4.1 What are OBD2 PIDs?

OBD2 PIDs are standardized codes that allow you to request specific pieces of information from the vehicle’s computer. Each PID corresponds to a particular parameter, such as engine RPM, vehicle speed, coolant temperature, and more.

4.2 Common OBD2 PIDs and Their Meanings

Here are some of the most common OBD2 PIDs and their meanings:

PID	Description	Units
0x0C	Engine RPM	RPM
0x0D	Vehicle Speed	km/h
0x05	Coolant Temperature	°C
0x0F	Intake Air Temperature	°C
0x10	Mass Air Flow (MAF) Rate	g/s
0x11	Throttle Position	%
0x04	Calculated Engine Load Value	%
0x2F	Fuel Tank Level Input	%

4.3 How to Request and Interpret Data from PIDs

To request data from a PID, you send a request code to the vehicle’s ECU. The ECU then responds with the requested data, which you need to interpret based on the PID’s specifications.

Here’s an example of how to request and interpret engine RPM (PID 0x0C) using Arduino:

#include <OBD2.h>

OBD2 obd;

void setup() {
  Serial.begin(115200);
  while (!Serial);

  if (obd.begin()) {
    Serial.println("OBD2 connection successful");
  } else {
    Serial.println("Failed to connect to OBD2");
  }
}

void loop() {
  float rpm = obd.readPID(PID_RPM);
  if (rpm > 0) {
    Serial.print("RPM: ");
    Serial.println(rpm);
  } else {
    Serial.println("Failed to read RPM");
  }
  delay(1000);
}

In this code, obd.readPID(PID_RPM) sends the request for engine RPM and returns the value. The value is then printed to the Serial Monitor.

• B (Body): Relates to body components such as airbags, power windows, and central locking.
• C (Chassis): Relates to chassis components such as ABS and traction control.
• U (Network): Relates to the vehicle’s communication network.

5.3 Reading DTCs with Arduino Due

To read DTCs with Arduino Due, you can use the OBD2 library. Here’s an example:

#include <OBD2.h>

OBD2 obd;

void setup() {
  Serial.begin(115200);
  while (!Serial);

  if (obd.begin()) {
    Serial.println("OBD2 connection successful");
  } else {
    Serial.println("Failed to connect to OBD2");
  }
}

void loop() {
  if (obd.getDTC()) {
    Serial.println("DTCs found:");
    for (int i = 0; i < obd.dtcCount; i++) {
      Serial.print("Code: ");
      Serial.println(obd.dtc[i]);
    }
  } else {
    Serial.println("No DTCs found");
  }
  delay(5000);
}

This code initializes the OBD2 connection, retrieves any stored DTCs, and prints them to the Serial Monitor.

5.4 Clearing DTCs with Arduino Due

Clearing DTCs can be done using the clearDTC() function in the OBD2 library. However, it’s important to note that clearing DTCs without addressing the underlying issue will only result in the codes reappearing.

#include <OBD2.h>

OBD2 obd;

void setup() {
  Serial.begin(115200);
  while (!Serial);

  if (obd.begin()) {
    Serial.println("OBD2 connection successful");
  } else {
    Serial.println("Failed to connect to OBD2");
  }
}

void loop() {
  if (obd.clearDTC()) {
    Serial.println("DTCs cleared");
  } else {
    Serial.println("Failed to clear DTCs");
  }
  delay(5000);
}

This code initializes the OBD2 connection and attempts to clear any stored DTCs.

5.5 Safety Precautions and Best Practices

• Install the CAN library in the Arduino IDE (e.g., the MCP_CAN library for MCP2515 CAN controllers).

Here’s an example of how to initialize CAN bus communication with Arduino Due:

#include <mcp_can.h>
#include <SPI.h>

// Define the CAN controller pins
const int SPI_CS_PIN = 10;

// Create an instance of the MCP2515 CAN controller
MCP_CAN CAN(SPI_CS_PIN);

void setup() {
  Serial.begin(115200);

  // Initialize CAN bus
  if (CAN.begin(MCP_ANY, CAN_500KBPS, MCP_8MHZ) == CAN_OK) {
    Serial.println("CAN bus initialization successful");
  } else {
    Serial.println("Error initializing CAN bus");
  }

  // Set mask and filter to receive all messages
  CAN.init_mask(0, 0x00000000);
  CAN.init_filter(0, 0x00000000);
}

void loop() {
  // Check for incoming CAN messages
  if (CAN.checkReceive() == CAN_MSGAVAIL) {
    unsigned long canId = CAN.getCanId();
    unsigned char len = 0;
    unsigned char buf[8];

    CAN.readMsgBuf(&len, buf);

    Serial.print("Received CAN message: ID = ");
    Serial.print(canId, HEX);
    Serial.print(", Data = ");
    for (int i = 0; i < len; i++) {
      Serial.print(buf[i], HEX);
      Serial.print(" ");
    }
    Serial.println();
  }
}

This code initializes the CAN bus and listens for incoming messages. You can then parse the CAN messages to extract specific vehicle data.
