Step 2. Select a service to test and press ENTER key to start.



In next part, all maintenance functions will be explained respectively, including their main concept, applicable range on the vehicles and targeted test options, etc.


1.Electronic Parking Brake — Already tests OK

EPB Service menu allows you to perform the service and maintenance of brake systems, including deactivation and activation of the brake control system, bleeding brake fluid, opening and closing brake pads, and setting brakes after disc or pad replacement, on multiple brands of vehicles where electronic brake systems are fitted.

Some tests display a command to the operator. For example, if “Pressing Brake Pedal” displays, the operator has to press and hold the brake pedal and then continue. Actual tests vary by vehicle manufacturer, year, make.


Typical special test options include:

(1).Deactivate/Activate SBC/EPB systems – allows to deactivate brakes for further service or maintenance work on brake systems or activate brakes when service or maintenance work on brake systems are completed.

(2).Adaptation on Audi A8 – allows to set new pad thickness of rear brakes calipers after changing brake discs & pads on Audi A8 models.

(3).Replace hydraulic brake systems fluid/bleed brake system on Mercedes SBC vehicles – allows to change brake fluid/bleed brake system.

(4).Perform service reset and service position on BMW EPB vehicles – allows to do the CBS reset and CBS correction for front brake and rear brake.

(5).Perform activation/service work on Volvo PBM vehicles – allows to perform installation check, applying parking brake, releasing parking brake, activating service mode and exiting service


(6).Reset memory on Toyota EPB vehicles – allows to clear the learned memory of the EPB ECU.

(7).Perform brake cable replacement and electric parking brake replacement – allows to fit in or remove the brake cable safely, adjust brake cable’s tension and calibrate the electric parking brake replacement.

(8).Save and write clutch pedal programming on Renault EPB vehicles – allows to save clutch pedal programming on Renault vehicles fitted with manual gearbox. After this command is activated, the tool allows to “flash” the electric parking brake unit with the saved clutch data.

(9).Perform control function and reset function on Opel EPB vehicles – allows to apply/release park brake cable service, provide park brake cable service replacement procedures and calibrate the parking brake systems after brake service.

(10).Sensor calibration on Honda EPB vehicles – allows to program the current output value of each sensor into the electric parking brake unit.

(11).Provides parking brake unjam procedure and perform longitudinal accelerometer calibration on Land Rover EPB vehicles – allows to drive the electronic park brake so it is unjamed in the releasing direction and then drive it into mounting position or the latching position; also allows to perform longitudinal accelerometer calibration.


2.Battery Replacement (BRT) — Already tests OK

BRT menu lets you to validate new battery, clear faults from the dashboard and display current battery details of the vehicle such as Audi, BMW, Citroen, Peugeot, Seat, Skoda, Volvo, VW and Ford.


(1). Replace the old battery with the new one. Ensure the key is not in the ignition.

(2). Connect the scanner to the vehicle’s 16 pin Data Link Connector (DLC) with the diagnostic cable.

(3). Boost the device and select BRT; it will display all the vehicle makes available. Choose your vehicle make and follow the scanner instruction to start.


3.Oil Service Reset — Already tests OK

Oil Light Reset menu allows you to reset the service lamps on the instrument cluster. The Service Indicator System is designed to alert the driver when the vehicle is due for a service. Oil service reset methods are determined by the vehicle being tested.

(1).Oil Reset With One Button – applicable to GM models only. It offers quick and simple oil service reset with the click of one button.

(2).Manual Reset – almost all Asian vehicles and most American and European vehicles have mechanical oil service indicator reset. The service tool does not have to communicate with the vehicle being tested, but guides you to complete the service manually by providing step-by-step on-screen instructions. When Manual Reset is selected and the vehicle being tested identified, a procedure opens on the screen. Scroll with arrow keys to read the entire procedure and performing the necessary steps as directed by the on-screen instructions. The exact order of the test operation steps may vary depending on the test vehicle. Be sure to follow all on-screen instructions. The manual reset procedure can be interrupted and aborted if the ignition key position is changed.

(3).Auto Reset – Auto Reset is a bi-directional communication procedure directed by the service tool. The service tool displays guides for you through the process. A number of instructions that require a response to continue display, including an option to clear any stored codes once the interval has been reset. Follow the on-screen instructions.


4.Diesel Particulate Filter (DPF) Regeneration — Already tests OK

DPF Regeneration menu lets you perform the DPF cleaning to clear the blockage through continuous burning of the particulates captured in the DPF filter. When a DPF regeneration cycle is completed, the DPF light automatically goes off.


5.Throttle Body Alignment (TPS/TBA) — Already tests OK

It’s very common to see a customer pull into the shop with a Volkswagen or Audi that just will not idle correctly. One of the possible causes is that the throttle position is not known. When the motion range is not known, the ECU simply has no idea where to set the throttle. The ECU must know the full range of motion of the throttle in order for it to properly control the engine. Using the throttle position sensors in the throttle body, the ECU learns the full open and full closed positions through various states (idle, part throttle, WOT) known as a Throttle Body Alignment (TBA).


6.Steering Angle Sensor (SAS) Calibration — Already tests OK

SAS Calibration menu let you perform calibration of the Steering Angle Sensor, which permanently stores the current steering wheel position as straight-ahead in the sensor EEPROM. On successful calibration of the sensor, its fault memory is automatically cleared.


7.Continuous Variable Transmission (CVT) — Already tests OK

This function is used to reset the compensation code and initialize the ECT after a solenoid valve or valve body assembly has been replaced.


8.Gear Learning — Already tests OK

The crankshaft position sensor learns crankshaft tooth machining tolerance and save to the computer to more accurately diagnose engine misfires. If tooth learning is not performed for a car equipped with Delphi engine, the MIL turns on after the engine is started. The diagnostic device detects the DTC P 1336 ‘tooth not learned’. In this case, you must the diagnostic device to perform tooth learning for the car. After tooth learning is successful, the MIL turns off.

After the engine ECU, crankshaft position sensor, or crankshaft flywheel is replaced, or the DTC ‘tooth not learned’ is present, tooth learning must be performed.


9.Tire Pressure Monitoring System Programming — Already tests OK

TPMS Service menu allows you to check the tire sensor IDs from the vehicle ECU and to perform TPMS programming and reset after tires and/or TPM sensors are replaced and/or tires are rotated.


10.Odometer — Might test OK, but not experience practically yet

This function allows you to revise the date of odometer and write the original date into new odometer.


11.Injector Coding — Might test OK, but not experience practically yet

Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder so as to more accurately control or correct cylinder injection quantity. After the ECU or injector is replaced, injector code of each cylinder must be confirmed or re-coded so that the cylinder can better identify injectors to accurately control fuel injection
