ii. The ECU is disconnected from power and the ECU memory is lost.
iii. The throttle assembly is replaced.
iv. The intake pipe is replaced or removed, which affects idle speed control by ECU and
throttle body.
v. 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
have changed.
6. Battery Register/BatteryMaintenance
This function enables you to 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:
i. 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 automaticfunction.
ii. Battery monitoring sensor. Battery matching 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 ignitioncombustion) to stabilize the filter performance.
DPF regeneration may be performed in the following cases:
i. The exhaust back pressure sensor is replaced.
ii. The PM trap is removed or replaced.
iii. The fuel additive nozzle is removed or replaced.
iv. The catalytic oxidizer is removed orreplaced.
v. The DPF regeneration MIL is on and maintenance is performed.
vi. The DPF regeneration control module is replaced.
8. TPMS Tire Pressure Monitoring Sytem Reset
makes tpms senser in displaying sensor IDs from the vehicle’s ECU, inputting TPMS sensor
replacement IDs and activate tpms sensors.
9. Anti-Theft Matching (IMMOBILIZER)
This function can protect your car from being stolen by clearing the lost car key information and
programming new key into the ECU database. Also known as keys programming.
10. Injector Coding
i. Diesel injector code need programming ID and parameters to the ECU for accurate
communication and Injection control system.
ii. Program in the new fuel injector numbers after replacement to replace the ones previously
programmed into the ECU.
