OBD2 Connector Pinout, Types & Codes(Explained)
OBD II Connector Pin Diagrams. OBDII compliant vehicles can use up to five different protocols • SAE J1850 PWM • SAE J1850 VPW • ISO9141-2, • ISO14230-4 (KWP2000), and • ISO 15765-4/SAE J2480. Each protocol has some required pins and some optional pins. So you can tell which protocol your vehicle has by looking at the diagrams below.
OBD2 Technology The Definite Interpretation OBD Solaris
The OBD2 pinout depends on the communication protocol; The most common protocol is CAN (via ISO 15765), meaning that pins 6 (CAN-H) and 14 (CAN-L) will typically be connected; OBD2 connector - type A vs. B. In practice, you may encounter both the type A and type B OBD2 connector. Typically, type A will be found in cars, while type B is common.
