3. Power on the Scanner: Turn on the Launch scanner and wait for it to establish a connection with the vehicle’s computer.
4. Read Diagnostic Trouble Codes (DTCs): Navigate to the “Read Codes” or “Diagnostics” menu to retrieve any stored DTCs.
5. Interpret the DTCs: Use the scanner’s built-in database or online resources to look up the meaning of each DTC. For example, a P0300 code indicates a random misfire, while a P0171 code suggests a lean fuel condition.
6. Clear the Codes (Optional): After noting the codes, you can clear them to see if they reappear. This can help determine if the issue is intermittent or persistent.
7. Perform Further Diagnostics: Based on the DTCs, conduct additional tests, such as checking sensors, wiring, and components.

Interpreting Diagnostic Trouble Codes (DTCs)

DTCs are five-digit codes that provide information about the nature and location of a problem. The first character indicates the system (P=Powertrain, B=Body, C=Chassis, U=Network). The second character specifies whether the code is generic (0) or manufacturer-specific (1). The third character identifies the specific subsystem, and the last two characters indicate the specific fault, and understanding the structure of DTCs can help narrow down the potential causes of a problem.
| Character | Meaning | Example |
| :——– | :——————— | :—— |
| 1st | System | P |
| 2nd | Code Type | 0 |
| 3rd | Subsystem | 3 |
| 4th & 5th | Specific Fault | 00 |

Using Live Data to Diagnose Issues

Live data streaming allows you to monitor real-time parameters, providing valuable insights into how the vehicle is performing. For instance, monitoring the oxygen sensor readings can help diagnose fuel mixture issues, while tracking engine temperature can identify cooling system problems.
