[Anydraj]

Hi all,

Interface correct connect PC.No communication cars.Not working relay and no power PIC16F684, relay etc..
Need dump flash W25x80AV.

[AGK]

1.if there is no power in PIC, check Q4.
2.if there is no +5 V, check LM2674(U5) and diodes D3,D4.

[MOBILTRONIC]

Check,mate,V-mos transistors on other side pcb,one by one.Only one is defect.Cheers!

On your photos, check D1 and may be T3,T4 (hard to see the notation of transistors).
One transistor (2N7002) is connected with 4 pin PIC, the other with 1 pin .

After jerking around with my lexia conecting only with pc but not with car tested all the above methods but nothing . At first i didnt have 5 volts on pic and relays not working i managed to repair that after same thing relays dont working. Started reprograming all the chips one by one everthing ok with the chips. Finaly tried to reprog 25x80 it turned out to be the problem faulty eprom. Got an old broken laptop with bios eprom 25x80 reprogrammed with the file posted here and voala . Works like charm.

After conecting to vehicle lexia stopped working. Came home and stared reprograming all the mcus again.Everything ok except the 25x80 eprom which had memory changed. Reprogramed again with the file posted here and tested on the bench, relays started clicking again everthing ok , removed power suply reconected again same thing stopped working , everything okk except relays dont click. Reprogramed the 25x80 again with seeprog, put software write protection and lifted pin 3 and conected with pin 4 and everthing works like charm tested on three vehicles several times still havent tested CAN VAN vehicle thou.

reflashed software in PIC16F684 only.

how can reflash software in MB90F546? is it possible with Elnec?
How can I check relay's drivers MC1413DG and MC1413BD?

who can me help for free please?
I'm not sure if Elnec can work in ISP mode - this is the best way to reprogram MB90F546. All signals are on the socked in the corner of MB90F546 board.

To admin - remove this message, please

Try using DiagBox with autoupdate of interface firmware. What cars (model/ year of production) are you testing? Are VAN-CAN cars diagnosing correct?

[btr]

Try using DiagBox with autoupdate of interface firmware. What cars (model/ year of production) are you testing? Are VAN-CAN cars diagnosing correct?
VAN-CAN cars diagnosis only k-line all ecus(abs,ecu,airbag...)I do not think that the problem is in the firmware of interface,that do not want to work with CAN line.

[nickowski]

VAN-CAN cars diagnosis only k-line all ecus(abs,ecu,airbag...)I do not think that the problem is in the firmware of interface,that do not want to work with CAN line.
It's nearly right, but VIN is reading from BSI by CAN so at start CAN bus is working well. In VAN-CAN cars not all ECU's are testnig by K-Line (only engine, abs sometime airbag). Others (BSI, radio, automatic gear etc) are on CAN BUS.

Hi !
I have a "minor" probleme using the Lexia3. I can't comunicate with the newer (after 1999) clima ecu of the Xsara/Xantia car. If I watch the signal on an oscope the ECU is respondig to the diag interface but the soft (Lexia3 45) report is "no response from ecu". I tried with other clima ECUs (same number/revision) but no change.

What shoud I try first ? Instal older version of Lexia, reprogram the interface (pic,...)

[odednovo]

I bought a Lexia and it was not detected by software.
I opened the box and saw that the worker which connected the cable connector to the PCB pushed it badly and made a short between the two marked pins (the sixth pins from the top)
I fixed the connector and the pins and now the software detects the cable but when connecting the car I hear the relay bat no communication with the car.
I suspect that the short made a problem but I can not find which components connected to these two pins
Anybody can help?

Hello everyone
I have a cloned China Lexia-3 interface. The cable was working perfectly with Lexia 3.499 (downgrade firmware version 4.2.2). Yesterday I tried to use the cable again, but the software indicates that it is not possible to initialize it (as if does not exist) :dong:.

Windows displays the device as having been installed successfully, the led flashes twice and stays fixed.

From PSA Interface Checker, can't I get the version of the firmware (not let me reflash).

Do I need to reflash PIC16, MB90, and 28W40?
Change RAM?

I would appreciate a little help.

Thanks a lot.

[Dacha]

It may be that the problem is in SRAM.


