1. Checklist :

 

1) Is the PFC Shunt(“A”) resistance value correct? Check the resistor is opened

 

2) Is the IPM Shunt(“B”) resistance value correct? Check the resistor is opened

 

3) Is there no short or open around “C”?

2. Troubleshooting procedure

NO

NO

YES

YES

Restart after power off.

Is the PFC shunt and IPM

shunt resistance value correct?

Is the current sensor error appeared again?

Exchange the Outdoor PBA

Exchange the Outdoor PBA

Terminate the service
