Hippocampus can bus voltage is too low what happened?

The low voltage of the HIPPOCAMPUS can bus CAN be caused by a variety of reasons:
Power supply problem: It may be a failure of the power supply circuit or a loose power plug, causing the CAN bus voltage to be too low.
Node failure: A node on the CAN bus fails, causing the bus voltage to drop.
Line problem: The CAN bus line may be short circuit or open, resulting in low bus voltage.
Controller failure: Software or hardware failure of the controller CAN also cause the CAN bus voltage to be too low.
In view of the above possible causes, we can take appropriate measures to troubleshoot and repair:
Check whether the power circuit and power plug are normal, and replace the faulty parts if necessary.
Check whether each node on the CAN bus works properly. If there is a fault, repair it in time.
Check whether the CAN bus line is normal, and repair it in time if there is short circuit or open circuit.
Check whether the software and hardware of the controller are normal. If any fault occurs, repair or replace the controller in time.
During the troubleshooting and repair process, you need to pay attention to safety to avoid more serious faults or accidents caused by improper operations. At the same time, it is necessary to have a certain knowledge of automotive circuits and CAN buses in order to better understand and solve problems. If the fault persists, seek professional help.


Under normal circumstances, the hippocampus can bus voltage should be between 2.5V-3.5V, if the voltage is too low, it may be caused by poor contact of the can bus signal line or loose interface. In addition, it is possible that the voltage is too low due to the fault of the module or chip where the can bus is located. It is recommended to check whether the can bus connection is normal, and after eliminating the connection problem, professional instrument testing is needed to determine the specific cause of the fault.
