Backup Battery And Low-Voltage Disconnect: Kia
I-CAR · August 6, 2025 · Kia
Summary
This article outlines Kia's safety and deactivation procedures for vehicles equipped with a 12V Auxiliary Parking-Lithium Battery Module (P-LBM). Before disconnecting the main 12V battery, technicians must follow specific steps to ensure the P-LBM is deactivated and no residual voltage remains in the system.
What to do on the job
Before disconnecting the main 12V battery on equipped Kia models, disconnect the positive (B+) terminal, keep the hood or trunk open throughout the service, and wait at least 5 minutes for the system to fully de-energize.
How to use it
Use this document when writing estimates or supplements for Kia vehicles equipped with a P-LBM to justify the necessary labor and wait time (5 minutes) required to safely de-energize the electrical system. Refer to Kia Pitstop document PS781 on kiatechinfo.com. Note that pre-repair scanning is critical, as any DTCs related to the hood or trunk must be resolved first because they can interfere with the proper deactivation of the P-LBM.
