The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services. These factors will determine the overall cost of diagnosing and fixing the p0ba0 fault code.

The P0BA0 fault code refers to a performance issue in the 21st circuit of the HybridElectric Vehicle battery. The battery pack consists of 288 cells, grouped in parallel sets of three.

There are a total of 96 cell groups connected in series, with each group rated at 3.7V. The nominal system voltage is 355V DC. The battery cells are divided into three sections. Section one has 90 cells (30 cell groups) located adjacent to the cowl, batteries 67 to 96.

Section two is behind section one, with 72 cells (24 cell groups) from batteries 43 to 66. Section three is transverse and contains the remaining 126 cells (42 cell groups) from batteries 1 to 42. 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.

The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2. If a fault condition is detected, the battery energy control module will trigger the P0BA0 fault code, indicating a performance issue in the 21st circuit of the HybridElectric Vehicle battery.
