CAN and LIN are two different communication protocols used in PTC coolant heaters and other scenarios.

CAN (Controller Area Network) is a high-speed, reliable, multi-node serial communication protocol, mainly used for high-speed data transmission and control in the field of automotive electronics; while LIN (Local Interconnect Network) is a low-speed, simple, low-cost serial communication protocol mainly used for low-speed data transmission and control in the field of automotive electronics.

CAN lines and LIN lines can be distinguished from the following aspects:

1. Speed: The speed of CAN lines is much faster than that of LIN lines. The maximum speed of CAN lines can reach 1Mbps, while the maximum speed of LIN lines is only 20Kbps.

2. Function: CAN lines are usually used for high-speed data transmission and control, can support multi-node communication, and have high reliability and anti-interference capabilities; while LIN lines are usually used for low-speed data transmission and control, mainly for simpler control tasks.

3. Application scenarios: CAN lines are usually used in application scenarios that require high-speed, reliable, and multi-node communication, such as engine control, body electronic systems, etc.; while LIN lines are usually used in application scenarios that require low-speed, simple, and low-cost.

CAN lines and LIN lines are both communication protocols widely used in the field of automotive electronics. They each have different characteristics and application scenarios. In actual applications, it is necessary to select the appropriate communication protocol according to specific needs.
