Most new vehicles use high-speed CAN (ISO 11898-2) for powertrain and safety, and low-speed CAN for body controls. However, LIN bus has replaced low-speed CAN in many cost-sensitive applications.
ISO 11898-3 is a part of the ISO 11898 series of standards for CAN communication. This particular part focuses on the low-speed, fault-tolerant, medium-dependent interface. It specifies the requirements for the physical layer of CAN systems that operate at low speeds and are designed to be fault-tolerant. iso 11898-3 pdf
