PDO timeout of pump motor
controller
1. Software problem;
2. CAN bus communica-
tion error.
1. Update the software to the correct version,
and ensure the bus free of interference;
2. Ensure the bus terminal resistance is 60
ohm, the bus voltage approx. 2.5V;
3. Ensure the devices on the bus are cor-
rectly connected;
4. Check the on-bus devices are correctly
programmed;
5. Use the exclusion method to replace the
failed devices.
