Kia Niro: High Voltage Battery Control System / Pre-Charge Resistor Repair procedures

Removal
  

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.

1.

Shut off the high voltage circuit.

(Refer to Hybrid Control System - “High Voltage Shutoff Procedure”)

2.

Remove the power relay assembly.

(Refer to High Voltage Battery System - "Power Relay Assembly (PRA)")

3.

Insert a screwdriver or an awl (B) into the hole (A).

4.

Lift the pre-charge resistor (D) in the direction of arrow (C).

5.

Remove the pre-charge resistor (A).

Inspection
1.

Remove the pre-charge resistor.

(Refer to High Voltage Battery Control System - "Pre-Charge Resistor")

2.

Check for continuity between the terminals using an ohmmeter.
