ECU stands for an electronic
control unit. It forms a part of an automotive electronics system and
controls multiple vehicle subsystems. These subsystems can include
braking, transmission, powertrain, body controls, suspension, timing
and more. ECU’s run on built-in software that continually develops
in terms of sophistication and line count, making them an
increasingly-challenging series of components.
The Programming Process
ECU programming involves a suite of diagnostics software for such ECU brands as Continental, BOSCH, Siemens, Delphi, KEFICO and more. These programming tools write and read ECUs on bench, by diagnostics or through boot mode.
Reading Through Diagnostics
This type of ECU programming
bypasses the need to dismantle the vehicle, making it a much more
direct and time-saving way to read from units that may be hard to
reach. The process involves writing and reading according to the
OBD-II interface and includes real reading and virtual reading from
DataFlash, ProgramFlash, BootLoader and MAP Tables.
By using a ZN051 Distribution
Box, specially made with diagrams for an ECU, a user can directly
connect to an ECU that already been removed from a vehicle. The
connection can be made without soldering or opening the unit.
In the rare instance an ECU
won’t read on bench or through diagnostics, the ECU programming
tool will operate through boot mode and support reading from any ECU
that carries a TC17xx processor. Provided photos and diagrams show
where the boot pin should be soldered.
A Dedicated ECU Diagnostics
The AVDI is a combination of software based on a PC operating system and a hardware interface. It’s capable of reading and clearing live values, trouble codes, actuator testing and other basic diagnostics and features unique special functions, including module adaption, key programming, cluster calibration and more. The AVDI is the top choice for such professionals as repair and service shops, locksmiths or OEM representatives during the completion of system diagnostics. Contact Abrites USA today.
