Astounding Features of the Launch x431 pro3s+ Bi-Directional Scan Tool

The Launch x431 pro3s+ is full of tons of emerging features. This scanner can almost scan the top to bottom of the car, and it is incorporated with too many colossal features that make it one of the most unpredictable elements in the scanning arena. In the next phase, we will discuss the astounding features of this scanning gadget.

Electronic Parking Brake (EPB) Reset

The EPB is used mainly to achieve the optimum locking effect and rejuvenate the braking system performance. If any type of wear and tear occurs on the brake pads and brake pad sense line, then the EPB system generates a humongous sense of emergency that alerts the vehicle’s braking system. The brake pad sense line dispatches a furious signal sense line to the onboard computer to replace the braking pad. After replacing the brake pad, it is necessary to repair the brake pad. If this is not initiated in a proper manner, then all the braking systems may collapse.

Steering Angle Calibration (SAS) module 

If you want to shuffle the steering wheel angle, then you must find out the relative central position of the vehicle, note this point as the landmark, and then start the calculation. The car’s main portion, the  ECU, can evaluate the proper left and right steering angle with no calculation error. Then a replacement of the steering angle position sensor needed to be initiated to figure out where the actual fault was. You must also perform the evaluation of the steering gearbox, steering column, end tie rod, steering knuckle, and so on. In the case of monitoring the four-wheel alignment, you must reset the steering angle. You will find all the diagnosis elements in the single-line Launch x431 pro3s+ scanning model.

ABS Bleeding calculation 

ABS is a mechanism that is architectured to convey and maintain the utmost traction and steering control when the user has initiated extensive braking. If the wheel lock event happens, then the ECU fetches a soft reminder to the appropriate modulator valve to grab, apply or reinvent the brakes as per repercussions. The wheel speed sensors work automatically when the ECU sends a possible signal to this segment. If the ABS computer, ABS pump, controlling cylinder, braking cylinder, braking line, or braking liquid is replaced, the ABS bleeding function acts according to the change. Launch x431 pro3s+ Plus scanning has all the tools to diagnose the full ABS mechanism internally.

TPMS management 

This typical tire pressure monitoring system (TPMS) is specifically intended for automotive use. It can be taken as the landmark spot to initiate a real-world system based on a complex set of Microchip products. The TPM system is responsible for primarily administering the internal temperature and optimum pressure of the tire of the vehicle. There are a variety of mechanisms that approach the system, although this is one of the most comprehensive auto-location systems. The system components are the TPMS, The TPM system of the following major components: Sensor Transmission Device, RF Receiver mechanism, Low-Frequency administering device, control unit, Tire Pressure Vessel, and many more.Launch x431 PRO3S+ Scanner

IMMO function  

The IMMO anti-theft system is a tremendous addition to the Launch x431 pro3s+. There is an adamant immobilizer that disables the starting procedures of a car’s engine, the ignition system of the car, or the fuel supply. Radiofrequency identification is crucial here to agonize in the ignition key and the radio frequency reader in the steering position. The transponder sends a unification signal to the reader when the ignition key is entered in the car punching loophole. If the code is accurate, the computer initiates the supply of the fuel and ignition systems of the car. And if the code is not in the system, the computer detects the fault code, and the vehicle will be powerless to start until the proper key module is inserted in the ignition.

If you want to impede the unauthorized keypunch, you need to perform the anti-theft key-matching function. The immobilizer control system detects and registers the remote control keys to operate the car.

The instrument panel, ECU, switch key, ignition switch, BCM, or remote control battery need to be rechecked, and the anti-theft key matching should find a portable space to assist the ECU.

The battery management system (BMS)

The most prominent technologies for automotive applications are Lithium-Nickel-Cobalt-Aluminum (NCA), Lithium-Nickel-Manganese-Cobalt (NMC), Lithium-Manganese-Spinel (LMO), Lithium-Titanate (LTO), and Lithium-Iron-Phosphate (LFP) and many more. EV or traction batteries differ from the typical automotive battery in internal combustion engines. All automotive battery chemistries require balancing, monitoring, and cooling systems to control the release of energy, prevent thermal runaway, and ensure a reasonably long life span for the cells.

Lithium-Ion batteries have been available for many years for portable devices such as laptops and mobile phones. Also, BMSs for those devices are available from different IC manufacturers and are already mature. The features of the BMS are Battery modeling, Cell balancing, individual cell voltages, pack current and temperature, Control charge and discharge conditions, Thermal management, Estimation, and communication of important battery parameters. Due to the limitations found on commercially available BMSs, it was decided to develop a new BMS module from scratch using available blocks from main IC manufacturers and add the required targets.

Gearbox repairing 

This function is closely related to the gearbox of the car. The gear-shifting quality is pretty much dependent on this system. When you disassemble or repair the gearbox, it will lead to a shift and delay the initiation of the vehicle. The fuel-air ratio is inevitable for shifting the gear. So the diagnosis tool should also include this to synchronize the scanning system properly. launch x431 pro3s reviews

AFS recheck 

This outstanding AFS feature is meant to be the Adaptive Front-lighting System responsible for light distribution at the frontier headlight so that the guy or vehicle next to the car is vigilant about the running vehicle. It is applied to monitor the adaptive headlight system. With the intensity of the ambient light, the adaptive headlight mechanism may administer the automatically turned-on headlamps.

Bi-directional control

Launch x431 pro3s+ consists of another outstanding feature: the Bi-directional control system. This system can go forward and backward at the same time. It is more like the duplex simulator process in the universal bus system or like the modulator and demodulator system where data can flow on both sides at the same time. Bidirectional control is primarily a generic idea that is applied to describe sending and receiving information between one device and another. The design and initiation of the computer control systems are programmed uniquely to execute the entire scanning system.

ECU Full checking 

The ECU is considered the main governing body of the vehicle. If the ECU turns down, then the whole system may experience a collapse over time. The best feature of Launch x431 pro 3 s+ is scanning in a well-maintained pattern that covers almost all aspects of the vehicle system. The ECU commands the overall modules and internal parts to work correctly and in a soaring manner.
