7.11 Electronic Throttle Position Reset
This function enables you to make initial settings to throttle actuators and returns
the “learned” values stored on ECU to the default state. Doing so can accurately
control the actions of regulating throttle (or idle engine) to adjust the amount of
air intake.
7.12 Gearbox Matching
1. This function can complete the gearbox self-learning to improve gear shifting
quality.
2. When the gearbox is disassembled or repaired (after some of the car battery
is powered off), it will lead to shift delay or impact problem. In this case, this
function needs to be done so that the gearbox can automatically compensate
according to the driving conditions so as to achieve more comfortable and
better shift quality.
7.13 AFS (Adaptive Front-lighting System) Reset
This feature is used to initialize the adaptive headlamp system. According to the
ambient light intensity, the adaptive headlamp system may decide whether to
automatically turn on the headlamps, and timely adjust the headlamp lighting
angle while monitoring the vehicle speed and body posture.
7.14 Sunroof Initialization
This function can set the sunroof lock off, closed when it rains, sliding / tilting
sunroof memory function, temperature threshold outside the car etc.
7.15 Suspension Calibration
1. This function can adjust the height of the body.
2. When replacing the body height sensor in the air suspension system, or
control module or when the vehicle level is incorrect, you need to perform this
function to adjust the body height sensor for level calibration.
