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

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?

I2C

Please check if config.h has correct setup.

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

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?

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

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.htmlSo 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?