The same happened to me that I was working with the interface, and left it right next time when I contacted the connector problem that the green indicator is off and the program does not communicate with the interface.
Opened the weld interface and all the components in it again and then started working and now an indication of continuing his work but there is some problem running the software. I have programmed flash, and the PIC processor, but nothing has changed.I will soon have a new SRAM and I'll try and answer.

HELP ME PLEASE

[bubu782001]

Lexia is DEAD. It was connected to the car (unsupervised for about 30 min), and after that, interface was dead, no responding, not recognized by windows (not even "unknown device") and the LED stay OFF.
What should i check first ? Can be a firmware problem or USBN9604-28M controller?

Thank you.

[dany mec]

What can happen with USBN9604-28M interface to not go?

[bubu782001]

I don't know, but USBN9604-28M is the first device used between USB port and the rest of the interface, and since is NOT recognized...at all i suspect this chip as "play dead"

[morfej]

You can't say if USBN9604 is dead or not ... as all the settings for controller is set from Fujitsu MCU... so apperantly if it get power it is not setup from Fujitsu. USBN9604 is not like FTDI which when it get power it is shown in device manager if connected to computer.

First check power supply of Fujitsu and USBN9604.

Hello,

My interface does not connect to pc Unrecognized USB device.
Tried changing usb and sram chips with no luck, reflashed w25x40 but still no problems solved, so I'm trying to flash M90 chip but with no luck.
I've build programmer from a schematics on the forum, but when I try to flash MCU I get

>isp_mb9X /o4 /a /MB90F546GS /b Fuji_MCU.bin /e /c /p /v


InSystem Serial Programmer MB9X. v2.12(win32) (c) S.Pinigin
BIROM Baud :

and sometimes this one

Downloading MB90 m_flash.543 for parameter /MB90F546GS : Ok
Erase : . Ok

Program:

When I power programmer lexia green led blinks and keeps lighting but when i run a programing it turns off.
Should it be so? Or it indicates the MCU is dead?

---- UPDATE ------

I've managed to write MCU, tried to read and compared with original and it's the same.
But still my pc does not recognize a device. Where to look for a problem.
Checked voltage on usb chip 18 pin and there is 3.3V

Fixed my interface replacing faulty 15pin connector

Hello, I've got an xm y4 and a C5 I and the Lexia3 works most of the time. But sometimes, when I have a longer process, like recycling the FAP, it starts the process, finished it. Then get the message that there has been a communication interupt to the car. Could that be a cable, that is not fixed or a cold solder spot ? After that I can go back to menu and try again, but its always the same. Please help.:grey:

When I plug-in USB, LED is green 2-3 sec, flash about 2-3 sec and remain green.


The Firmware is OK, working on another interface and 25Q80 dump is Ok too.

After every USB Plug-in the content of 25W80 is 00 on few rows and FF on the oters rows..

I have a serial version B
And it would come when connected to diagbox 7.xx
earlier connected without problem using lexia Citroen.
I think we need a reflash

Hi Guys i have a problem with my lexia3 i bought one about a year ago couldn't get any communication with cars.I got a firmware upgrade from Mr NLC and no better so i thought the VCI was faulty.I then bought another on Full chips and rev C still the same a friend looked at the board and said he would clean the board.
Now when i plug it in the ignition lights come on and the immobiliser light flashes with no keys in the ignition.If i remove the lexia ,start the car then diagbox and plug in lexia ,diagbox still has no communication with car and wont turn off till i remove the lexia.Can anyone tell me what resistors or transistors or any other thing i can check
Thanks for any help

Hi ,


:joyous:All right, it's OK.:joyous:
I found the problem on this interface (more precisely on the microprocessor MB90F546GS board).


Summary:
The problem: When connecting to the USB port, the card is recognized and detected with USB com board driver. After flash spi flash (Winbond W25Q80B) for changing the serial number and flash MB90F546GS microprocessor with SCARY file for recognition in EVOLUTION driver; the interface is no longer recognized on USB port ????? After re-reading the SPI flash, this one is empty ???


Solution:
Missing +Vcc on the pull-up resistor 3.9 Kohms, inner track probably cut ...
Setting up a wire to bring the +Vcc on the pull-up resistor.

