I need "ostrosiowaty"s file.
I would really appreciate any help!
Thank you for your time!
Best regards!

Hello! I have a KIA Sportage 2008 2.0 CRDI Bosch EDC16C39. Some time ago a code arrived, P0489 (EGR low voltage) which triggers limp mode. I deleted the fault path code for this P code, checkengine is off and also zerod out all 2 of the EGR hysteresis maps and the car is still in limp mode. I appreciate any help. Thank you!

I'm looking for advice. This is more or less a continuation of my previous post:

https://www.reddit.com/r/CarHacking/comments/1ep2rwv/can_is_silent_esp32_via_obd2_port/

I'm doing some custom ECU data handling and for this purpose I need a performant way of accessing data from the engine. I made a PoC using the OBD2 port but this won't do in any serious case since it's limited by its protocol to 1 message per ~200ms.

Therefore I want to hook into the CAN somewhere in the car and sniff the frames. Unfortunately, I'm not a mechanic nor an electrician so reading the schematics doesn't give me the best idea how to do it.

You can find schematics here (SWIFT RS413): https://jdmfsm.info/Auto/Japan/Suzuki/Swift/2004-2007%20Service%20Manual/

From what I understood from the manual there's no easily accessible place where I could hook into the CAN. I analyzed some subsystems which have the access to the CAN and I think the reasonable shot there would be accessing it right before the BCM (Body electrical Control Module) unit which actually handles OBD2 communication. All the sweet data should be there. Still, I don't know if it's easily accessible at all.

I have no idea however how safe it is for the car, even if I'd use a CAN shield etc. My car isn't worth a lot but I'm kinda attached to it and don't want to fry something etc.

Can anyone with experience with these matters hint me towards the best approach here? Maybe I missed something obvious in the diagrams or maybe there's some pretty generic, easy way to hook into any car's CAN bus?

Greetings. I have a 2013 XJ Portfolio without massage seats. I've purchased two front seats from a junked 2014 XJ with massage seats. The seats have been installed in my vehicle with the seat modules from the donor vehicle. All of the manual seat controls work as expected i.e. seat movements forward and back, side bolsters, memory function, headrest, heat and cool etc.

I am having trouble getting my vehicle to recognize the newly installed massage seats. I cannot get the massage option to be displayed on the nav screen. I've successfully modified the CCF file parameter "front seat massage" to fitted. No massage option. I suspect that I have to download the software files for the seat modules from the donor vehicle. I have the software files for the driver and passenger seat. However, I cannot get my vehicle to accept the .vbf files to configure the seat modules. I've tried renaming the new software files with same file names as the original files. No success. This results in a file error "Error code A1E = request out of range error". See picture below. I've tried modifying the contents of the vbf files. That resulted in a checksum error during the download. SDD seems to detect any files that are not associated with originally fitted modules.

Does anyone know of any other creative methods to download software files for modules that aren't originally fitted to a vehicle? Any other ideas on getting that massage option to display on the nav screen? Thanks.

I bought a used vn1611 for a good price. Now I need license, does somebody know if I can find old version Canalyzer license (maybe some companies need no more, because they’re using a newer version?) For me canalyzer pro 9 is ok for example (I need CAPL)

If a person was to hack a car what abilities do they have? What all are they able to do to said car?

How can you find out if your car has been hacked?

First off, I'm not sure if this is the right flair, apologies in advance.

Anyway, I own a 2018 Chevrolet Silverado 1500 LTZ and want to tinker with the ECM and BCM to change how my truck works.

I'm not looking to do anything crazy, to start. It's just basic stuff so that I can learn. I've heard about FORScan for the Ford truck market and would like something similar for my Chevy. I know GM dealers have access to programming tools, and unfortunately I am not buddie-buddie with a mechanic that would let me "borrow" a programmer.

For starters, I just want to enable the DRLs when the headlights are on. Add the factory ITBC, maybe even add push-button ignition using the FOB off a 2018/earlier Tahoe/Suburban. Things that the were introduced on the T1XX platform and were tested on K2XX but not added to Silverado. Down the line once I am more comfortable with GMLAN and the other communication protocols on my truck I may want to develop my own head unit that integrates with the various modules on the truck. It would run linux or even AAOS, but thats way down the line.

