3.30 CODAGE ECU
After performing the encoding function of some systems, the control unit needs to be
reset. Sometimes bad driving habit data can also be eliminated by resetting the ECU.
The ECU reset service can command the ECU to perform self-reset through diagnostic
commands. There are many forms of reset, which are distinguished according to the
sub-function parameters. The ECU may also be hard factory reset by disconnecting the
battery.
3.31 FRM MATCHING
The foot space module is referred to as FRM. It is composed of a circuit module with a
CPU. Its main function is to control the doors, windows, headlights and communication
system of the vehicle. After matching, it is used to clear the short circuit fault of the
light.
Damage to the FRM module can occur when replacing the battery, if the start switch
is not turned off, if the battery terminal is grounded, or other non-professional battery
operations occur. The general result is that the CPU data on the circuit board is lost, and
control of things such as light, doors, and windows fails. If the data is lost, the same set
of data needs to be rewritten to repair it.
3.32 GATEWAY MODULE DATA CALIBRATION
The gateway control unit needs to be calibrated after replacing to repair inconsistencies,
such as VIN.
A "gateway" is designed between the two independent buses of the power system CAN
and the body system CAN to recognize the resource sharing between each CAN and
feed back the information of each data bus back to the instrument panel.
3.33 RAINFALL LIGHT SENSOR
The rain sensor is used to adjust the automatic wiper frequency and the light sensor
adjusts the light intensity of the automatic headlights according to the ambient light
and darkness. This function can adjust the initial parameters.
3.34 TURBOCHARGING MATCHING
Use this function for learning after replacement of the booster system components or
after resetting turbocharger learning value.
The parameters that affect the engine boost mainly include the air flow of the engine,
the boost pressure ratio, the efficiency of the compressor, and the temperature of the
engine exhaust gas. When replacing parts such as the turbine, its initial value must
be reset, and if fine-tuning is required, some settings may be adjusted through this
function.
