Any difference if you change:
#define OBD_PROTOCOL PROTO_KWP2000_FAST

to be instead:
#define OBD_PROTOCOL PROTO_AUTO

Same response as me (ACC check, OBD cross) using the megalogger kit #3 on ISO9141-2 :/

Hopefully there's a solution. I've tried it on a CAN bus '04 mazda, a 2015 CAN Kia, and a ISO9141-2 '02 Subaru

Stanley,

This is my fourth attempt to communicate with you and all my posts seem to be awaiting moderator approval or something. My Kit #3 has me totally stumped mate. I dont have the OBD-11 module connected as you stated. I have a white screen, blank....

I have the latest sketch and libraries of your page. When I go to verify it I get a zillion error messages. I am sorry for being NTS aboiut this but I enjoy learning. The problem is I cannot get to communicate on this forum and Im getting grumpy as a result.

Can you hook me up so my posts actually appear and Im sure some one with a little pity for an old fart way out of his league will come along and help me out. I love what this device can do and see some great opportunities for it with fleet management.

HELP STANLEY!!!!!!!

Blank screen on LCD normally is caused by sketch not properly compiled and uploaded. Can you check this?

So, my car is ISO 15765-4 CAN 29 bit ID, 500K Speed. What can i do to use kit3?

Should be not any problem with a CAN bus car.

You're right, the kit works on both CAN bus cars. It doesn't work on ISO9141-2. I have tried multiple protocol types in the config.h file, but none of them work.

Hello Stanley,

I also get a white, blank screen when I connect the Kit3 to my car (ISO9141-2).

The sketch is complied and uploaded.

I also tried this one to check the display:

Code: Select all

#include <Wire.h>
#include <MultiLCD.h>

LCD_SSD1289 lcd; 

static const PROGMEM uint8_t smile[48 * 48 / 8] = {

void loop()

    lcd.clear();

    lcd.print("Hello, world!");

    lcd.setCursor(0, 1);
    lcd.setFontSize(FONT_SIZE_MEDIUM);
    lcd.print("Hello, world!");

    lcd.setCursor(0, 3);

    lcd.setCursor(0, 4);
    lcd.setFontSize(FONT_SIZE_LARGE);
    lcd.printLong(12345678);

    lcd.setCursor(0, 6);
    lcd.setFontSize(FONT_SIZE_XLARGE);
    lcd.printLong(12345678);

    delay(3000);
}

but without success - I still have a white screen. What am I doing wrong?

I'm a complete beginner, sorry!

What car do you have? The corss at OBD means OBD can't be connected. Have you tried on any other cars?
