They have the ability to read many different diagnostic protocols (a language used by car diagnostic systems) the tools include protocols such as J1850 VPW, J1850 PWM, ISO15765-4 CAN (11 bit), ISO15765-4 (29 bit), ISO14230-4 KWP, ISO14230-4 KWP (5BPS) & ISO9141.

Remember to let us know which tool your enquiring about, and your vehicle spec (make, model, petrol/diesel, model year)ĭiagnostic code reader can come in many forms, and can be called many things such as OBD2 scanner, OBD2 code reader, EOBD code reader or scanner, Multi System scan tool plus more. If you would like clarification on this please email us. You can buy the tool online and delivery is generally 1-2 working days. It will work on engine, ABS, SRS airbag, gearbox systems & more. It all depends if you want an engine scanner code reader, or a kit/tool that will diagnose other systems like ABS, SRS airbags, transmission etc.įor the Mercedes C Class W203 the best tool is the iCarsoft i980 Multi System Scan Tool because it will allow you to read/diagnose diagnostic trouble/warning codes & then reset them, which will turn off the engine warning light. However, the IC Displays response time is appaling, resulting in somtimes a slushy text animation.The best diagnostic tool for a Mercedes C Class W203 is shown below. This means that if the track name is more than 8 characters, the Arduino will shift the string by 1 every 150MS, resulting in the text scrolling across the screen to display a longer message.

#MERCEDES W203 RADIO DIAGNOSIS HOW TO#

Project LimitationsĬurrently, I have only worked out how to display 1 line of maximum 8 characters on the IC Display. The Solid green wire is CanH+, and the green wire with a white stripe is CanL. Connected to the instrument are 2 green wires. Instead, I ran wires to the back of the Instrument cluster. I could not find a connector like for Bus B. Connection to Can CĬanbus C is a little more difficult.

#MERCEDES W203 RADIO DIAGNOSIS DRIVERS#

This is a hub (with multiple wires coming out of it) located on the panel below the drivers steering wheel. I am using the X30/7 connector to connect to Canbus B. If you end up using 2 modules with 16Mhz clocks, please change the following line in IC_CUSTOM_TEXT/canbuscomm.cpp:įailing to do so may result in some absolutely wild behaviour with the rest of the car! Connection to Can B (I found out that Can B is NOT compatible with the 8Mhz clock due to its odd bitrate of 83.3Kbps). 1 with a 8Mhz Clock thats connected to CAN C, and 1 with a 16Mhz clock that is connected to Can B. (Used to analyze can frames and work out functions of frames)Ĭurrently, I have 2 MCP2515 modules.

Controls enabled via the android application OBD-2 J1850 PWM, J1850 VPW serial ELM327 cable. You can buy the tool online and delivery is. The arduino will then send can frames to the IC Cluster to display the current track playing. For the Mercedes C Class W203 the best tool is the iCarsoft i980 Multi System Scan Tool because it will allow you to read/diagnose diagnostic trouble/warning codes & then reset them, which will turn off the engine warning light. The phone also then tells the Arduino via bluetooth what track is playing. contact K-line immobilizer is on-Sprinter (EWS)and K-line engine block and common PC on MB trucks (Actros, Atego) Contact the tach signal (RPM Signal) monitor engine speed. the power output of the thirtieth circuit. This now serves to give 'hands free music control' to the car, the steering wheel button presses in the AUX Page are now relayed to the phone in order to change tracks. The Pinout of the diagnostic connector Mercedes sprinter 14 pin: ground (-) 31 circuit. The arduino now requires a HC-06 bluetooth module, which then connects to the android application running on an android device. So far, the project has grown well out of proportion and has ended up being a way to modernise the W203 slightly. If you have an android head unit in your car, feel free to checkout a much more feature rich version of this that runs on the headunit here DEMO VIDEOSĬan be accessed via this link Project status If you want to fix things, feel free to submit pull requests to this repository This project is now no longer my primary project for the car

Mercedes canbus project for older W203/W209/W211 carsĪ proof of concept application using an Arduino and Android phone to add extra features to these older Mercedes cars by tapping into their systems via canbus.
