Pre-requisites:


Drive Assistence package (Lane Departure warning, High Beam Assistence)



What we did so far:


1) 8TH to VO
2) HU_CIC, 3001 EXBOX, SPEEDLIMIT_INFO = aktiv
3) KOMBI, 3000 Anzeige_Konfiguration, SPEED LIMIT GENERATION = sli_gen2
4) KOMBI, 3003 FZG_Ausstattung, SPEED_LIMIT = aktiv
5) KAFAS, 3010 SLI_CODING, SLI_ON_OFF = SLI_ON
6) KAFAS, 3010 SLI_CODING, CODE_ELECTRIC_HORIZON = nicht_aktiv
7) KAFAS, 3010 SLI_CODING, Country_code_display = wert_3
8) KAFAS, 3010 SLI_CODING, UNIT DISPLAY = wert_4
9) KAFAS, 3020 KAFAS_COMMON, COUNTRY_VARIATION = wert_3
10) Turned on Speed Limit Info in the display.


This wil read speed limits once in a while but the speed limit info stays for few seconds only...

enabling CODE_ELECTRIC_HORIZON makes the icon stay permanently but the car stops reading the speed limits. All our cars comes with CEH active whihc gives us a feeling that it must me activ and there are osme other dependent parameters whihc are required to be configured

I added 8TH to my VO and this is what e-sys changed:

HU_CIC
3001 SPEEDLIMIT_INFO aktiv

ICM - no changes

HUD - no changes

Kombi
3000 SPEED_LIMIT aktiv
3000 SPEED_LIMIT_GENERATION inaktiv
3004 RCOG_TRSG_TIMEOUT aktiv
3004 RCOG_TRSG_APPL aktiv
3008 KI_PIA_SPEED_LIMIT aktiv
3008 HUD_PIA_SPEED_LIM aktiv

KAFAS
3010 SLI_ON_OFF SLI_ON
3010 CODE_ELECTRIC_HORIZON aktiv
3010 Country_code_display wert_3
3010 UNIT DISPLAY wert_4
3020 COUNTRY_VARIATION wert_3

I already updated KAFAS to the latest version, now I'm doing ICM.

If you have KAFAS Camera for HBA, and not the newer cheaper / dumber FLA Camera, it should be capable of being coded to do SLI, and LDW; however, SLI also requires a 7E FSC Enabling Code before it can work, and LDW will work, but you will be missing the Dash Switch for it, and the Steering Wheel Vibrator.

It works!!!

Guys it works, i am very happy :thumbup:

First of all I would like to thank Shawnsheridan for his support when I felt in trouble..
and then also DreamCar for his valuable guidance in this thread...
and finally Americanrider because it gave me hope that the coding would work (without FSC Code) on the first F10/11 series

I state that my car (F11) was produced in September 2010, and among the options present from the factory there is 05AD (LDW system)

I made the following encodings largely following the directions posted by DreamCar

1) 8TH to VO
2) HU_CIC, 3001 EXBOX, SPEEDLIMIT_INFO = aktiv
3) KOMBI, 3000 Anzeige_Konfiguration, SPEED LIMIT GENERATION = inaktive (this item had not changed for forgetfulness, and remained so)
4) KOMBI, 3000 FZG_Ausstattung, SPEED_LIMIT = aktiv (i have not 3003 FZG_Ausstattung, SPEED_LIMIT)
5) KAFAS, 3010 SLI_CODING, SLI_ON_OFF = SLI_ON
6) KAFAS, 3010 SLI_CODING, CODE_ELECTRIC_HORIZON = aktiv
7) KAFAS, 3010 SLI_CODING, Country_coding_display = wert_1 (i have not Country_code_display)
8) KAFAS, 3010 SLI_CODING, UNIT DISPLAY = wert_4
9) KAFAS, 3020 KAFAS_COMMON, COUNTRY_VARIATION = wert_01
10) Turned on Speed Limit Info in the display.

When I turn on the car, you see (on HUD and dashboard) the circle with three "---"
After a few hundred meters the car displays the speed limit
The signal remains fixed until it detects a new limit
I'm sure the KAFAS camera works because it has detected a speed limit recently installed due to roadworks

Now a couple of questions:

> It is normal that when I turn on the car, i see (on HUD and dashboard) the circle with three "---" ?
> I have to correct the entry "3) KOMBI, 3000 Anzeige_Konfiguration, SPEED LIMIT GENERATION" with "sli_gen1"? (I assume is 1 because my car is the first series)

thank you to all

Andrea

I have a F18 (2013),and Can I according to this step to code for SPEED LIMIT INFO in my car without FSC Code

:thumbup:

While your car is an early F11 build, does it have the factory original programming, or has it been updated? What is your I-Step Current?
 
#210 ·
So, as I suspected, you have very old KAFAS firmware, 2.39.x. I do not think it will work if flashed with new firmware.
 
#213 ·
I think if you get flashed with new firmware, it will require a 7E FSC Enabling Code afterwards, just like BMW did with 6NR BMW Apps,
 
#215 ·
I do not understand what you write.

When 6NR BMW Apps first came out, no FSC Enabling Code was needed. Then in a newer version of ISTA/P, BMW added the requirement for a a 9C FSC Enabling Code in Head Unit.

With SLI, they did the same thing. At first, no FSC Enabling Code was needed. Then in a newer version of ISTA/P, BMW added the requirement for a a 7E FSC Enabling Code in KAFAS.
 
#217 ·
On your car, you should be able too, assuming you have a Combox. Add 6NR to FA, and VO Code Combox and CIC. If you older MULF module instead, which came on the earliest wave of F10 builds, it won't work.
 
#222 ·
If you have E-Sys, just Read SVT and see if KAFAS ECU is present.

But, generally speaking, if you have no LDW and you have no SLI, then you have no KAFAS, unless you have a very early build F10, which is before they had the cheaper standalone FLA Camera for HBA Only cars.
