The P0BAC fault code indicates a high voltage issue in the circuit of the 23rd battery in a hybridelectric vehicle. The battery pack in these vehicles consists of 288 cells, grouped in parallel sets of three. There are a total of 96 cell groups connected in series, resulting in a nominal system voltage of 355 V DC. The battery cells are divided into three sections.

Section one contains batteries 67 to 96, section two contains batteries 43 to 66, and section three contains batteries 1 to 42. Each section is individually serviceable. The battery energy control module monitors the voltage of the cell groups through hybridEV battery interface control modules.

These modules encode the voltage readings and transmit them to the battery energy control module. If a fault condition is detected, the battery energy control module communicates this information to the hybridEV powertrain control module 2, which serves as the diagnostic trouble code host controller. In summary, the P0BAC fault code indicates a high voltage issue in the circuit of the 23rd battery in a hybridelectric vehicle. The battery energy control module monitors the voltage of the cell groups and communicates any fault conditions to the powertrain control module for diagnosis.

What are the possible causes of the automobile fault code P0BAC?

If you see the engine light on or the service engine soon warning light, the fault code P0BAC could be the culprit. This code is often caused by a faulty hybrid/electric vehicle battery pack or a faulty hybrid/electric vehicle battery interface control module. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed above for further troubleshooting.

How can I visually inspect the wiring harness and connectors to fix the P0BAC fault code?
