NOTE: Even if the A/C is turned off, the electric compressor may operate to cool the high voltage battery. If the electric compressor operation sound is heard, verify the monitor value when there is no more operation sound. If the electric compressor operation sound is heard while verifying the monitor value, continue charging until there is no more operation sound. Did the monitor values increase?	Yes	Go to the next step.
4		No	Perform malfunction diagnosis according to the symptom troubleshooting for [NORMAL CHARGING DOES NOT START] of the hybrid system. (See NORMAL CHARGING DOES NOT START [e-SKYACTIV PHEV] .)
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?
