The control module also stores the miles traveled and time elapsed in high range for the individual programs and in low
range for use of all programs which can also be retrieved using an Land Rover approved diagnostic system. This
information aids diagnosis of the Terrain Response system and also provides an indication of Terrain Response system
abuse by the driver which can lead to premature component failure.

No, 55000 hours is a lot (if we talking about working hours). 12 year old car and half of that in use??? Are you joking? If drive in 50/50 cycle (city/highway) you should have average speed around 30km/h. 30km x 6 years (ok, lets take 1 year off to get off those 20min) = 1 300 000km.
There is something else calculated as well, not only using time + 20min before sleep. Car just unlocked or something like that...
I had 10 years old Grand Cherokee with 180 000km milage, and computer show only 5000h (compare now with 55000h) engine running time in 35km/h average speed.
But yes, there is no practical application with that info, unfortunately.

But is there in ECM some hours readings maybe, no?

You can't compare the programming across manufacturers that don't have a single system in common.
Without knowing the bounds, it's impossible to say 'what' is incrementing the time in mode, but it is possible to say that it will be the same across all modes so therefore it will achieve the aim of comparative use.
On that note, I'll leave you to it.

I compare the programming across manufacturers due you say 55000h is not that much. 12h per day 24/7 is a lot. Even taxy with multiple drivers cant achieve that amount. That was my thread.

But luckily we know now, this value is not show any "working hours" or "car using hours". Even not "using + 20min" for sure. Useless ino, I agree with you.

The quote from the WSM refers to elapsed time which probably includes switched-off time for whatever mode was in use when the ignition was switched off, only terminated when a new mode is selected, either automatically or manually, on the next start-up.

Interesting, is it possible to read engine working hours from somewhere?

I had a look at mine's distances travelled: mode 2: 359 km, mode 3: 239 km, mode 4: 8 km and mode 5: 144 km.
It appears that the distances for modes 4 and 5 aren't in the sequence of mode selection as I haven't travelled 144 km in rock-crawl and only 8 km in sand mode whereas 8 km in rock-crawl and 144 km in sand mode are conceivable. I can't vouch for the GGS and mud/ruts as I've used both often enough. Overall the special modes haven't had much use in the 160K kms travelled.
Edit: The sequence is indeed the same as the selection sequence. The owners manual is out of step showing sand mode before rock crawl.

Yes, seems you are right. Mine the same.
