A/C Compressor Capacity Inspection
WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition "OFF".
- Disconnect the auxiliary battery (-) connector.
- Remove the safety plug, and check that the high voltage terminal voltage is less than 30V.
- Disconnect the A/C connector.
- Set the multi-meter to CAP measuring setting.
- Monitor specification below.

Good
- Measure the Inverter CAP and LDC CAP voltage. If voltage does not change, inspect high voltage cable. If CAP voltage change rate is not sufficient, inspect for inverter terminal of PRA.
- If no problems were found with the circuits or connectors, replace the HPCU or A/C compressor and then Go to "Verification Of Repair " procedure.
No Good
- If no problems were found with the circuits or connectors, replace the A/C compressor and then Go to "Verification Of Repair " procedure.
- Inspect for low voltage cable. Check for fault on wiring harness between BMU and PRA. If fault is found, replace the low voltage cable.
- If BMS relay control circuit is detected, replace the BMU and Go to "Verification Of Repair " procedure.
