Problems with reading with Arduino OBD-II Logger Kit #3

[Gobla]

Hi,

I've received the logger a few days ago but I am still struggling to read out a single car. I've successfully uploaded the firmware and after connecting the kit to the OBD port I get the screen stating the following:

- ACC check
- GPS check (searching)
- OBD error/cross

I've tried to connect with the following cars with either no key, key to acc2 and with a running engine:

- Alfa 156 1.6 2003 (EOBD/OBD2 certified CAN 500 kbit (29 or 11), with and without adapter cable to switch pin 6 to 1 and 14 to 9 pin 7 to 12, the rest was unmodified)
- Fiat Punto 2005 (EOBD/OBD2 certified CAN 29 /500 kbit with and without previous adapter cable)
- Fiat Panda 2003 (with and without previous adapter cable)
- Toyota Prius 1.5 (EOBD/OBD2 certified CAN 11 / 500 kbit no adapter cable).

Any reason why this might not work? I can image some of these cars not working due to strange pinout but I find it odd that none of these work so far.

Kind Regards,
Gobla

Are you using I2C version or UART version adapter?

[Gobla]

I2C

[stanley]

Please check if config.h has correct setup.

My config looks like this:

Code: Select all

Looks all good. Since ACC has tick, the MPU6050 onboard is connected via I2C. Can you try any newer cars?

[Gobla]

I have no newer car available to test this on right now. So I have to get back at this in a few days/weeks.

In the meanwhile is there an option to show the RAW commands that are send and received with the car?

[stanley]

You can modify the code and outputs anything you want to know via Serial.

[Gobla]

I've figured it out!
Using your latest code and some modifications I got it working like a charm.

First of all the protocol was KWP2000Fast so in config.h I used:

Code: Select all

#define OBD_PROTOCOL PROTO_KWP2000_FAST

Futhermore the init is slightly different (obd.cpp)

Code: Select all

const char *initcmd[] = {"ATZ\r","ATE0\r","ATL0\r"};

And I added the following code in obd.cpp after the first "while (available()) read();" in bool COBD::init(byte protocol)

Code: Select all

           write("ATSH");
           write('08110F1');
           write('\r');
           receive(buffer);
           delay(50);
   while (available()) read();

Source on these init codes: http://www.mp3car.com/engine-management ... p2000.html

So this works for the alfa 156, but possible ALL ECU's in Fiat, Alfa, Lancia with the ECU: Bosch M1.5.5

Do you think you could post the OBD.cpp file you used?
