• ISO 9141: An older protocol used in many European and Asian vehicles for diagnostic communication.
• SAE J1850: A protocol used in many older American vehicles for diagnostic communication.

3.2 Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are codes stored in the vehicle’s ECU that indicate a specific fault or malfunction in a system. Scan tools can retrieve these codes to help technicians identify the source of the problem.

• P Codes (Powertrain): Relate to the engine, transmission, and related components.
• B Codes (Body): Relate to body systems such as airbags, power windows, and central locking.
• C Codes (Chassis): Relate to chassis systems such as ABS, traction control, and suspension.
• U Codes (Network): Relate to communication issues between ECUs.

3.3 Live Data and Freeze Frame Data

Scan tools can display live data streams from various sensors and components in the vehicle, allowing technicians to monitor performance in real-time. Freeze frame data captures the sensor values at the moment a DTC was triggered, providing valuable information for diagnosing intermittent issues.
