DS150 good quality single board required components

[crouchinggerbil]

Goodnight,
I have 1 ds150 interface and I can't diagnose trucks with autocom.
I've had cdp+ since 2017 and probably the quality of the components can't be the best.
Can you tell me which components I should change and where I should buy them

Is it single or double pcb inside?

If it is double then you need to buy single pcb mentioned above.

If it is single then the required components are listed above.

You can get from mouser, farnell, rs-online or other component supplier near you.

Just got new interface with 4.5v relays marked up as 5v.. apart from 1 which is a 3v relay 64ohms.....rest of the relays 140 ohms...why they done that?...buffoons...so make sure you check your interface...not sure the consequences using it with 3v relay; in 2 minds changing for another 4.5v relay.

Pure and simple laziness, it should not matter anyway as voltage is controlled before the relays

If the circuit for 5v 1amp 140mW relay....then adding low volage relay operating at around 5v will stop working eventually. ....short term would probably work but eventually will give up as its under rated for the circuit...not got the schematic tried Google but no good...I guess what you saying its regulated before the relay coil...hard to find the relays in local store...I found a Fujitsu labeled relay which is equivalent..2FC relay

Anyone know why the TJA1050 is there....not doing anything or going anywhere on the board...on the single board with 701 inductor coils..second 701 filter which has got a white smd component in between the 2 coils....tried belling/continuty around the board and nothing...CAN high and CAN low not connected..is this maybe something to do with Trucks and not connected....looks to me the 000 resistors Both CANs connected to the cap

Other with 000 resistors instead of CAN 701...but middle pins connected with pin 8 connected to vire.

mine too, even via not connected on top pin

Thats because the trace goes to other side of the board.

nitin78, you should replace can filters for sure, I also replaced other components to new genuine ones on that vci

There is other difference on the board if you flip the board over. ....you will see 9241A bottom chip nothing connected...China version you get 2 version you get 4.5v relays with 701 inductor....apparently there best....then you get B version which is your version without 701 or 4.5v relays....BUT both version dont have the 1 of the CAN connected....and both version dont have 9241A bottom chip connected.......so basically working on 1 can and 1 9241A....as far I can see...no wonder some module dont seem to communicate...although connection to car OK.

The white marks are where the bad clone are not connected.

They dont go under...as far I checked unless someone can point out where they go..pins 6 and 7 CAN should go to 701 but they dont nothing.....I could take that chip out and it will still work same.

i have replaced the can filter with some original tdk ones. not sure which other component to change but they "look" ok.

i can connect to my qashqai but not much options available like functions.

i wonder if the board just needs a few jumpers to make it work.

which 9241A is it?

Updated with picture left side bad clone right side good clone....

The brown pcb is good quality alright but it is not made any more. The ones from obd2cartool are best one we have tested

thanks do you think it could be modifyed with jumpers or is there more missing elsewhere, might have to buy the one from obd2cartool .

another reviewer on aliexpress put a picture of then canbus ic removed.

looks like no connection to the pads.

thanks. any chance to get higher quality images. might give it a go to modify it.
