Service Manual
For operational fault codes 0-40-0 and 0-40-1 or power board faults 3-11-0 and 3-11-1 (CSA only)
1. Remove PFC temperature sensor connector (J16) from power board.
2. Check the resistance between pins 1 and 2 on the plug. Resistance should be about 5.5 kΩ.
3. If the resistance is incorrect, replace the PFC IGBT, gate drive wires, and PFC temperature sensor wire.
4. If the value is correct, measure resistance between pins 1 and 2 on the power board with the temperature sensor
disconnected. The resistance should be about 4.7 kΩ.
5. If the value is correct, replace DSP board.
6. If the value is incorrect, replace power board.
