CANBUS is just that - Controller Area Network. It's a bus design, so "CANBUS". All modern Mercedes have at least two and most have three.

R171 has three, 500kbps CAN-D, 125kbps CAN-C, and 83kbps CAN-B. Diagnostic, Engine & Safety, and Interior respectively.

Others i have a little trouble with:
Maf=mass air flow - a measure of how much air is entering your engine
map=manifold absolute pressure - a measure of boost pressure (turbo or supercharged) over atmospheric.
Canbus=what john said.

OBD connector= ? On Board Diagnostics (a connector where you can plug in a Star Diagnostic System or code reader etc.)

PSE Pump - Pneumatic Support Equipment.- a vacuum pump used to operate central locking on various Mercedes models.
