# Kia Soul EV: Controller / Heater & A/C Control Unit (FATC) Repair procedures

Kia Soul EV (PS EV) 2015-2020 Service Manual / Heating,Ventilation, Air Conditioning / Controller / Heater & A/C Control Unit (FATC) Repair procedures

Self Diagnosis

1. | Self-diagnosis process

2. | How to read self-diagnostic code After the display panel flickers three times every 0.5 second, the corresponding fault code flickers on the setup temperature display panel every 0.5 second and will show two figures. Codes are displayed in numerical format

3. | Fault code display
(1) | Continuous operation : DTC code for one.
(2) | Continuous operation : DTC code for two or more.
(3) | STEP operation
A. | Same as continuous operation when normal or one fault code.
B. | DTC code for two or more.

4. | If fault codes are displayed during the check up, inspect possible causes of malfunction by referring to fault codes.
