the Fast Controller Area Network (FCA) and the Body Controller Area Network (B-CAN) (F-CAN)
Information is shared between various Electronic Control Units via the Fast Controller Area Network (FCAN) and the Body Controller Area Network (B-CAN) (ECUs). For convenience-related features and other uses, B-CAN connection operates at a reduced speed (33.33 kbps). For “real time” operations like fuel and emissions data, F-CAN information travels at a quicker speed (500 kbps). The gauge control module converts data from B-CAN to F-CAN and from F-CAN to B-CAN so that both systems can share it. The Gateway Function is what we refer to as.

Honda system capable?
Both a High Speed CAN system and a Low Speed CAN system are present in my 2012 Honda Odyssey. High speed CAN is referred to as F-CAN in Hondaspeak, and low speed CAN is referred to as B-CAN and operates at 125 kbps. Climate control, music, door locks, the blind spot warning system, and other “less important” features are managed by B-CAN. The instrument cluster is how B-CAN and HS-CAN are connected. It’s interesting to note that B-CAN error codes can be pulled without a scan tool.
I believe that B-CAN does not have a diagnostic connector, thus in order to access the system, I would have to splice wires together and cobble a Carloop into the mix.
A picture of some of the systems that are controlled by F-CAN and those that are controlled by B-CAN is shown below.

What exactly is FCAN network?
A data-communication protocol called CAN FD (Controller Area Network Flexible Data-Rate) is frequently used for transmitting sensor data and control information across two wire connections between various components of electronic instrumentation and control systems. Modern high performance automobiles employ this protocol. The original CAN bus protocol, which was outlined in ISO 11898-1, is expanded upon by CAN FD. [1] It was first proposed in 1999 to overclock a portion of the frame and enlarge the payload. [2] For usage in contemporary automotive Electronic Control Units, Bosch developed CAN FD[3], which was introduced in 2012 and addresses the need to improve data transfer rate up to five times quicker and with larger frame/message sizes (ECUs). The CAN FD protocol, like the original CAN protocol, is made to properly transmit and receive sensor data, control orders, and data errors between electronic sensor devices, controllers, and microcontrollers. Although CAN FD was primarily created for use in high-performance automotive ECUs, the widespread use of classic CAN across a number of industries will eventually result in the inclusion of this improved data-communication protocol in a number of other applications, including electronic systems used in robotics, defense, industrial automation, underwater vehicles, medical equipment, avionics, down-hole drilling sensors, etc.

How is CAN bus implemented?
Vehicles are intricate machinery with several interconnected parts that require communication with one another. A Controller Area Network was created as a result. Tom Denton describes the technology’s operation.
These days, a Controller Area Network (CAN) bus is a standard component of all contemporary automobiles, even the newest electric vehicles. The engine, transmission, and brakes may all communicate with one another thanks to the vehicle’s electronic communications system. It serves as the brain of the automobile.
The CAN bus, developed by Bosch and introduced on the Mercedes-Benz S-Class in 1991, initially connected five engine control units (ECUs) with the goal of enhancing performance and safety by facilitating a quicker exchange of real-time data within the vehicle.
These messages can be combined (or multiplexed) using the CAN bus network, which requires less electrical wire (and weight) overall. It was an improvement over the previous technology, which consisted of two-way receivers and transmitters that were incapable of handling many simultaneous communications.
Any networked device can construct a “data frame,” the common message format, and transmit it consecutively across a CAN bus. When multiple devices broadcast at once, the one with the highest priority transmits first while the rest wait. All ECU nodes in the network receive frames, which are composed of an ID, a message, and additional components like error correction bits.
Most automobiles include a twisted pair of tiny wires called CAN high (CAN-H) and CAN low that make up the physical network (CAN-L). Additionally, fiber optics and coaxial wires can be employed.
Most automobiles today include multiple networks for the body, the powertrain, and the infotainment system, for example, with a gateway to regulate data traffic. Nowadays’ cars may contain dozens of ECUs, as opposed to the S-Class from 1991, including ones for the engine, the transmission, the airbags, the ABS, the traction control, and the stability control. The CAN bus enables real-time communication between various components, giving priority to the most crucial data and enhancing vehicle performance and safety.
Does a life of 0 mean there is no oil?
Here’s everything you need to know about the “oil life 0%” notice on your car’s dashboard if you’re concerned.
Your oil level is dangerously low if you see an oil life 0% warning. Up to 500 miles, you can continue to drive your car, but you should have an oil change as soon as you can by stopping at a service station. Driving your car over extended periods of time with little or no engine oil can harm the engine permanently.
Is 10% oil life acceptable?
The 15 and 10 percent oil life indicators serve as a reminder that it’s almost time to bring your car in for its scheduled maintenance. If the recommended maintenance is not carried out, negative mileage is displayed and starts blinking after 10 miles (16 km) or more of driving.
At 15%, should I change the oil?
For instance, just because your oil life indicator reads 15% doesn’t indicate you’re 15% from running out of oil. Instead, it indicates that the time for an oil change is getting closer by the day.
