    Problem with DIS and 635CSI

    Hello. I have a JAP 635CSI, excellent condition. And I also have DIS with ADS support that works great. But, the diagnostic connector is the old type (15 pin) and I have a original adapter (15 pin to 20 pin). Sadly, it doesn't recognize the car. Do I need a older DIS or something else? Modic?

    As far as I know, the E24 has the old style diagnostic plug. BMW DIS and MoDiC are for cars designed after 1988 (facelift E30, E34, E32...). For the old cars, there was a huge diagnostic machine called the BMW Service Test (SUN 2013 Motortester). It was a huge computer with programs loaded through diskettes that was standard equipment for dealers at the end of the 70's. It was the only machine that can read that cars, and was used well up to the end of the 90's with several updates, although BMW DIS started to substitute it at the beginning of the 90s but with no support for pre-88 cars.

    So what do the guys that "rebuild" the early computers use to test or analyze them? Or do they just scope sections and check voltages, components etc...

    I wonder where those big dinosaur machines ended up? Very cool computer btw.

    They could read error memory on some pre-88 models. The screen in the left is a microfiche reader, where the mechanic could read the workshop manual and the nominal values for measures. The middle screen is the computer screen, it shows the BMW Diagnose program. It could read errors from memory, actuate some components individually with engine off, and measure values as a voltmeter with several adapters for the ECU and other units. In older moderls you could attach to it vacuum tubes, voltage probes etc and do the readings for engine parameters measuring in the traditional way. The right screen is the oscilloscope for testing ignition and so on. It has even a printer to print error codes and ECU info to make warranty exchanges. Also, the very first MoDiC was loaded through this monster, with the aid of a serial RS232 cable.

    Very impressive diagnostic hardware indeed, very different to today. Imagine dragging one of those along instead of your laptop and an OBD-cable.
