Hello everyone!
I have a problem with a 2006 S/C L322 with all ABS, HDC, and related lights on, loads of fault codes for lost communication between modules but main ones are RH front and rear speed sensor circuits fault.
Both these sensor were replaced, yesterday I tested for continuity and circuit seems fine from the sensor connection on wheel arch to the pin in ABS module.
What puzzles me is that I am looking the diagrams I find two different ABS related modules - one is ECU-ABS (D125), and the other one is ABS module (D277).
The ABS module itself is the one sitting left of the engine with the fluid pipes on it, and this is where I have continuity from the speed sensor connections (D277).
My question is what are these D125 and D277 referring to and what is what? Seems a bit confusing.
Attached is the ABS diagram downloaded from TOPix.