Trouble shooting Description: After changing many components, among other SPI flash, HA86, Micro MB90F546GS ... etc, I have come to think of a concern for missing pull up resistor or a problem on a layer track internal ...
Indeed, the return signal for communication between pin 2 (DO: data output) of the spi flash W25Q80B and pin 28 (P50 / SIN2: Serial data input) of the microprocessor MB90F546GS fact it through two logic circuits: a ACHT86 and HB125; in order to change the logic state and complicate the task of reverse engineering.

I decided to delete the diag and install the PP2000, as for Peugeot 406 hdi comes well.
After a few attempts he there recognized the interface but does not communicate with the other modules, only detected the engine. And since my colleague had complained that he had also given the same problem.

For the diagbox, and pp2000, they are installed on different computers machines.
On what had diagbox even ended up uninstalling diagbox.

Relative to the interface, you say it's a lot of poor quality?
I mentioned that was Chinese.

Hi kelekele,

If I may:Chinese integrate capacitors (or nothing on low cost interface) to the locations that you mentioned but it is not these components are mounted on the original interfaces.
These are TVS diodes suppressors (for protection lines), look my thread here:

http://www.digital-kaos.co.uk/forums/showthread.php/483539-Edit-your-XS-EVOLUTION-interface-to-make-it-equivalent-to-an-original!

But thank you for measure capacitors which many still wonder what value they are!

This components on my photo is capacitors.I remove them from original lexia relay pcb.Without this capacitors not working CAN connection on clone interface .When i remove(and measure) them from original and put them to clone pcb,CAN start working without problems.This is tested sollution and works.

[titoun]

Yes, on your picture but it's a chinese clone PCB.
On this picture : Original interface XS EVO relay PCB (B revision PCB), we can see in location 1,2,3 and 5 same as your picture, there is no capacitors...But "Blue/green" components.

In location 4, it's a capacitor. OK

Are you sure you have removed them from an original PCB?

Hi kelekele,

Sorry but it's not an original XS EVOLUTION interface. For several reasons: comparison with this original

358991
358993

some differences circled in red :

358997

On Microprocessor PCB:
- No TVS suppressor for ESD on each lines of USB 5+/-), chinese replace by capacitors
- No COMMON Mode choke for reduce noise on USB lines, chinese replace by two 0 ohm resistors
- No connector to access microprocessor MB90F546GS for Reflash, chinese replace by none... etc

On Relay PCB:
- Bad white 22 pts connector without holding lugs to be welded on each side
- I suppose (no good photo) bad reference of varistor, good is littlefuse(red) ref P18Z40 marking code
- No TVS suppressor at side of PIC 16F684
- FT relays of Fujitsu mounted by chinese, on original mainly OMRON relays... etc



This your original lexia board is different,not same like Titouns...

Yes, on photo post by morfej,it's PCB revision C of an original XS EVOLUTION interface. But differencies with PCB revision B are minor: resistance 500 ohm (501 marking code) is divided into two resistors of1 Kohm (102 marking code) for a breakdown voltage protection, the two diodes mounted on the two resistors 100kohms (104 marking code) are now on the other side of the PCB ... etc. But since No changes impacting functionality.

Hi
I've just bought a lexia interface and when I plug in windows says "Unknown USB Device". In device managers appears as VID_0000%PID_0000. Tried another USB cable, changed D-SUB port, reflashed both MCU and SPI still nothing.I've checked power supply on MCU,SPI USBN all good. Could be a bad RAM?

Thanks

Sure, when I plug the LED flashed three times and then windows says USB Device not recognized. If I select properties it says "Windows has stopped this device because it has reported problems (Code 43)"

LE: Changed with an old laptop and USB works now, but won't connect to any ECU, also no relay "ticking" in VCI
Any suggestion? Could be FW or a HW problem? Thanks

Hi,

How is your interface recognized in the device manager? With driver: USB com board driver or USB com board Evolution driver?
You use what diagbox software or lexia3 Vxx (alone) or PP2000 Vxx (alone) ?
If your interface is flashed correctly, so may be an hardware problem, post photos of PCB pls !

