This is copied from my Tips for New to Sprinter owners thread.

I've received some inquiries as to Sprinter acronyms and abbreviation abbreviations. Having a separate thread may make this info easier to find.

DRBIII, DAD and some other acronyms which may come up

What specifically does DAD stand for? Not my Dad, cause he's of no use here....
The DAD is Doktor A Diagnostics

It is a fleet purchased aftermarket scan tool which Doktor A supplied at a great low price until the supply dried up. If memory serves it is related to the Carsoft technology. It accesses via K-line communication and will work on 2001 - 2006 (NAS aka NAFTA) T1N Sprinters. It will also work on Euro models with a proper cable adapter. I'm 100% certain that it will not work on any NCV3 models (CAN bus accessed).

DARF (Doktor A Rsn Fix)
A cure for RSN accomplished by drilling a set size bleed orifice for a specific transmission solenoid.

Oh yeah, DRB too....

Dirty Rotten Bastard?

^^^ that's what it means according to
If you can believe this...

"It is the Chrysler(Dodge) factory scan tool. It stands for Diagnostic Readout Box (model 3?). The DRB III was/is used for vehicles up till the 2006 model year." The DRBIII and Sprinters up to NAS aka NAFTA MY 2006 use K-line for scan tool/module communication.

Actually the 2006 reference is incorrect. Many post 2006 Dodge/Chrysler vehicles (non-CAN bus access) still use the DRBIII tool.

Newer generation CAN bus vehicles respond to the StarScan, Wi-Tech or StarMobile tool. I know that the 2007 Sprinters can use those tools. I don't believe later model Sprinters than 2007 do. (Where is Jon Caples when you need him??)

These are all the Same Picture of an Engine on the Dash Warning Light

Names are interchangeable: MIL Malfunction Indicator Light, CEL Check Engine Light, ECU Engine Control Unit as in this page from the manual. (common name used across the pond)

Re: DRBIII, DAD and some other acronyms which may come up

A few suggested add-ins:

D+ Circuit that is powered when engine is running

In converter/inverter/charger/solar discussions:
VAC or Vac Volts, alternating current (such as household wall outlets)
VDC or Vdc Volts, direct current (such as battery voltage)

Amp Amount of electrical current flow
AH (Amp Hour) total amount of energy (an amp flowing for an hour)
W (Watt) Power (volt * amp) (also volt*volt/resistance)(also amp*amp*resistance)

MSW Modified Sine Wave
PSW Pure Sine Wave
PWM Pulse Width Modulated
MPPT maximum power point tracking

Sprinter engine:
IAT Intake Air Temperature (measured after turbo and intercooler)
MAF Mass Air Flow

Found in service manual instructions:
ft-lb Foot-pound (torque measurement: a pound of pressure applied at the end of a one-foot-long lever)
in-lb Inch-pound (smaller units torque measurement)( one ft-lb = 12 in-lb)
N-m Newton-meter (torque measurement) ( one N-m = 0.737 ft-lb = 8.85 in-lb)

kPa kilo Pascals (pressure) ( 1 kPa = 0.145 psi )( 15 psi = 103.4 kPa )(one psi = 6.895 kPa)

bar bar (from "barometer") (pressure) ( one bar = 14.5 psi)
atm atmosphere (pressure) (one atm = 14.696 psi)

(the "D+" shows on your earlier scanned list as "Terminal D+", but that's not where you'd look for it alphabetically)
