Kia Soul EV: High Voltage Battery Control System / Runaway Arresting Device (RAD) Repair procedures

Kia Soul EV (PS EV) 2015-2020 Service Manual / EV Battery System / High Voltage Battery Control System / Runaway Arresting Device (RAD) Repair procedures

Inspection

•	Be sure to read and follow the “General Safety Information and Caution” before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries

•	Be sure to shut off the high voltage before doing any work related with the high voltage system(Refer to "High Voltage Shut-off Procedure"). Failure to follow the safety instructions may result in serious electrical injuries.

When removing the battery pack assembly to inspect the battery system, it can be connected to vehicle by using the SST 0K918-E4100, 0K375-E4100, 0K375-E4200.

1.	Turn the ignition switch OFF and disconnect the auxiliary batter negative (-) terminal.

2.	Shut off the high voltage. (Refer to Battery Control System - "High Voltage Shut-off Prcedure")

3.	Remove the high voltage battery upper case. (Refer to High Votlage Battery System - "Case")

Measure the combined resistance of RAD terminal.

Specification : Less than 3 ? (20°C)

Measure the resistance of each RAD.

Specification : Less than 0.375? (20°C)

When installing the RAD harness, be sure to check if the connector is installed on the correct position.

[If not correct]

1. Failure of precharging

2. RAD malfunction (misrecognize that the high voltage battery is swollen)

[Main inspection items]

1. Check that the RAD switch is facing down.

2. Be careful not to reverse the battery No. 1 module RAD connector (2 pins) and the BMS extension connector (1 pin).

3. Be careful not to reverse the battery No. 8 module RAD connector (2 pins) and the BMS extension connector (1 pin).
