  • Regular maintenance tasks, such as oil changes, fluid checks, and filter replacements, are performed on the internal combustion engine, similar to traditional vehicles. Hybrid car services also include specific checks and maintenance for the hybrid components.

 Onboard Diagnostics (OBD) System:

  • The vehicle has a diagnostic connector, usually located near the driver's seat or under the dashboard. This connector allows external diagnostic equipment to communicate with the onboard computer.

Diagnostic Connector:

  • Mechanics and technicians use OBD scanners or code readers, which are handheld or computer-based devices, to connect to the diagnostic connector. These devices can read and interpret diagnostic trouble codes (DTCs) generated by the vehicle's computer.

OBD Scanner/Code Reader:

  • When connected to the vehicle, the OBD scanner retrieves DTCs stored in the computer's memory. Each code corresponds to a specific issue or malfunction detected by the OBD system.

Reading Diagnostic Trouble Codes (DTCs):

  • The technician interprets the DTCs to identify the nature of the problem. DTCs are standardized codes that provide information about the system or component experiencing issues.

Interpreting DTCs:

  • OBD scanners can also provide live data, allowing technicians to monitor real-time sensor readings. Freeze frame data, which captures sensor data at the time a DTC is triggered, helps diagnose intermittent issues.

Live Data and Freeze Frame Data:

  • After diagnosing the issue, the technician may choose to clear the DTCs from the vehicle's memory. Some issues are temporary, and clearing the codes can help determine if the problem persists.

Clearing DTCs (Optional):

  • Depending on the complexity of the issue, the technician may perform additional diagnostics, such as checking specific components, conducting visual inspections, or using advanced diagnostic tools.

Additional Diagnostics:

  • Once the issue is identified and repaired, the technician may re-scan the vehicle to confirm that the DTCs are no longer present. This ensures that the repair was successful.
