Consider a commercial truck. The Electronic Brake Systems (EBS) ECU receives following message from some other ECU. Please explain this message. From where does some other module acquire the Suspect Parameters Number (SPNs) to send to EBS ECU. What does EBS do with the SPNs it receives?
Please consider steering electronic control unit (ECU). It has 6-pin CAN connector.
CAN L pin is connected to another CAN L pin in this 6-pin connector.
CAN H pin is connected to another CAN H pin in this 6-pin connector.
What are the reasons for above connections?
Consider an Electronic Control Unit (ECU) mounted in a vehicle. Let's say this ECU has Three CAN channels as follows:
CAN 1
CAN 2
CAN 3
Do these Three CAN channels have to be on different CAN networks? Another words, for example, CAN 1 and CAN 2 are never on the same CAN network?

Hi, guys I'm working with MCP2515 CAN Module and PIC18F series.I write a single byte data and read it back using SPI Protocol.
But I am unable to receive any data back.
here i have posted the code please check it and help me.
i connected two MCP2525 modules , so I think there is no problem with...
I was just trying to understand the CAN transceiver TJA1042T behavior during fault conditions:
CANH short to BATT
CANH short to GND
CANL short to BATT
CANL short to GND
I'm powering on the transceiver IC and giving the TXD signal from the signal generator (a 0-5V square wave) and I'm...
Hi guys, I've been studying CAN protocol for a while and I can't understand Filter and Mask in CAN description . I'm referring PIC24H series for studying ECAN.
my Question is
1. why do we need Mask register?
2. won't the filter register be enough to accept incoming CAN messages?
3.How does...
i am working on CAN messages in haima s5 and i want to recognize all of the activated light faults in ICM (instrument control system).
can you tell me which module activates "engine exhaust fault lamp"?
