Windows Diagnostic Platform GT90 Max User's Manual V1.01
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).
6.6 Steering Angle Sensor (SAS) Calibration
SAS Calibration
menu let 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.
6.7 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.
6.8 Gear Learning
The crankshaft position sensor learns crankshaft tooth machining tolerance
and saves 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.
6.9 TPMS Relearn
After the tire pressure MIL turns on and maintenance is performed, the tire
pressure resetting function must be performed to reset tire pressure and turn
off the tire pressure MIL.
6.10 Odometer
This function allows you to revise the date of odometer and write the original
date into new odometer.
