Abbreviations and Acronyms

The following terms abbreviations and acronyms are used in diagnostic trouble code definitions
displayed by the Scanner, or used in Mercedes literature.
blink code
A type of vehicle control system that has no serial data. Any trouble codes the
control system set are extracted either by flashing the malfunction indicator lamp
(MIL) or using special digitized break-out box.
code A numerical code, generated by the vehicle control system to indicate a fault has
occurred in a particular subsystem, circuit, or part.
cursor The arrow that appears on menus and some other displays. In most displays, the
cursor moves as you scroll.
fix To lock a single line of the display in a fixed position on the screen to prevent it from
scrolling. Data readings remain live while the parameter categories are fixed.
frame One complete data package, or transmission cycle, from a vehicle that provides
serial data of control system operating parameters.
hold
To capture and hold a single data frame for review or printing. Data readings
(measured values) are locked at the frame that is held, while parameter and code
lines can be scrolled. A data frame may be held while selected lines are either fixed
or released.
movie A vehicle data record whose length depends on the number of selected data
parameters.
menu A list of vehicle tests or programs from which a selection can be made. Scroll to
place the cursor at the desired function on a menu and press Y to enter the function.
