During an active test, the tester outputs commands to the ECU
in order todrive the actuators. This test determines the integrity
of the system or parts by reading the engine ECU data, or by
monitoring the operation of the actuators, such as switching a
solenoid, relay, or switch, between two operating states.

EPB Reset
This function has a multitude of usages to maintain the
electronic braking system safely and effectively. The applica-
tions include deactivating and activating the brake control
system, assisting with brake fluid control, opening and closing
brake pads, and setting brakes after disc or pad replacement,
etc
ABS Bleeding
This function allows you to perform various bi-directional tests
to check the operating conditions of Anti-lock Braking System
(ABS).
(1) When the ABS contains air, the ABS bleeding function
must be performed to bleed the brake system to restore ABS
brake sensitivity.
(2) 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.
Throttle Relearn
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.
SAS Reset
To reset the steering angle, 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 steering
gearbox, steering column, end tie rod, steering knuckle),
performing four-wheel alignment, or recovering car body, you
must reset the steering angle.

such as, DTCs, Freeze frame data and manufacturer-specific
enhanced data from the vehicle’s ECM, and reset the I/M
Readiness Monitor Status for all vehicle’s ECM.
This function displays the real time PID data from ECU.
Displayed data includes analog inputs and outputs, digital
inputs and outputs, and system status information broadcast
on the vehicle data stream.
These are codes that were generated during the last drive
cycle, but before the DTC actually sets, two or more consecu-
tive drive cycles are needed. The service is to assist the
service technician after a vehicle repair and after clearing
diagnostic information, by expect or see differences between
makes.
Typically, the stored frame is the last DTC that occurred.
Certain DTCs that have a greater impact on vehicle emission,
have a higher priority. The top prioritized DTC is the one for
which the freeze frame records are retained.
This function is used to check the readiness of the monitoring
system. It is an excellent function to use prior to having a
vehicle inspected for state emissions compliance. Select I/M
readiness to display a sub menu with two choice.
Use this option to view the result of On-Board Monitor tests.
The tests are useful after servicing or after erasing a vehicle’s
control module memory.
The option displays the vehicle identification number (VIN), the
and other information of the test vehicle.
