3. Reading Diagnostic Trouble Codes (DTCs)

3.1 Accessing the Code Reading Function

1. Navigate to the Diagnostics Menu: From the main menu, select the “Diagnostics” or “Read Codes” option using the arrow keys and press “Enter.”
2. Initiate Code Reading: The scanner will begin communicating with the vehicle’s computer to retrieve DTCs. This process may take a few seconds.

3.2 Understanding DTCs

DTCs are five-character codes that indicate specific problems within the vehicle’s systems. The first character identifies the system:

• P: Powertrain (engine, transmission)
• B: Body (interior, exterior)
• C: Chassis (brakes, suspension)
• U: Network (communication systems)

The subsequent characters provide more specific information about the fault. For example, P0300 indicates a random or multiple cylinder misfire.

3.3 Interpreting the Codes

The Bosch 1050 OBD2 scanner displays a brief description of each DTC. For a more detailed explanation, consult the CodeConnect database or a reliable online resource. Common codes include:

• P0171: System Too Lean (Bank 1)
• P0301: Cylinder 1 Misfire Detected
• P0420: Catalyst System Efficiency Below Threshold (Bank 1)
• P0442: Evaporative Emission Control System Leak Detected (Small Leak)

3.4 Recording the Codes
