Steering Angle Sensor (SAS) Service
This service function allow you to perform calibration for the Steering Angle
Sensor, which permanently stores the current steering wheel position as the
straight-ahead position in the steering angle sensor EEPROM. On successful
completion of the calibration, the steering angle sensor fault memory is
automatically cleared.
DPF Regeneration Service
The Diesel Particulate Filter service function performs the regeneration
procedure which is the DPF cleaning operation to clear the blockage through
continuous burning of the particulate matter captured in the DPF filter. If the
DPF light on the vehicle comes on and you successfully complete a DPF
regeneration cycle, you will notice that the DPF light will automatically turn off.
4.8 Programming and Coding
Since the introduction of OBD II and leading up to modern Hybrids and EVs,
computers and software in cars have been expanding at an exponential rate.
In-car software is becoming one of the leading needs for service, and updating
software may be the only way to fix some of these issues:
 Drivability
 Fuel Efficiency
 Power Loss
 Fault Codes
 Durability of Mechanical Parts
The Programming and Coding function is used to re-flash the vehicle control
modules, it allows you to update the computer software on the vehicle to the
latest version, as well as to reprogram adaptive data for certain components
after making repairs or replacements.
NOTE: The programming function can only be applied through connection
with the J2534 programming device, which serves as a PassThru interface to
establish communication with and transfer data to the vehicle’s ECU.
Available programming or coding operations vary by the test vehicle, and only
the available operations display in the menu.
There are two general types of programming operations:
