ProTool instructions to downgrade Active Cruise Control (w/ radar) to Cruise control with braking

[i3igpete]

These instructions correspond to those of you installing the DivineDrive intake duct, or anyone else that is annoyed by the active cruise being overly cautious, even at its minimum setting. Note that ACC can be disabled by holding the "closer" button the steering wheel, but will re-enable itself on next engine start.

If you're using the MHD universal (red wifi) adapter, you do NOT need to be in airplane mode.
However, make sure:
-Wifi assistant is OFF (this will kick you back to your home wifi if no internet is detected on the MHD adapter)
-Ethernet tethering is OFF.
-Protool is android only, but if they ever port it to iphone, FORGET your car as a carplay device

When using the MHD universal tool with ProTool, the connection needs to be ENET_WIFI, not WIFI. This needs to be selected from the kebab menu (3 dots in the top right) and then "Interface: ENET_WIFI". This is NOT an option from the connection options on the popup/splash window.

Once you are done, the next engine start should NOT have any idrive dings at startup. There is a silent error in the BDC module in ProTool, but it's so deep that BimmerLink doesn't see it.

The code is 30411, which makes sense to me. It detects that the steering wheel has distance control when the car doesn't need it. I suppose if someone had a spare MT steering wheel laying around to install on an AT, in theory they would have no codes at all.





Edit: so after removing the radar module, I have lost Cruise control. It seems that the DME is still performing health checks and looking for the radar sensor, even if it's not used in the vehicle order. My advice is to leave the radar sensor plugged in but zip tied out of the way so that it can still respond to health checks from the DME.

Note that the coding instructions did work perfectly when my radar was still plugged in. normal (non-ACC) cruise control working fine.

If anyone more knowledgeable about coding wants to dig in further, here are the two codes:

CDA038 - No message (information data, cruise control, 71.7.32), receiver DME, transmitter SAS.
CDA059 - Message (information data target object cruise control, 2, 125.0.16) missing, receiver DME, transmitter SAS.

Edit 2: updated with instructions from comment 3. Dynamic cruise control should now work with radar removed, but communication fault remains for now.

The following coding changes might be useful to a general audience that DON'T have the DivineDrive intake duct and DO still have ACC, but want to get rid of some annoying warnings:

and their English translations:


Rear Collision Warning Present -> Disabled
Cross Traffic Alert Present -> Disabled
Lane Keeping Assistant Present -> Disabled
Speed Limit Assist Present -> Disabled
Coasting Consideration for Speed Limit Info -> Disabled


Would like some feedback from folks that have tested this without doing the Vehicle Order changes.

Quick update. Although the original instructions worked perfectly to downgrade ACC on my automatic, the instant I unplugged the radar sensor I got a communication error and the cruise control buttons stopped working. I've been through a few iterations and there are some additional codings that need to be done AFTER you remove your radar. Note that the original instructions will still work if you have your radar sensor still plugged in (for those of you that haven't ordered the intake duct, but simply dislike ACC)

I have not been able to get rid of all the LIN communication errors that show up, though they don't throw a CEL. The following promising coding options I found on Google do NOT exist on the Supra, just so nobody else wastes their time.

To test:

AUFFAHR WARNUNG = Collision front by radar or camera (ibrake or fcw / ccm]

SPURWECHSEL_ WARNUNG = Lane change warning with radar [hc2]

C_SLA_Anzeige_Zusatztexte = Speed Limit Assist - Display Additional Texts

FasCdiEnable = FAS Collision Detection Intervention

FasTplEnable = Target Planner Enable (Lead Vehicle Tracking).

FasQrgDrvEnable = lateral (Steering/Lane Keeping) assistance

C_SLA_Angebot_im_Standby = "offers" (displays) a new speed limit when the cruise control is On but not Engaged (standby)

 

[i3igpete]

The instructions in the first post start by disabling ACC, then selectively turning certain software features off that depend on the radar being there.

Working on a new set of instructions where we disable things in batches using vehicle order, but then selectively change the checks for hardware components are physically installed in the car. BMW Electronics apply a check when commands are received, to see if they match the model of button or switch installed on the car (the linbus variant). We are simply bypassing the check so that all commands are followed.

If this works better i will replace the instructions in the first post. Anyone with elite ball knowledge please correct me before i waste even more time on this. This is a working document because i have like 30 protool and gemini screenshots saved and I'm starting to confuse myself.

Edit:
All turn stalk controls confirmed working.
Wiper stalk controls working, but cant test auto speed selector until it rains
All radio/call controls confirmed working
DCC cruise working as expected (on/off, set, resume/cancel)

This corrects all the linbus errors except one

30492 Steering wheel electronics: unexpected LIN slave

but... I don't know if we can actually get rid of it without swapping the button cluster. Going to call this good to go.

Hell yeah dude, fantastic work 🫶

Based on the following, it would be in 5AG, however we dont have that option. So that means if someone wants to keep lane departure, they would need to leave 5AS on, and selectively turn stuff off to disable front collision. Will explore the protool "add-on" function tomorrow and see what it does.

VO Code	Official Name	Description
5AG	Lane Change Warning	The standalone code for blind spot monitoring. It activates the rear radar sensors and the warning LEDs in the side mirrors.
5AS	Driving Assistant	A safety "bundle" that includes 5AG as a standard feature, along with Lane Departure Warning and Collision Mitigation.
5AT	Driving Assistant Plus	An advanced bundle that includes blind spot monitoring plus Active Cruise Control (ACC).
5AU	Driving Assistant Pro	The most modern suite (G-series) that includes blind spot monitoring, 360-degree radar coverage, and semi-autonomous driving.

(i didnt mean to post this here but fuckit. We were talking about how to get blind spot monitoring back with the latest coding strategy)
