Term
Explanation
OBDII diagnostic
connector
Standardized hardware interface connector that provides access to the
state of health information for various vehicle sub-systems to perform On-
Board Diagnostics.
ECU programming
The tuning of engine management parameters stocked in an ECU. It can be
carried out in serial communication or in Boot mode, and it substantially
consists in three operations:
Reading the original file stocked in the ECU.
Modifying the original file using a tuning software.
Writing the modified file to the ECU.
Serial
communication
Communication mode with the electronic control unit through the
diagnostic connector of the vehicle (often called OBDII connector).
It can be done:
Via diagnostic connector: with the ECU mounted on the vehicle, simply
by connecting to the diagnostic connector typically located in the
cockpit.
On bench: by disconnecting all wiring and removing the ECU from the
vehicle to connect to its external connector, with no need to open the
ECU.
Note: Not all ECU can be reprogrammed on bench in serial communication.
Boot mode
communication
Communication mode with the electronic control unit in which the ECU
system is started in a particular operating mode; this allows performing
operations normally not possible in serial communication (for ex. reading of
the original file, reading/writing of the EEPROM memory, etc.).
It is usually carried out on bench, with the ECU unplugged from all wiring
and open, as it is necessary to feed some pins of the ECU circuit with a
suitable voltage (often by soldering some wires on the circuit).
It can be done using:
The Infineon Tricore module.
The K4 cable.
Communications
protocol
Language of communication between the tool and the electronic control
unit.
Family
Name given by Alientech Srl to a set of communication protocols used by
KESSv2 to dialog with engine control units communicating in a similar
manner.
Plug-in

that cannot be programmed via the OBDII diagnostic connector.
Pull Up Resistor
Interface resistor, it varies some electrical communicating parameters on
the K-line between the tool and the engine control unit.
Setup
Item of the programming menu of the K-Suite software that allows changing
some communication settings of the tool.
