3.11 Gear Learning
Crankshaft position sensor adaptive 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 P1336 'tooth not learned'. In this case,
you must use 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.
3.12 Suspension Match
This function is used to adjust car body height.
When the car body height sensor and control module in the air suspension system are replaced
or the car level is incorrect, perform this function to adjust the car body height sensor for
horizontal calibration.
3.13 Sunroof Initialization
This function is used to set sunroof lockup close, close on rainy days, slide/tilt sunroof memory
function, outside temperature threshold, etc.
3.14 Gearbox Match
This function is used to learn the gearbox to improve shift quality.
After the gearbox is dismounted or repaired (after battery powered off for some car series), shift
delay or impact is caused. In this case, perform this function to make the gearbox compensate
automatically according to driving conditions so as to reach more comfortable and ideal shift
quality.
3.15 Ajuste Fuel
Adjust fuel gauge if fuel type is changed.
3.16 Odometer Calibration
Instrument panel mileage calibration is used to copy, write, or rewrite mileages. That is, use the
car diagnostic computer and data line to copy, write, or rewrite chip data on the instrument panel
to make the instrument panel display actual mileages.
Usually, when the vehicle speed sensor is damaged or the mileage is incorrect due to instrument
panel faults, you must perform mileage calibration after maintenance.
3.17 AFS (Adaptive Front Lighting System)
This function is used to initialize the adaptive headlight system. The adaptive headlight system
determines whether to automatically turn on the headlight according to ambient light intensity,
monitors driving speed and body posture, and adjusts the headlight lighting angle.
4 OBDII/EOBD Diagnostics
When Diagnostics application is selected from Home screen, the code reader starts to detect the
communication protocol automatically. Once the connection has been established, a menu that
lists all of the tests available on the identified vehicle displays. Menu options typically include:
●
Read Codes
●
Freeze Frame Data
●
Erase Codes
●
Live Data
