1. New MB SD Connect Compact 4 Star Diagnosis support wireless diagnose;
2. New MB SD Connect Compact 4 Star Diagnosis not only support K line diagnose and CAN BUS,but also UDS diagnose protocol. Because old MB STAR C4 main board do not have UDS chip, so old MB STAR C4 can not support it;
3. Multiplexer now use Lan cable to connect
4. Connector adopt Military quick swap technology, it can support 10,000 times pull plug, more stable;
5. All core accosseries adopt original new packing chip, and 24hours test, guarantee the quality of the products;

a cheaper Lexia 3 Citroen Peugeot diagnostic tool for only 59usd and there are missing some chip, compared to the original one.
Original Lexia 3
Communicated with the vendor, they say the cheap Lexia 3 is designed with this kind of board as what i got.
On original interface “those caps” are resitors (473) 47k – R5 and R6. Optocouplers seems to be HCPL-063N-000E and HCPL-0500-000E. Also the filter from USB input is ACM2012D-900-2P (TDK) – most of clones have not this USB filter (2 resistors of 0 ohms are used).
On relay pcb the round red component is a varistor and original is V18ZA40P (in most clones is blue and have not the same specifications as the red one).
On relay pcb there is another optocoupler ZJYS51R5-2PT-01 (TDK) on the edge area near relays used for VAN BUS.
Some pictures from an original XS EVOLUTION PCB revision C.
He tells me, there mainly are two kinds of Chinese Lexia3 from different factories. One cheaper but lack some chips, the other with full chips of high quality.
The good Lexia 3 should come with PCBs as follows:
It’s item :

And it’s very kind of the vendor that he tells me, even if the PCB is designed as above, there are some different similar clones, not all HQ.
This is the comparison he shows me:
The left: good ; the right: bad
Big thanks to fobdii.com, with lots of info to help me. Finally, i adapted his advice and decided to exchange the cheap Lexia 3 for a high-quality Lexia 3 with a bit more money. It works like a charm now.

Introduction
The check engine light on a Toyota is an indicator that one of the sensors or systems operated or monitored by the computer is malfunctioning.OBDSTAR X300M The computer manages the engine functions and emission controls as well as several other systems. All present day vehicles have the same type of regulatory system employed to operate the function of the drive train.
History
Since 1973 when the auto manufactures first started to employ emission controls on vehicles, computers, still in their infancy, came on the scene. Their initial duties were to monitor the exhaust emissions and make corrections in the timing and the carburetor mixture to control the emissions. A good understanding of the primary function and control the computer has on the impact of the performance of the vehicle serves to lend predictability to the issue. Computers are common place and becoming more and more advanced with increasing responsibilities in the operation of the vehicle.
Functions
The Toyota computer not only operates as an engine management center, but it controls the emissions, the security system, the air conditioning, the suspension, the new Trac systems, the transmission functions and more. It does not however, have anything to do with the internal components of the Toyota engine. The Toyota check engine light does not tell the operator if the engine is low on oil or of a particular malfunction due to wear.
The Toyota has a computer called an Engine Control Management (ECM) computer that controls engine management.UCANDAS VDM2 There is a Automated Braking System (ABS) computer that operates the function of the brakes, a Body Ride Control that operates a multitude of accessory options such as power windows, locks, seats and so on. There is an air conditioning computer for the use of dual air conditioning, a transmission computer, and some that operate in conjunction with the main ECM computer to control the suspension.
Diagnosing
Purchase a computer OBS scanner from a parts store. The OBS scanner is a requirement for diagnosis. It is relatively inexpensive but a necessity. Computers store malfunctions in memory and illuminate the check engine light on the dash. The computer will relinquish these codes in the form of a series of numbers similar to a bar code. To retrieve and understand these codes, you need a scanner. The scanner will come with a code sheet to correspond with the codes presented.
Attach the code scanner to the OBS connector under the driver's side dash. Turn the ignition key on until the lights illuminate on the dash. Do not start the car. The scanner at this time will be displaying read codes. Push the button to read and the scanner will begin to interrogate the computer. It only takes a few seconds and the scanner will respond with a code or codes if more than one. Write these codes down, such as P1425 and look up the codes on the sheet provided for a definition.
Just because the computer generated a code for the oxygen sensor (oxygen sensor malfunction), does not necessarily mean that it is bad and should be replaced. The oxygen sensor measures the amount of oxygen in the exhaust system by producing a very small voltage that the computer sees as an indication as to the fuel mixture being to rich or lean. A multitude of things can cause the oxygen sensor to indicate the wrong mixture.XTOOL HD900 For example a bad spark plug, wire, air leak in the manifold, bad thermostat or bad gas. If the car is running well enough and you see that this code came up, know that no disaster is imminent and continue to drive until it can be repaired or you can check it out yourself. To properly diagnose a code, even with a computer, it helps to read the manual so that you know what each sensor does and what else on the vehicle may cause that sensor to generate a code.