The last time I went down this rabbit hole I was looking into a Tech2Win device that would let me do the sort of things I want, however, I got sketched out when I needed to acquire the hardware and software from unknown and poorly translated Chinese sites (not to mention that Tech2 is for older trucks and GDS2 documentation stops at MY2013). From that same preliminary research, from what I can tell, the HMI, ECM, and BCM are all MFG'D by BOSCH, thus I would think a tool from BOSCH would work. I can not find such a creature.

I see on fourms that the above is all dirt simple for Ford owners and good for them, GM guys just have to eat it I guess. I also only seem to find these things on Diesel fourms or from Diesel tuners. I guess that community does not want people who cant shell out $100k or more on a truck so have to settle on the gasser 1/2 ton trucks. I digress.

Do designers select the slightly messier intel format because it makes the signals less obvious to snoopers, or are they just trying to be annoying like people who pronounce gif jif?

It messes with what little sense of esthetics I have to see the message layout on frames from the Hyundai and Benz products I've been working on lately, especially when its a mid-length signal like 10-12bits.

First off apologies if I am using the wrong flair I did not know which one to put it under.

Recently I bought a 2013 holden cruze, everything in the car works fine except the dashboard was not showing the kms of the car, after some investigation with a scan tool, I found out that the cluster had a different vin programmed to it compared to the rest of the car, I was also getting an immobaliser fault code from the cluster. This leads me to believe that the previous owner had replaced the cluster without programming it. I bought this ch341a eeprom programmer and then followed instructions from this video on how to install the right drivers and software. When I tried reading the 24c16 eeprom chip the software only showed ff everywhere which according to my research means there is something wrong, I tried unplugging and replugging, clearning the terminals on the chip and connector and flipping the connector to no avail. The only thing I havent tried is desoldering the chip which I am leaving as a last ditch efffort.

one thing I noticed is that on my programmer's chip it says ch341b instead of ch341a which is odd because everywhere else on the programmer it says ch341a.

any help in resolving my issue would be greatly appreciated.>! !<

I am using an OBDLink SX to read sensor data from my car OBD2 port. I am using python to send requests for non-standard PIDs and receiving the correct responses, however the issue I have is the responses seem to be very slow. I would like to log responses at a decent frequency so I would like to understand why it is so slow and if there is any way to speed it up.

Below are the details of my setup, the code I am using to monitor the time for the response to come in and a typical example for one of the requests I am sending.

Details:

• Car: 2019 Hyundai Ioniq Electric
• Protocol: ISO 15765-4 (11-bit, 500kbps)
• OBD reader: OBDLink SX
• Computer: Windows 11 using Python serial library

Code:
The code below is used to send an OBD request then use a loop to check the length of the response until the complete response is received. Each time additional bytes are received it prints the elapsed time and current number of characters received

serial_conn.write(f"AT SH 7E2\r".encode())    # Set header
serial_conn.write(f"21 01\r".encode())        # Send mode and PID

start_time = time.time()                      # start timer
current_buffer = serial_conn.in_waiting       # check length of response in buffer

# check length of response in buffer until complete response is received
while serial_conn.in_waiting < 82 :

    # if response length changes, print elapsed time and current response length
    if current_buffer != serial_conn.in_waiting :

        print(f"{time.time() - start_time}- Buffer size: {serial_conn.in_waiting}")
        current_buffer = serial_conn.in_waiting

# print total time for response to be received in buffer
print(f"Response time: {time.time() - start_time}")  

Typical response:
"7EA 10 16 61 01 FF E0 00 00
7EA 21 09 21 12 40 06 3B 03
7EA 22 00 00 00 00 B7 77 34
7EA 23 07 20 00 00 00 00 00

>"

Code Output:

0.013462066650390625- Buffer size: 20
0.02947258949279785- Buffer size: 60
0.045500993728637695- Buffer size: 80
0.07746386528015137- Buffer size: 82
Response time: 0.07891416549682617

It can be seen that the request I am sending is returning 4 frames. It seems there is ~0.015s between each time frames are received. Initially only frame 1 is received, then frame 2 and 3 are received, finally frame 4 is received. Then it takes another ~0.03s for the end-of-message characters to be received.
If I understand correctly, this is the time it takes for the messages to be sent from the car to the OBD reader. The communication would be at 500kbps
The messages would then have to be sent from the OBDLink to the computer, which would have a baud rate of 115kbps and would further slow data retrieval.

