The 2001 Dodge Van OBD II port typically has 16 pins, each serving a specific purpose. Here’s a breakdown of the most common pins and their functionalities:
Pin 1: Ground – This pin provides a common ground reference for all signals passing through the port.
Pin 4: Chassis Ground – This pin provides a secondary ground connection for more stable and reliable communication.
Pin 5: Signal Ground – This pin acts as a ground reference specifically for signal lines, ensuring accurate data transmission.
Pin 6: Battery Positive – This pin provides a constant 12-volt power supply to the diagnostic tools connected to the port.
Pin 7: +12V with Ignition On – This pin provides a 12-volt power supply only when the ignition is turned on, powering the diagnostic tool while the engine is running.
Pin 10: CAN High (High-Speed Data Bus) – This pin is part of the Controller Area Network (CAN) bus system, responsible for high-speed data communication between various vehicle modules.
Pin 12: CAN Low (Low-Speed Data Bus) – This pin is also part of the CAN bus system and works in conjunction with Pin 10 to facilitate data exchange.
Pin 16: Data Terminal (K-Line) – This pin is used for communicating with the vehicle’s control units using a slow, single-wire communication protocol.
