10.4 Diesel Particulate Filter (DPF) Regeneration
DPF Regeneration menu lets you perform the DPF cleaning to clear the
blockage through continuous burning of the particulates captured in the DPF
filter. When a DPF regeneration cycle is completed, the DPF light
automatically goes off.
10.5 Throttle Body Alignment (TPS/TBA)
It’s very common to see a customer pull into the shop with a Volkswagen or
Audi that just will not idle correctly. One of the possible causes is that the
throttle position is not known. When the motion range is not known, the ECU
simply has no idea where to set the throttle. The ECU must know the full
range of motion of the throttle in order for it to properly control the engine.
Using the throttle position sensors in the throttle body, the ECU learns the full
open and full closed positions through various states (idle, part throttle, WOT)
known as a Throttle Body Alignment (TBA).
10.6 Steering Angle Sensor (SAS) Calibration
SAS Calibration menu lets you perform calibration of the Steering Angle
Sensor, which permanently stores the current steering wheel position as
straight-ahead in the sensor EEPROM. On successful calibration of the
sensor, its fault memory is automatically cleared.
10.7 Continuous Variable Transmission (CVT)
This function is used to reset the compensation code and initialize the ECT
after a solenoid valve or valve body assembly has been replaced.
10.8 Gear Learning
The crankshaft position sensor learns crankshaft tooth machining tolerance
and save to the computer to more accurately diagnose engine misfires. If
tooth learning is not performed for a car equipped with Delphi engine, the MIL
turns on after the engine is started. The diagnostic device detects the DTC P
1336 'tooth not learned'. In this case, you must the diagnostic device to
perform tooth learning for the car. After tooth learning is successful, the MIL
turns off.
After the engine ECU, crankshaft position sensor, or crankshaft flywheel is
replaced, or the DTC 'tooth not learned' is present, tooth learning must be
performed.
