Just wondering if anybody happens to know the security code for the central electronics module. I will be contacting Ross-Tech to hopefully get the code, if no one happens to know it. I will also update the post, if Ross-Tech provides it for future reference.

What are you trying to do?

jlbell

Trying to see what adaptations are available. The central electronics controls the majority of lighting systems in our car. Specifically, I would like to add the double beep unlock tone. I have tried in central convenience but have had no luck. I can turn off both the lock and unlock turn signal flash and lock beep but I can not get a double beep unlock tone. So I figured I would take a look into the central electronics adaptations.

not all controllers have the function

Here you go knock yourself out, dont blow up the car lol thats all functions available on the D3 CE Unit

Coding the control unit / 09 - Central Electric
The code is composed as follows:




*Applies only to vehicles up to and including part number index E
**Sensor -G399 is coded in the roof electronics control unit -J528
***Only if daylight driving lights coded (3rd digit from right = 1)

Abbreviations:
MMI: Multi Media Interface
AUTO: Automatic driving lights (identifiable by light switch) with light sensor
AFS = Advanced Front lighting System

Coding example: 0000001
Blank, footwell light fitted as lamp, halogen headlights / halogen headlights without automatic driving lights, without daytime running lights (AUTO), without daytime running lights, daytime running lights not selectable via MMI, Rest of the World

Reading measured value block

When the ignition is switched on the following input signal for terminal 15 is generated by the Group convenience system data bus in the onboard power supply control unit -J519:

Measured value block 013:

Display zone 2:
Terminal 15 (off/on/no communication)

Basic setting

Procedure:

After replacing the vehicle voltage control unit -J519, the steering column adjustment mechanism and steering column adjustment components*, a basic setting of the two steering column adjuster motors -V123 (vertical) and -V124 (horizontal) must be carried out.

To do so, choose the basic setting function 04 and then channel 001 and activate the basic setting.

* When replacing the steering column adjuster or components of it, be sure to approach its four end positions (up, down, forward and back) with the steering column adjustment switch -E167 before performing the basic setting.

This is all good information, however I am looking for the security access code to access the adaptions for central electronics.

Mister Bally

Top secret. Dealer access only. Sorry. Bring money.

jlbell

Actually the dealer access only is through ODIS, whatever that stands for, which is the factory scan tool. Turns out they do not even provide the security access codes to dealers but rather they are automatically supplied when accessed by ODIS, per an email to erWin USA. Its quite annoying to be honest. I also contacted Auto Logic and they stated they do have access to security codes but you need an Auto Logic Scan tool, which is way to pricey. I might have to get my mechanic to contact them, since he has like 3 of their tools.

Shamoye Lewis

what Im trying to say is the module cant do what you want even if you have the code.... I have dealer access, Im telling you whats up.....
