Adaptive Cruise Control - ACC deactivated by diag

[michalzahor]

Hi,

I'm unable to change ACC to active in ABS / ESP . [ using WinXP latest DDT4ALL version ]

Seems like data are writtencorrectly but the value is still "deactivated".

Is the error in the screenshot related to failed write operation ?

[cedricp]

Look like an ELM clone issue. Could you send your log files and report result of ELM benchmark ?

[michalzahor]

attaching logs, ELM bench. was described in another post

[michalzahor]

using Carista Bluetooth module

[cedricp]

The ELM seems to work, are you sure you're using the right XML file for your ECU (did you scan your vehicle ?)

[michalzahor]

Yes, I did.

It shows few red info that xml is not present for ECU and about 2 are not fully ok. But ABS was not mentioned there.

I'll post result of the scan tomorrow.

[cedricp]

Try to increase CAN timeout in the bottom of the application window, and be careful when working on the ABS ECU of your vehicle, safety before all :)

[michalzahor]

Actualy I don’t understand why is there (ABS) status of ACC deacrivated by diag.

What I’m tesing to achieve is to enable ACC and DW ( I’ve koleos where this functionality was available for 0€ but it must be checked during order and it wasn’t ).

I have enabled DW and it is working. But ACC not - I have enabled it every where I found it, except ABS ecu.

Is there some special diag ecu that can keep holding this disabled or is it just diag function of ABS ecu ?

Will try to increate timeout tomorrow and see if I’ll be able to change this setting in ABS ecu.

Thank you

Michal

How old is your koleos? 1 or 2 months? Does it have a radar or advanced camera under the windshield? One of them are required for activating ACC. Simple camera is not enough.

[michalzahor]

Koleos is from end of september 2018. It has RaCam. I’ve enabled distance warning and is working correctly.

I don’t have steering wheel with a button to change a distance for ACC but I think it should work without it.

After I have setup ACC is most ecus ( expect abs there is still “deactivated by diag” ) I’m not able use tempomant ( even basic CC ).

Result of ECU scan

Each recognised ECU with relevant XML should be there listed ? Then the list is kind of short :-)

In the terminal I see Some Warnings during scan process

[michalzahor]

I've tried to increase timeout ( from Auto, to 600ms ) and I was able to write data.

But then check ESP, check hill assist, warning in indicated . When I deactivate ACC in ABS/ESP, then the warning is done.

Seems like somewhere is ACC still considered as not active or prohibited.

After setting ACC activated in (ABS/ESP )

How the parameter looks before activation in ABS/ESP

[shrlnm]

Which changes did you do in radnav?

[michalzahor]

I have modified Rlink fw 7.x only using development menu. In DDT4ALL there is only radnav 2.x and 3.x and I was worried about applying changes using DDT4ALL.

In dev mod I have just enabled ACC in one place - don't remenber now where but it was in the same place where DW ( distance warning ) and DW is working.

Can you suggest other changes ? Is it safe to use radnav in DDT4ALL if my ecu database doesn't have radnav 7.x ?

[shrlnm]

The changes have to be made in Claster, RadNav, ABS/ESP and main changes in RaCam

Using ddt4all is preferable to change configuration in radnav then thru DeveloperSide. And do not remember to reset radnav after changes

[shrlnm]

RadNav_2*.xml is safe for your car

[michalzahor]

1. Is it safe to use for example RAdNat 3.x v3.3 in DDT4ALL if I have RLINK2 firmware 7.xx ? [ I see now your comment about RadNav_2* - ok I'll try use that ]

2. Rlink reset - long press on RLINK ( will go black for few seconds ) is the same as Hard reset ?

[shrlnm]

Yes, long press on power button next to screen is equal to hard reset of radav

Don't know anything about resetting racam. Some ECUs require hard reset for changes take effect.

[shrlnm]

I suggest to save configuration before change something.

[michalzahor]

Is it possible to save current ECU config or just write down original value ?

[cedricp]

The last version creates a file named screens.txt in the log directory. Here you can find old read values.

[michalzahor]

I have do changes but:

Claster - changed 2 values ( don't know name of param, will write down tomorrow )

RadNav - changed 1 value, hard reset

RaCam - using XZG_RaCam_V1_2_20160805T115937.xml - unable to find values with mph, just kmh ( changed kmh values ) - unable to find there 2 in screens, but they are in XML - how can I change that ? AEBS37_VectorFeedBack.P_tng_m_DistVectorFeedBack_1_2, AEBS37_VectorFeedBack.P_tng_m_DistVectorFeedBack_1_1

ABS/ESP - changing to Activated -> I see on dashboard "Check ESP"

Except

AEBS37_VectorFeedBack.P_tng_m_DistVectorFeedBack_1_2, AEBS37_VectorFeedBack.P_tng_m_DistVectorFeedBack_1_1 and mph values

all was changed but doesnt work.

Is it possible that system knows I don't have distance button on the steering wheel and that's why it is blocking activation ?

[shrlnm]

Try to use RaCam_V4_20170703T152858.xml but I not sure that these parameters are available here. If not then you may try to write own script, make own screen in ddt4all or use a pyren it has synthetic screens for every command.

About distance button not sure that ECU may know. These buttons usually made as a resistive set and only two wires toward ECU but I may be wrong

[shrlnm]

In the cluster you need to change only one parameter CCSLACCServiceCustomer_CF from "1" Text="CC/SL" to "2" Text="ACC/SL"

[michalzahor]

I have made custom screens and do the whole process one more time:

1. ddt4all using connected mode

2. choosing XZG - KOLEOS 2

3. RaCAM v4

I have created custom screen also for MPH values and changed ( forget to make a photo ). Just in MPH there is not defined last one variable - DistanceControllerMaxSpeedCommand

Those values are different from you suggested - I'm little bit worried to mess with that - do you think it is related to ACC not operating ?

4. RadNav 2.x

5. Cluster

I have found 2 values in cluster mentioning ACC ( the first one should be not set to ACC ? )

6. ABS

I'm thinking about the text - Deactivated by diag - like in this ABS ecu it should be auto activated if in other ECUs is all ok or some diagnostic returns that ACC can be activated. Maybe can I use function in ddt4all - DTC reset to reset errors if any without any harm ?

[shrlnm]

Did you reload the TDB after changing "1" Text="CC/SL" to "2" Text="ACC/SL" ?

[Banana009]

I tried to activate ACC on my Scenic IV. But without success. It seems that missing some hardware part( different ABS sensors). Look onto previews threads.

[Banana009]

Here: https://github.com/cedricp/ddt4all/issues/47

[michalzahor]

Yes I have reloaded TDB after change and there was ACC/SL

I have part number of RaCam and I'll try get info if it is the same as in the version with ACC enabled.

@Banana009 - can be so, courious if there is some possibility to get info from ECUs why ABS ECU is indicating that ACC was deactivated by diag. - which diag, reason ,etc.
