Thinkscan SD4 is a new generation of mid-to-high-end DIY products based on the Android system launched by THINKCAR, which can realize an online upgrade of diagnostic software. Its main functions include not only OBD/EOBD standard protocol diagnosis, but more importantly, it has professional vehicle diagnostic software and maintenance software, which can perform a comprehensive diagnosis of all vehicle electronic control systems. Different series support different systems and functions.
Thinkscan SD4 Supports ABS SRS ECM TCM system diagnose Functions:
Can choose only 3 Reset Function Free, the other reset functions need to subscribe: US$29.95 per reset function 1 year Free.
1. Oil Reset
The lighting of the car maintenance light indicates that the vehicle needs maintenance. Reset the mileage or driving time to zero after the maintenance, so the maintenance light will go out and the system will start a new maintenance cycle.
2. Elec.Throttle Adaption Elec.
Throttle Adaption is to utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state. By doing these, the movement of the throttle (or idle motor)can be more accurately controlled, thus adjusting the intake volume.
3. Steering Angle Reset
To reset the steering angle, first find the relative zero point position for the car to drive in a straight line. Taking this position as a 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.
4. Battery Matching
This function enables you to perform a resetting operation on the monitoring unit of the vehicle battery, in which the original low battery fault information will be cleared and battery matching will be done.
5. ABS Bleeding
When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity. lf 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.
6. Break-pad Reset
lf the brake pad wears the brake pad sense line, the brake pad sense line sends 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.
7. 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 to reduce PMS ignition combustion) to stabilize the filter performance.
8. Gear Learning
The crankshaft position sensor learns crankshaft gear machining tolerance and saves to the computerto more accurately diagnose engine misfires. lf gear learning is not performed for a car equipped withDelphi engine, the MlL turns on after the engine is started. The diagnostic device detects the DTC P1336'gear not learned'. In this case, you must use the diagnostic device to perform gear learning for the car. After gear learning is successful, the MIL turns off. After the engine ECU, crankshaft position sensor, orcrankshaft flywheel is replaced, or the DTC 'gear not learned" is present, gear learning must be performed.
9. IMMO Service
To prevent the car from being used by unauthorized keys, the anti-theft key matching function must be performed so that the immobilizer control system on the car identifies and authorizes remote control keys to normally use the car. When the ignition switch key, ignition switch, combined instrument panel,ECU,BCM, or remote control battery is replaced, anti-theft key matching must be performed
10. Injector Coding
Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder to more accurately control or correct cylinder injection quantity. After the ECU or injector is replaced, the injector code of each cylinder must be confirmed or re-coded so that the cylinder can better identify injectors to accurately control fuel injection.
11. TPMS Reset
After the tire pressure MIL turns on and maintenance is performed, the tire pressure resetting functionmust be performed to reset tire pressure and turn off the tire pressure MIL. Tire pressure resetting mustbe performed after maintenance is performed in the following cases: tire pressure is too low, tire leaks, tirepressure monitoring device is replaced or installed, the tire is replaced, the tire pressure sensor is damaged,andtire is replaced for the car with tire pressure monitoring function.
12. Suspension Matching
This function can adjust the height of the body. When replacing the body height sensor in the airsuspension system, or control module or when the vehicle level is incorrect, you need to perform thisfunction to adjust the body height sensor for level calibration.
13. AFS Reset
This feature is used to initialize the adaptive headlamp system. According to the ambient light intensity, theadaptive headlamp system may decide whether to automatically turn on the headlamps and timely adjustthe headlamp lighting angle while monitoring the vehicle speed and body posture.
14. A/T Learning
This function can complete the gearbox self-learning to improve gear shifting quality. When the gearbox isdisassembled or repaired (after some of the car battery is powered off), it will lead to shifting delay or impactproblem. In this case, this function needs to be done so that the gearbox can automatically compensateaccording to the driving conditions to achieve more comfortable and better shift quality.
15. Sunroof Initialization
This function can set the sunroof lock off, closed it when it rains, slide/tilting the sunroof memory function, temperature threshold outside the car, etc.
16. EGR Adaption
This function is used to learn the EGR (Exhaust Gas Recirculation) valve after it is cleaned or replaced.
17. Odometer Reset
Do reset is to copy, write, or rewrite the value of kilometers in the chip of the odometer by using a car diagnostic computer and data cable, so that the odometer shows the actual mileage. b)Usually when the mileage is not correct due to the damaged vehicle speed sensor or odometer failure, it is necessary to do ODo reset after maintenance.
18. Airbag Reset
This function resets the airbag data to clear the airbag collision fault indicator. When the vehicle collidesand the airbag deploys, the corresponding fault code of the collision data appears, the airbag indicatorlights up, and the fault code cannot be cleared. Since the data inside the airbag computer is disposable,it is required that all new accessories must be replaced, but after performing this function, the data of theairbag computer can be recovered and the fault code can be cleared, the airbag light will go out, and the air bag computer can continue to use.
19. Transport Mode
ln order to reduce power consumption, the following functions may be disabled, including limiting the vehicle speed, not waking up the door opening network, disabling the remote control key, etc. At this time, the transport mode needs to be deactivated to restore the vehicle to normal.
20. A/F Reset
This function is applied to set or learn Air/Fuel ratio parameters.
21. Stop/Start Reset
This function is used to open or close the automatic start-stop function via setting the hidden function in ECU(provided that the vehicle has a hidden function and is supported by hardware).
22. NOx Sensor Reset
NOx sensor is a sensor used to detect the content of nitrogen oxides (NOx) in engine exhaust. lf the NOx fault is re-initialized and the NOx catalytic converter is replaced, it is necessary to reset the catalytic converter learned value stored in the engine ECU.
23. AdBlue Reset (Diesel Engine Exhaust Gas Filter)
After the diesel exhaust treatment fluid (car urea) is replaced or filled up, the urea reset operation is required.
24. Seat Calibration
This function is applied to match the seats with memory functions that are replaced and repaired.
25. Coolant Bleeding
Use this function to activate the electronic water pump before venting the cooling system.
26. Tyre Reset
This function is used to set the size parameters of the modified or replaced tire.
27. Windows Calibration
This feature is designed to perform door window matching to recover ECU initial memory and recover the automatic ascending and descending function of the power window.
Change This function is used to change the system language of the vehicle's central control panel.
