The automobile fault code p0bbb has an estimated repair time of 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for this type of repair.

The P0BBB fault code indicates a high voltage condition in the HybridElectric Vehicle battery circuit 26. 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), section two has 72 cells (24 cell groups), and section three has 126 cells (42 cell groups).

Each section is individually serviceable. The battery energy control module monitors the voltage of the cell groups through hybridEV battery interface control modules. Voltage sense circuits are attached to each group, and the readings are transmitted to the control module. If a fault condition is detected, the battery energy control module communicates it to the hybridEV powertrain control module 2 through serial data. The powertrain control module is responsible for diagnostic trouble code information.

What are the possible causes of the automobile fault code p0bbb?

If you see the engine light or service engine soon warning light on, the fault code P0BBB 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 a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the fault code p0bbb?

To fix fault code P0BBB, 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. This can help identify any issues with the hybrid/electric vehicle battery pack or the battery interface control module. Don’t forget to check the “Possible Causes” listed above for further troubleshooting.

What should I look for when checking for damaged components and connector pins to resolve the fault code p0bbb?

When dealing with the fault code p0bbb, which is indicated by the Engine Light or Service Engine Soon Warning Light being ON, it is important to check for damaged components and connector pins. This fault code is commonly caused by a faulty Hybrid/Electric Vehicle Battery Pack or a faulty Hybrid/Electric Vehicle Battery Interface Control Module. To resolve the issue, visually inspect the related wiring harness and connectors, paying close attention to any signs of damage such as broken, bent, pushed out, or corroded connector pins.
