Re: New implementation of protocol

Hi, After a new try with the new librarie on my father's Opel Insignia (2009), the adapter work quite well with a CANBus protocol (obviously) but doesn't work on a Mini Cooper S (2010) even if I set manually the protocol. I don't know why... I did not have the time to try the new librarie with my ol...

Re: New implementation of protocol

Yes, unsuccessfully, but I remember the device does not work with 2 other cars : Insignia 2009 and Cooper S 2010, auto or manual protocol.
A cheap OBD reader can connect with both and display live data.

I think there is something wrong with my code (or with the adapter, I don't know)

Re: New implementation of protocol

It's not very easy to find something useful, all the documents I've found are in english (not my native language) and there is no custom init sequence for the Opel specific protocol. I've tried to ask to Opel but they replied to me that the protocol is their property (of course). I only know my car ...

Re: New implementation of protocol

Hi, The problem with my car is that when the car was made, the ISO 9141 was not under an offical legislation for all manufacturers. So maybe Opel has made a custom implementation of the ISO (like modifiying the handshake or init sequence). For example, a common and cheap OBD Reader (which is logical...

New implementation of protocol

Hi Stanley,

I have an old car (Opel Vectra B 1998) which is possibly in ISO 9141 and I bought the I2C Adapter for Arduino. Is there a way to implement this protocol ?
If yes, how can I do it ?
To illustrate, how did you implement the other protocols ?

Thanks you,

Re: I2C doesn't work, 3 differents cars

I tried on a car which is KWP2000 certified (work with another scantool and it says that the protocol is KWP2000) I think KWP2000 protocol used by Opel is a bit different so I need to specify a custom init sequence... I still look for a solution and I will return if I find a good way to run the adap...

No PID return

Hi, I have a 1998 Opel Vectra B who have a K-Line, and I recently received the OBD2 I2C Adapter. When I try the "rpm_led_i2c" sketch, obd.init() seems to be OK (I added some Serial.print) but when the Arduino reach obd.read(PID_RPM, value), it's return some weird and wrong values (an old v...

I2C doesn't work, 3 differents cars

Hi Stanley, Sorry for my bad english. I received the OBD2 Adapter Model B yesterday. I tried to connect the adapter to my car (Opel Vectra B from 1998) with "rpm_led_i2c" sketch. Sadly, the led doesn't turn on at 2000 RPM (I lowered to 2000). I tried to explicitly specifiy the communicatio...
