Adaptive Cruise Control - ACC deactivated by diag #126

michalzahor · 2019-01-02T20:21:51Z

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 · 2019-01-02T20:41:26Z

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

michalzahor · 2019-01-02T20:50:35Z

attaching logs, ELM bench. was described in another post

michalzahor · 2019-01-02T20:51:41Z

using Carista Bluetooth module

cedricp · 2019-01-02T20:56:04Z

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

michalzahor · 2019-01-02T20:58:58Z

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 · 2019-01-02T21:02:22Z

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 · 2019-01-02T21:40:09Z

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 · 2019-01-02T22:55:48Z

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 ). Michal Zahor

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 · 2019-01-03T06:20:29Z

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 · 2019-01-03T08:23:26Z

Which changes did you do in radnav?

michalzahor · 2019-01-03T08:36:08Z

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 · 2019-01-03T08:44:06Z

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 · 2019-01-03T09:07:22Z

RadNav_2*.xml is safe for your car

michalzahor · 2019-01-03T09:07:53Z

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 · 2019-01-03T09:13:19Z

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 · 2019-01-03T09:14:46Z

I suggest to save configuration before change something.

michalzahor · 2019-01-03T09:31:30Z

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

michalzahor · 2019-01-03T17:03:22Z

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 · 2019-01-03T18:47:44Z

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 · 2019-01-03T21:24:02Z

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

michalzahor · 2019-01-04T13:22:02Z

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

ddt4all using connected mode
choosing XZG - KOLEOS 2
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 ?

RadNav 2.x
Cluster

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

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 · 2019-01-04T19:02:37Z

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

Banana009 · 2019-01-04T21:30:46Z

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.

Here: #47

michalzahor · 2019-01-05T08:11:48Z

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.

Banana009 · 2021-01-28T21:57:21Z

Did you replace the second button with a picture of a car? here: https://youtu.be/Uh_v86O3t3Y
There must only be some additional settings in the injection ECU.
For example, to activate ACC on a Skoda car just encode. There is no reason for Renault to have it otherwise. We must continue our investigation....

Hello,
has someone successfully launched ACC on a 1.5 DCI engine?

AndyIreland · 2022-06-21T23:31:40Z

no i havent, but isnt other hardware needed like front camera? or does it use front ultrasonic sensors for active cruise control?

luissilva1971 · 2022-06-22T04:17:00Z

Do you mean that it is not possible to activate in a 1.5 dci 90cv engine cruise control / speed limiter functions? I was wondering to do that in my (adding steering wheel buttons and control button) hoping the cars hss the remaining wiring.... so no go?

sinwe · 2022-06-22T07:04:57Z

It is possible, just not with ddt4all only. You also need canclip along with VIN of another Renault vehicle of the same type as yours that has ACC.
On top of that you also need to have the steering wheel that has the ACC button

Banana009 · 2022-06-22T10:17:29Z

It is not easy. You must have the original Renault Can Clip with a connection to the renault server. Only a few people managed to do it.
Forget that you can activate ACC if you don't have a friend at official Renault servicing facility :-)

luissilva1971 · 2022-06-22T18:04:54Z

Well, no, unfornately, i have not. Just another thing ... AAC = adaptative cruise control, is the same as CC (cruise control "conventional")? or are they 2 diferent things. If different, maybe my car can have CC and for that only need some hardware (buttons on steering whell and switch CC/SP) and ddt4all... Can anyone clarify this please?

Active Cruise Control or Adaptive Cruise Control (ACC) = if cruise control is on but if it detects an object in front of your car (like another car say) then it can disable (hopefully!) the cruise control.

CC = the only thing that will turn off cruise control is if you brake or turn off the CC switch (or press 'mem' on the steering wheel.

So is it possible to include in my car the CC (of course adding steering wheel with buttons and also CC/ SL button selection)?With DDT4all?
From a dump i 've made with Pyren, my ECM is "DCM34_P4C8_X95_L38_B32_V22". On DDT2000/ DDT4all screen for this ECU, and on my "offline" screen, i don't find nothing "regarding RV/LV - Configuration option", just one screen where there is an indication that my vehicle is "without" CC.

TDB has the parameter ... "CLUSTER_X91_L43_L47_Conti_v2.1":

Thank for advice.

i dont really know to be certain sorry if you can . also did you check your TDB cluster dash settings to see if you have the SL/CC bulb in your dash , if you look at speedo a certain way you might be able to see the graphic of the icon:

Yap. There exist both on dashboard. Also clutch and brake sensors.

Only thing I did not yet searched is the plug inside steering wheel for CC buttons, but I believe that also will be there. So in terms of requeriments only things missing are steering wheel with CC buttons, and CC/SP on off button. And of course the right programming of ECUs. That's what I would like to learn to make this upgrade.

Hi, i know everyone here is trying to activate ACC, but is it possible to disable it and have regular CC? I absolutely hate the ACC feature as it slows the car down way too early, even when adjusting the distance.

Hello everybody,
guys, can you please help me .. After some settings made by a friend; multisense activation, start without pedal, update of the intrnatement to 9, something went wrong and the cruise control does not work, sometimes, before the start if I press the button the active regulator screen appears but then in gear it disappears and obviously not working..
I started to get interested and I also have an ELM, I can navigate in the ECU and I tried to follow
these indication

Honestly I didn't understand if it worked in ACC or CC before but I'm sure it slowed down if I got very close to a car in front of me, often even when overtaking, yes, it rang and slowed down ..

I would like to understand if the possibility exists. through DDT4 to completely reset everything and then redo the steps of the changes that interest me ..
Heartfelt thanks and congratulations to everyone.
Lucas,

i dont think its possible to reset all the values, this is why its very important to take screenshots or video of what you are changing. I could be wrong though.

@alex2900512 @lucassssmi pyren allows to save configuration (dump) of all ecus for further comparison and rollback original configuration.
If the dump wasn't taken before any changes then the default dump may be generated by the vin.

lucassssmi · 2022-11-07T09:35:14Z

I saved this files before my change setting .. but i can't understand how using..

By DDT4 it's possible only open xml or create a new ECU ... ?

How it’s possible to generate a standard dump from the VIN?
