As BENZ’s becoming increasingly more complex with with newer complex, digital control electronics, electrical systems, newer ujanja is always needed to fix, sort out certain ujinga!
This is about BENZ Keys (immobilizer systems),
and related Control Units (ECU)!
For longer, exorbitant, ujanja about keys,
including how to reset (virginize) systems to accept the first key used after being virginized,
or
how to forever disable or immo off to always accept any keys used!

We compile ECU PINOUTS for every all BENZ ECU’s, Electronic Control Units!
These are BENZ’s details of about which pin on the ECU connector, specific function, (e.g., ground, power, sensor input, actuator output) carried by each pin.
These BENZ’ diagrams help you identify if a problem is with a sensor, a wiring harness or the ECU itself,

HAPA UJANJA tu🤠!
Yes, as You know, the immobilizer or anti-theft system verifies that the key used to turn the engine on is the correct one.
If the key is not the correct one, this system blocks different actions to prevent the car from starting, seen🤔?
The car’s computer will disable, the fuel pump, gears’ transmission, the ignition coil and/or the injectors, and depending on the electronic immobilizer system, it could also block the steering column which will lock the steering wheel.
When this system is activated, a warning light such as👇 will turn on!
This is JUST summarizing random points about BENZ keys,
for longer extreme details, check ☝☝check hapo juu!
All that mambo jambo, transponders, readers’ coils, immu immo, this that box, everything uko☝☝!
(We’re disorganized, and so are these👇summaries)
Some useless PDF documents are attached below the page!
ONYO📌
SMART, MAYBACK, SOZI, and may be some others like FreighLiner, Fuso, We don’t know, may be have some ‘zigzag’ relationship with BENZ!
So, You could find some carry-over technology, seen?
NOTE🍻
The MASAI😜 who make Mercedes Benz,
just like other several major MAASAI😉 vehicle manufacturers,
are known for using, words, slogans, names, in their native MASAI 😎language, even in international markets,
probably to emphasize the “Babylon-ness”🤪 engineering quality of their products.
So, You may find different words meaning the same thing🤷♂️!
Electronic Ignition Switch (EIS) in Luo language,
while it’s
Elektronischer ZündstartSchalteror (EZS) in Masai language!
Electronic Steering Lock (ESL) in Luo language,
while it’s
Elektrische LenkungsVerriegelung (ELV) in Masai language!
FahrBerechtigungsSystem (FBS)
in the Masai language, is
Drive Authorization System(DAS),
in Luo langauage!
FahrBerechtigungsSystem (FBS) is the
Drive Authorization System (DAS),
not confuse it with the,
Diagnosis Assistance System (DAS),
And again, by DAS, it’s NOT about Mercedes’
Dual Axis Steering (DAS)🤔!
Just FYI📚, this kind of DAS steering magic allows drivers to adjust the front wheel’s toe angle by pulling or pushing the steering wheel on straights😳,
eventually and effectively, changing chassis geometry mid-race for better tire management and speed.
Seen🤔?
Ok, continuing with IFZ (Infrarot Zentralverriegelung) the Infrared control unit (N54) just like that😉!
In fact THIS useless kit could be useful showing certain components on certain Mercedes Benz’s !

Sasa, because some BENZ keys are made using Infrared (IR), while others, radio waves (RF) technology🧷!
You should remember that;
Infrared (IR) communication requires a direct line of sight between the transmitter and the receiver👌!
The radio waves(RF) can pass through walls, almost any other barriers🧐.
That’s why some BENZ (remote) keys only work,
if directly pointing at that ZNEB🤐!
Mercedes Benz‘s ‘ujinga’ is known as;
DAS, Drive Authorization System!
This DAS has the🤔;
Vehicle Access function to manages locking and unlocking the vehicle doors and trunk using radio frequency (RF) signals (or infrared).
This provides keyless entry or remote central locking ‘ujinga’👌!
Engine Starting, in fact, the immobilizer function which electronically validates the key to ensure it belongs to that specific vehicle.
And this is the nonsense we’re here for, insha’Allah🤞!
When a valid key, P, is detected, a coded data exchange occurs between this key,
and
the N73 Electronic Ignition Switch (EIS /EZS),
and
the N3/9 or N3/10 but the Engine Control Module (ECM), and other relevant control units.
Only after all components successfully agree on the authorization code is the engine allowed to start.
BENZ’s immobilizer system, DAS, has versions, DAS1, DAS2, DAS3, DAS4, DAS5, DAS10000😁😂!
Anyway😳, DAS evolves from the simple & easy ‘Hakuna Matata’, DAS-1!
When👇 the correct key, A, turns the door-lock switch, B, a signal is sent to the Pneumatic System Equipment Pump (PSE), C, controller, to unlock the doors, at the same time enabling the immo relay, D, that is linked to the Engine Starter🤷♂️!
See how why some Benz, without first unlocking the driver’s door lock, NO engine crank🤷♂️!
The Mercedes-Benz’s PSE (Pneumatic System Equipment) pump is some central vacuum pump, controlling door locks, soft-close functions, the boot ama trunk release, and so much, but operating via vacuum lines🤷♂️!
Insha’Allah, wherever the the relay could be located, just imagine one of it’s terminals linked to, and, enabled by the PSE controller😂😁!
This HERE, is some magic for Calculating certain😎,
Mercedes Benz’s DAS (Diagnosis Assistance System),
and or, XENTRY passwords🤐!
This nonsense HERE could help You generate codes for advanced functions, like Adaptation, SCN Coding, etc, that requires specific vehicle data (VIN, ECU info)👌!
So, THIS is some HAPA UJANJA tu 🤪to bypass zyx for xyz functions like EGR, DPF, and other Benz’s Data resets😉!