Questions:

1. Is it normal for the OBDLink SX to be this slow?
2. Why is there such a long delay for receiving the end of message character?
3. Could the Python serial library or its configuration be a bottleneck?
4. Would a different OBD adapter (e.g., USB2CAN) provide better performance?
5. Is there anything I am missing that could be causing these slow responses?

I am new to this so any help would be greatly appreciated.

Got this circuit off GitHub. K Line is a 12V signal. Does this look correct? Because unless TX is low (not UART idle state) wouldn’t K Line to RX always read high?

Out of curiosity, do the frames that the ECU transmits that contain the actual unsegmented periodic data have standardized CAN IDs or is this something manufacturer specific?

Put together obd/canbus system containing cluster, bcm, ecu, 8.4 infotainment, center stack, all dodge parts. What I want to know is...what serial number should I use on this setup? I think I should use the bcm ser# across all the units, but thought I'd ask first. And which program should I use to change serial numbers...windows-linux ?? I'm able to connect to all the units with demo of Alfaobd. Now sure if I can use paid Alfaobd for all ser#'s. This is all for me to learn more about the Canbus ID's ,turn parts on/off, figure out errors when something on the canbus goes wrong. Was able to un-loop 8.4 uconnect with linux. So I hope someone with more understanding can help. Thanks.

Hi all, I did the unfortunate thing of going into my diagnostic menu and "initialize system" This basically bricked my audio unit in my Nissan Fuga Y51 with Bose. I now cannot change the ac in the infotainment system. I heard online that the best fix was to get consult 3+ software and module which works with it. Thinking this would be cheaper the dealer option. anyone out there with any suggestions? Thanks

Hi friends, I Want to know if European cars respond to different obd pid's, I have done tests in a VW and responser were not the usual with other cars, different hex size response, variations, etc. Anyone knows if they use obd pids different than this:

Thank you!!

I am an Turo All star host, been using bouncie obd GPS tracker to monitor my cars.

Recently Turo added a new rating category requirement for Maintenance. Myself as well as all host been affected with low rating due to common check engine lights and error.

In all my cars, I have added an Android CarPlay box with dedicated 4g sim.

I was thinking of adding an obd2 splitter.

One for Bouncie and another for obd2 Bluetooth adapters with bidirectional coding. This way if there is any check engine lights or error code I can remote into Android car play box and access obd apps like thinkcar or obdeleven and clear out the code so guest won’t freak out and give me a bad rating.

Bouncie does provide some diagnostic, not too in depth, but does provide realtime gps tracking, speed, and if car has been in a crash. But it doesn’t clear code.

hello guys could not find any other place to write this post😅

I own launch crp919e BT diagnostic tool. Everything is good tool works perfectly. Btw studying work with Car Diagnostics. Today I was trying to change language on Mercedes Benz w212 2014 2.2cdi Found the module in launch changed language but as soon as write coding and leave the module language immediately switched to Deutsch. Any ideas on how to solve this problem?

Hi I have a 2024 Volvo xc40 and I'm not happy with the Google infotainment system. How can I completely erase it and upload my own custom OS to my infotainment system.

Has anyone tried the Webasto Airtop 3500 ST for the MB Actros, or does anyone have information about it? I want to connect it for a bench test and control the heater using the CAN bus protocol. I understand that it supports both W-bus and CAN bus communication capabilities.

I have a CAN bus logger and have been searching for the wiring diagram for this heater. I’ve identified the CAN L and CAN H wires and connected them to my CAN logger while it was still in the truck, but I’m not receiving any messages. I’ve also tried both 250 kb/s and 500 kb/s settings.

Do you have any suggestions for the proper connection configuration?

Hi, Im using Korlan and trying to see the traffic on my can bus but I don't see anything, except those I generate myself with can send. Anyone knows if Honda Odyssey has a security gateway, a firewall or some kind of filtering that do not allow me see the traffic? Thanks

In theory if you were to take a bare block (let’s say a ford 2.3 lima) and put GM sensors on it, converted the distributor to a cam sensor and found a solution for crank signal - would it be able to run the engine?

I figured this group might be interested was it covers multiple disciplines

Could someone download the file for me. I became a father a month ago, unfortunately I don't have the money to register at the moment.
