Hi,

@Gremlin: Thank you!

Does anyone have a list showing which engine types are compatible with each generation of the EDC system? I assume that all engines using VE systems are at most EDC15, is that correct?

Best regards,

Jan.

It's not quite simple.

VP37 modules in passenger cars are likely to be mostly of the EDC-15 type (excluding older models).

However, the EDC-15 can also support PD and CR technologies, so it's not easy to say definitively. Since it's vehicle manufacturer-specific, you'll likely have to search through the Bosch online catalog.

Hi!

thank you again

Regarding the ABS control unit, I should be able to provide more information in the next few days, as it's scheduled to arrive then. Once it arrives, I'll take it apart to examine it.

For just one euro, you can't really go wrong.

Best regards,

Jan.

You should actually find two processors inside .

Hi,

2 CPUs for one euro, not bad, right?

"To be honest, I'm not really surprised; an ABS control unit should have some level of redundancy."

I don't know exactly what the year of manufacture and type of this ABS is, so it would probably be pointless to guess what's actually inside, but we will find out soon .

Best regards,

Jan.

Hello everyone,

My package arrived, and now the disassembled item is lying in front of me.

It's an ABS unit, likely from a previous generation Golf 3 (model number 1H0 907 379D, now superseded by ...375), which, according to the markings on the chips, either comes from Teves or uses Teves software.

Gremlin is correct; there are two CPUs inside, specifically MHS 83C154 controllers from the 80C51 family, likely with 16KB of ROM and 256 bytes of RAM.

"On the two EEPROMs, besides "TEVES" and some (unsearchable) data, one of the other chips is from Siemens Austria, and one has been deliberately ground down so that its markings cannot be read."

For those who are curious... I've attached the pictures.

Does anyone happen to have information about the pin configuration of this part? It's probably possible to find that in the wiring diagrams for a Golf or Polo, but before I try looking there, I thought I'd ask if anyone knows offhand.

Best regards,

Jan.

P.S.: Just to be clear: I have no intention of installing this modified engine control unit in any car; it is solely for diagnostic purposes.

1H0 907 379 is replaced by 1H0 907 379 B and later replaced by 1H0 907 379 D.

It is an ITT Mark 04, formerly known as a Teves 04.

In this case, it's a pure ABS system, without Electronic Stability Control (ESC).

This part was originally installed in the Corrado, Golf (1992-1995), Golf Cabriolet (1994-1998), and Passat 35i.

Ideally, only functions 01, 02, 05, and 06 should be accessible through the self-diagnosis feature.

Hi,

Thank you very much!

That's exactly what I was looking for; it should be perfectly sufficient to get this thing up and running for its intended purpose.

I will provide further updates later.

Best regards,

Jan.

If you want to test custom-built interfaces, get the problem cases, and then you'll also have fun .

Although there are problem children that I wouldn't want to deal with... for example, a speed limiter device.

Hi,

"No, I'm more interested in the technology of the control unit itself than in the diagnostics (although that's also important, but not my primary focus). To get meaningful insights from interfaces, you would probably need more than just one control unit."

Best regards,

Jan.

My MSG and ABS modules should be on their way; the post office sends its regards...
What is the pinout configuration for an MSG connector, and where can I find that information?

Which one?

Um, I also need something like that for mine.
VW part number 811 906 264, BOSCH part number 0 280 800 104 (105).
I'm not sure if there is a diagnostic possibility .

While we're at it, I need a part number for a diagnostic connector.
My desk is a complete mess, and I want to tidy it up now.

Current test environment:

Engine Control Unit (ECU) for Volkswagen Golf 3, part number: ABS.
Audi ZV/DWA/FFB control unit.
Audi interior monitoring.
Combination instrument panels for VW Golf 4 / Passat.

MSG 032 906 030 from a Volkswagen Golf III.
Airbag control unit, also for VW Golf 3.

Perhaps another MSG (Motor Control Unit) from a Polo will be added.

Okay, the first control unit is right here in front of me. It's an airbag control unit.

Type: 1H0 959 656

The device contains a Motorola IC (ZC408999CFNA), a Siemens IC (TLE4261, a 5V voltage regulator), and another component labeled 'SA20' which is part of a 'loose mass' (crash sensor).

Does anyone know the pinout configuration for this control unit (STG) offhand, or have any more information about it?