This was the default DAS-1!
Just the door-lock switch connected to the PSE module, controlling the Stater relay!
For now, the engine ECU is not yet involved, in validating the key!The DAS-1 would later be improved to using Infrared keys!
👇
A 👇unique infrared signal, H, would be received then decoded by the receiver, 2B, then forwarded to the IRC module, J, for validation!
👇
If the key is valid, signals are sent to allow the respective relays, D and 2D, to do their thing!
For now, the engine ECU is not yet involved, in validating the key!
L) Any controllable system that could be simply be integrated as part of the drive authorization system!
In some DAS-1, the engine ECU is later involved in validating the key🤷♀️!
There are many variations of this DAS-1 blaa bla, just fooling about the same similar nonsense🤪
DAS-2
Longer story shorter,
DAS-2 is where involve with transponders‘ nonsense started🤷♂️!
The engine ECU is now more than 10000% involved in the key’s verification!
L) Any other controllable system could also be involved!
Assuming You already passed by HERE to familiarize with transponders, with how they work and whatever ‘ujinga’ involved!!
Back to our DAS-2 story,
the key, A, spits out the infrared signal, H, but just for car access verification!
The Engine start verification is in M, the transponder chip, verified at the ignition-switch🧐!
There are so many DAS-2 variations,
but all play about with the same similar nonsense🚽!
For example;
In some Benz settings, the module, J, needs both the Vehicle-access & Engine-Start verification to be validly, clean👌!
Like🤔,
You locked the door, using the InfraRed,
but now, maybe without unlocking to open the door, You jumped into this Benz, via the sun-roof😜!
Yes, You have a valid key with correct transponder, M, but the Engine will NOT be allowed to start🤷♂️,
unless You first unlock the door via the infrared, H!
The programming is H and 2H, NOT, 2H with or without H😁😂😁
The two departments,
Vehicle Access & Engine Starting,
in some BENZ settings, they depend on each other!
In other BENZ settings, they are independent of each other!
Like, J, could allow Engine-Start with just a valid, 2H, transponder🤷♀️!
Otherwise the annoying warnings in the back mirrors😉!
Remember, it’s NOT just a singular factory defect, but seems a systemic weaknesses in those generations of certain Mercedes Benz to be fond of that “Start Error“!
Click HERE, solve that ‘ujinga’ found on especially likes of, Vito, ML, A-Class, Sprinter, and some other models!
This nonsense HERE could be use, sorting out that ‘ujinga’ that often points to common electrical/immobilizer issues!
DAS-3
All this mechanical ‘analog’ 😁 setup in DAS-2, DAS-3 completely eliminated the mechanical tumblers in at the ignition switch, into the EIS /EZS👌!
The ESL / ELV further toughened the security😎!
DAS-3 started as just this simple🤠!
In DAS-3, the EIS (N73) EZS took over the work of the Infrared Remote Central Locking (RCL) control module, N54, in the DAS-2!
Try to imagine the DAS3‘s EIS like those
simple, engine-start modules in DAS2!
In DAS-3, the security data was further spread to include in the ESL/ELV📌!
P) Most DAS-3 keys are InfraRed (IR),
and some few DAS-3 keys are, Radio frequency (RF)
DAS-4
DAS4 is what makes other BENZ’s everything wireless and more security complicated!
Just imagine the DAS-3 configuration🤔,
but with DAS-4 keys, A2 or A3, strictly of Radio Frequency RF, enabling the keyless entry function👌!
Sometimes, using the number digits on a BENZ’s keyfob, could help seperate a DAS-3 keyfob, from a DAS-4’s!
In DAS-4, including the TCM, ESL, ECU, and EIS, any other system’s module could randomly be included in the Engine-Start enable process!
With recent Mercedes Benz’s enhanced security, while attempting to do some kind of ECU programming 🤔..
..or,
in fact, like key programming could require an internet connection to retrieve data, and or authorization through 💻 Benz’ factory’s computers in their MASAILAND, a.k.a, Deutschland🤠!
Recent Mercedes Benz keys use some advanced type rolling codes that change with every use👌.
So, the online 💻connection allows the programming tool to communicate with Mercedes💻Benz’s computers in Deutschland to obtain the unique, encrypted data necessary to pair a new key with a specific vehicle’s Electronic Ignition Switch (EIS) module.
This online check-up prevents unauthorized key cloning, or any car hacking, significantly securing this Benz🔑!
As we discussed about that unique VIN-Specific Data, where each new key must be uniquely tied to a specific vehicle’s VIN (Vehicle Identification Number).
The online connection ensures that the correct, specific data file for that exact VIN is downloaded and written to the new key, rather than using generic or copied data.
Obviously, ‘kama kawa’ 🍻 the process of programming a new BENZ key involves securely de-authorizing any lost or stolen keys from the car’s memory via the online connection, which invalidates the Lost Keys, rendering them useless if they fall into the wrong hands🤷♂️!