Hi, I have problems with my new interface. I can't connect to Engine and ESP in any car (406 coupe 2.2HDI and 307 2.0HDI). Other systems seems to be ok, so I don't know if my interface have problems with CAN maybe?

Wich components should I check??

Thanks!

Hi,

Try this :

http://www.digital-kaos.co.uk/forums/showthread.php/468608-PSA-SX-EVO-CAN-communication-problem-!

And if your interface always don't work, check welds of relays, MCP2551, TDK common choke on Relays PCB.
After check welds on HC04, optocouplers 0639 and HC 08 on Microprocessor PCB.
For my part, i will replace all HCPL 0639 optocouplers be HCPL 063N.

Thanks titoun.

My interface doesn't have the CAN resistor, so I'll try your solution.

Hello again.
I changed my RAM chip but the problem remains.
Computer does not respond inclusion of pro usb and LED does not light up.
It can be damaged usb chip?

[titoun]

Hi,

Yes USBN9604 USB controller may be damaged .... but first : try to reflash microprocessor MB90F546GS (with nlc firmware or hardware method)

Regards

[johny2h]

hardware method - with Fujitsu serial Programmer 16LX and FR FLASH MCU ?
thanks

Hi,

Yes of course ! :-)

I measured the voltage of the legs.
All have 5 volts with the exception of 2.
Is this normal?

What transistors have to be:
n-channel or p-channel
T3 (4pin PIC) = 352A4 - p-channel ? (datasheet 352AP)
T5 (1pin PIC) = 352A4 - p-channel ?
T6 = Y2. - p-channel
7002 - n-channel

Thank you in advance for your answer.

-------------------
Replaced 3 transistors (T3, T5, T6) for p-channel. The voltage (PIC) at pin1-5V, pin4-12V.
Relays still do not work.

Help!.

Hello everyone,

I just bought a pp2000 interface, new one "chinese" that's flashed and detected by computer as revolution, it's a rev C.

Installed diagbox 7.02 but cannot communicat with my car, the green light stay on.

My car is 307 1.6 2006

I didn't test it on other cars... if i change the RAM can it work on my 307???!!

Thank you so much

Hi, this is the picture of PCBs.

I did a check with multimetre but there's no power on the second board. so i did check the connection between the two board and there's no power too. "i circle it in RED on picture"

That's mean that the problem come from the first board connected to USB.

Hi,

Relay PCB board take power of 12Vdc OBD plug (on car or on table power supply). And 5Vdc (always on relay pcb) is make by 2674 M5.0. Check this !
On microprocessor PCB board you don't have a good optocoupleur reference (Goods are : HCPL 063N and HCPL 0500), i don't see reference ? and some are replaced by transistors or 0 ohm...

Hi

For the 2674 M5.0. can you tell me how to check it with multim?tre. Must i connect to usb or to obd before cheking??

For optocoupleur there is just two:
9817A-2 and 500 515

Edit:
My car is 307 can.

Usbn9604 chip mounted on the motherboard only supports USB 1.0-1.1?
Bios on the computer is enabled to use USB1?

I bought lexia interface, it connecting with 407 2007, but don't communicate with abs block (with other diagnostic abs is communicating)
And not communite at all with old cars, 206 1999 year, 607 2001 year, with diagbox 7, and pp2000 v25.
For what reason, for missing optocouplers or something else?
Thanks

[Romcik]

Any help?
Why can't connect with oldest cars?
I think for missing 1 optocoupler, 3 from right side?
Pcb have 1 only.

Thanks

Hi,

Yes HCPL 063N instead of 2x1kohms (102marking code) and a strange strap.
But in your place i replace all 0 ohm and transistors by HCPL0500 and HCPL 063N, as in this image:

Hi, I have lexia with low quality board, on the board miss CAN common mode choke filter TDK, there is no place for it. Can I repair this board to work on van and can cars or is better to buy new one. Here is the picture with missing part.

Hi,

The absence of the common mode choke CAN on the relay card will not prevent your interface from functioning, if it does not work it is faulty.
So either you return it to the seller (Chinese I suppose), or you repair it (or have it repaired).

hello my xs evolution is work perfect in can but not communication in van
what is it please?
this relay work but not communication
