Troubleshooting
Tree SysFile IDs Causes (numbered in order of likely occurrence)
24 0x3405
1. Air in the cooling circuit.
2. Cooling liquid flow too low or nil (cooling pump issue).
3. Cooling liquid temperature too high.
4. Wrong cooling agent mixture used
– (can create dust/rust in the
cooling circuit.
5. Defective MCU .
25 0x3111
0x4000
1. Software problem. Update inverter software.
2. Defective MCU
26 0x3113
1. Other error causes the system to move in defective while in high
speed (back EMF too high to maintain DC bus under the high voltage
limit).
