Error Code P0BCB: What It Means & What To Do?

<<See All OBD Codes

What does P0BCB error code signify? What are its symptoms? Are these questions popping in your mind? Then you are at the right place for a solution. Hybrid battery pack cooling fan is monitored by the engine control module (ECM). The error code will be set in the vehicle if the factory specification is not correctly met by the hybrid battery pack cooling fan.

The hybrid battery pack cooling fan will draw air through the hybrid battery pack so that the temperature of the high voltage battery can be brought under control. The starter or the generator control module will control the fan. If the cooling fan is not functioning as expected, the module will identify it and then the P0BCB error code will get stored.

What causes this problem with the Hybrid Battery Pack Cooling Fan Sense Circuit Intermittent/Erratic?

• The hybrid battery pack cooling fan might be damaged.
• You will see an opening or short-circuit in the hybrid battery pack cooling fan harness.
• The bad electrical connection in the hybrid battery pack cooling fan circuit.

1. Hybrid Battery - If the hybrid battery is damaged, then you will notice a drop in the battery bars with no usage. Even at times, you will hear strange noises from the engine. This is an indication that the hybrid battery needs a quick replacement.
2. Car Cooling Fan - If the engine starts overheating, then the cooling fan will start malfunctioning. Change it as soon as possible to avoid further troubles
3. Car Battery - Swollen battery is an indication that the battery is defective. Get a new battery from Parts Avatar and replace it as quickly as possible.
4. Starter - If the starter motor is broken, then the vehicle will find the trouble as you start the vehicle. Replace it quickly to avoid the P0BCB error.
5. Auto Generator - Generators are used for charging the battery and it supplies power to the electrical system when the engine is running. A damaged generator needs quick replacement so that the vehicle functions smoothly.
6. Engine Control Module - Is the performance of the engine very poor? Does your engine keep stalling very often? Then the ECM might be faulty which needs replacement as soon as possible.
7. Powertrain Control Module - The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0BCB code to be stored:

• Initially, the mechanic will use a scanner to check for the stored error codes.
• He will now connect a scanner to the diagnostic port of the vehicle and recover the stored codes and freeze frame data.
• These data are usually obtained as they can help him with the further diagnostic process.
• Firstly, the mechanic will check the hybrid battery and battery. If there are any faults or defects, it will be repaired.
• If there are no errors, then the components like cooling fan, voltage battery, starter, generator, etc will be visually checked and examined to see if there are any faults or stored error codes.
• If there are any errors, the mechanic will repair them immediately.
• As a final step, the mechanic will inspect the engine control module if it is broken or damaged. If it is broken, the mechanic will carry out the repair process.
• After every component is repaired and when the diagnosis process is properly done, the mechanic has to test drive your vehicle again see if the engine light turns on or if the error code still appears.
• This can help him to locate the area as to where the error has been stored in the vehicle.

Common Mistakes When Diagnosis the P0BCB Code

• The faulty high voltage battery pack cooling fan.
• Troublesome electrical wires.
• Starter/generator control module might be faulty.
