Launch X431 V 11 User manual

LAUNCH X431 V 11 Reset Service Function:
1. Oil Reset Service：
⚫If the service lamp is on, you must provide service for the car. After service,
you need to reset the driving mileage or driving time so that the service lamp
turns off and the system enables the new service cycle.
⚫After changing engine oil or electric appliances that monitor oil life, you
needto reset the service lamp
2. Steering Angle Calibrationa
⚫First find the relative zero-point position for the car to drive in straight line.
Taking this position as reference, the ECU can calculate the accurate angle for
left and right steering.
⚫After replacing the steering angle position sensor, replacing steering
mechanical parts (such as steeringgearbox, steering column, end tie rod,
steering knuckle), performing four-wheel alignment, or recovering car body,
you must reset the steering angle
3. Electronic Parking Brake Reseta
⚫If the brake pad wears the brake pad sense line, the brake pad sense
linesends a signal sense line to the on-board computer to replace the brake
pad.
⚫After replacing the brake pad, you must reset the brake pad. Otherwise, the
car alarms.
⚫Reset must be performed in the following cases: The brake pad and brake
pad wear sensor are replaced. The brake pad indicator lamp is on.The brake
pad sensor circuit is short, which is recovered.The servo motor is replaced
4. ABS Bleeding
⚫This function allows you to perform various bi-directional tests to check the
operating conditions of Anti-lock Braking System (ABS)
⚫When the ABS contain air, the ABS bleeding function must be performed to
bleed the brake system to restore ABS brake sensitivity.
⚫If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake
line, or brake fluid is replaced, the ABS bleeding function must be performed
to bleed the ABS
5. Electronic Throttle Position Reset / Learn
This function enables you to initialize the throttle actuators so that the “learned”
values stored on ECU are returned to the default state. Doing so can accurately
regulate throttle (or idle engine) operations to control the amount of air intake.

Throttle matching must be performed in the following cases:
⚫The ECU is replaced, and the ECU does not yet store throttle working features.
⚫The ECU is disconnected from power and the ECU memory is lost.
⚫The throttle assembly is replaced. d) The intake pipe is replaced or removed,
which affects idle speed control by ECU and throttle body.
⚫The throttle is cleaned. Although the idle throttle potentiometer features remain
unchanged, with the same throttle opening, the air inflow has changed and
idle speed control features havechanged.
6. Battery Register/Battery Maintenance
Perform a resetting operation on the monitoring unit of vehicle battery, in which
the original low battery fault information will be cleared, and battery matching
will be done. Battery matching must be performed in the following cases:
⚫Main battery is replaced. Battery matching must be performed to clear
original low battery information and prevent the related control module
from detecting false information. If the related control module detects false
information, it will invalidate some electric auxiliary functions, such as
automatic start & stop function, sunroof without one-key trigger function,
power window without automatic function.
⚫Battery monitoring sensor. Batterymatching is performed to re-match the
control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displaying on the instrument
panel
7. Diesel Particulate Filter (DPF) Regeneration
DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter
through continuous combustion oxidation mode (such as high temperature
heating combustion, fuel additive or catalyst reduce PM ignition combustion) to
stabilize the filter performance.DPF regeneration may be performed in the
following cases:
⚫The exhaust back pressure sensor is replaced.
⚫The PM trap is removed or replaced.
⚫The fuel additive nozzle is removed or replaced.
⚫The catalytic oxidizer is removed or replaced.
⚫The DPF regeneration MIL is on and maintenance is performed.
⚫The DPF regeneration control module is repg)
8. TPMS Tire Pressure Monitoring Sytem Reset
makes tpms senser in displaying sensor ids from the vehicle’s ECU inputting TPM
Ssensor replacement ids and activate tpms sensors
9. IMMO BILIZER
This function can protect your car from being stolen by clearing the lost car key
information and programming newkey into the ECU database. Also known as keys

programming.
10.Injector Coding
Diesel injector code need programming ID and parameters to the ECU for accurate
communication and Injection control system
11)Camshaft Gear Learning
The scan tool monitors certain Camshaft position sensors signals to determine if all
conditions are metto continue with the procedure for Engine running
12)TBA/TPS Throttle Body Alignment
Reset vehicle's throttle position system sensor connect ed to the butterfly spindle
and is primarily used to monitor the throttle position within an innercombustion
engine. Due to its location, the throttle position sensor can effectively observe
where the throttle butterfly valveis positioned
