P0B72 - OBD Trouble Code

<<See All OBD Codes

Stressed? Don’t know how to start? Well, we have it all! Here’s how you can easily solve the error code P0B72. “Hybrid battery voltage sense "L" circuit” is generally in known as the OBD-II code increased fuel consumption. Numerous mini-batteries connected together embody the high voltage battery pack. Whenever the high voltage control module notifies an error with more than one battery packs that high voltage battery assembly is made of, the code P0B72 is stored by the high voltage control module.

One can observe a total of 288 cells making up the hybrid/electric vehicle battery pack. Welded together in uniformity, there are groups of three cells formed. An aggregate of 96 cell groups are present in the hybrid/EV battery pack assembly. These individual cell groups are ranked at 3.7V for a nominal system voltage of 355 V direct current. Further the groups can be seen branched into three individual sections. The battery section one holds the first 90 cells/30 cell groups. This section is situated near to the cowl and consists of batteries ranging from 67 to 96. Next is the battery section two (found behind the section one) composed of 72 cells/24 cell groups and contains batteries 43 to 66. Lastly, the section number three is known as the transverse battery section. Constituting the remaining 126 cells/42 cell groups, it contains batteries from 1 to 42. All the three battery sections can be serviced individually.

The battery energy control module performs the function of monitoring the voltage of the 96 battery cell groups through the four hybrid/EV battery interface control modules. There are also voltage sense circuits that are connected to each individual cell group. Ending at a connector located on the top surface of the battery section, each of these sense circuits are connected to individual cell group. The codifying of the voltage reading is done by the hybrid/EV battery interface control module and is further transmitted by the battery control harness to the battery energy control module. One hybrid/EV battery interface control module is positioned over the battery sections one and two, and two hybrid/EV battery interface control modules are connected with battery section three.the list of components that can be serviced include the hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module.

A fault condition is sensed by the battery energy control module. The battery energy control module diagnostics and system status to hybrid/EV powertrain control module 2 the through serial data. The hybrid/EV powertrain control module 2 mainly controls the diagnostic trouble code information.

What causes this problem with the Hybrid Battery Voltage Sense "L" Circuit?

• A distorted hybrid/electric vehicle battery pack
• A damaged hybrid/electric vehicle battery interface control module

1. Hybrid battery - Stressed? Well, your hybrid battery can trigger a whole lot errors including a sluggish engine crank (car taking more than normal time to start), the illumination of all the dashboard lights along with a low battery fluid level. This not only hampers the system but also damages other components located in close proximity. We advise you to change yours right away. Tune into Parts Avatar now!
2. Hybrid battery pack - Well, due to a defect in your hybrid battery pack you may notice a corrosion in the case of the car batteries (which can be hazardous for other components as well) and also release of excessive heat not only reduces the lifespan of the hybrid battery packs but also the entire system. Repair or replace now.
3. Hybrid battery voltage sensor - Hybrid battery voltage sensors installed have a lot going on even while we fail to notice them. A possible failure in the hybrid battery voltage sensor can damage or drain the electrical wirings and components further requiring an expensive repair. We recommend to you to change yours from Parts Avatar now. What are you waiting for?
4. Battery cable - Overheating signs, a foul smell and a malfunction in the voltmeter are accompanied because battery cables that are corroded or disconnected. So in order to avoid stoppages in your journey get your battery cables changed. Tune into Parts Avatar now! 
5. Battery assembly - The battery assemblies installed perform the task of connecting the battery cables to the battery. While they are damaged the there are increased chances of a possible failure in the entire system. Difficulty in starting the vehicle and also rapid clicking while the vehicle starts is likely to be observed as initial signs of a failure in the battery assembly. Mend or restore yours now from Parts Avatar.
6. Battery control module - If your battery control module is damaged you are likely to experience faults in all the electrical components installed in your vehicle. This minor damage is responsible for slowly sprouting errors in the entire system. This leads to expensive repairs that are time consuming as well. Change or repair now!
7. Powertrain control module - A damaged PCM? Don’t know till what extend it can damage your system? Well, a fault in the powertrain control module brings in issues like a malfunction in the functioning of the entire engine, also the sparks and ignition timing from the spark plugs are controlled and received by the PCM. so to avoid a whole lot of repairs, we simply advise you to change your PCM now. Log into Part Avatar for best quality PCMs at the best prices.
8. Exhaust system parts - You are likely to notice smoke coming out of the system if you don’t change your exhaust system parts right away when they are diagnosed as defective. This is harmful not only for the system but also for the plastic parts located nearby. Parts Avatar is just the right place for you that offers the excellent quality products at the prices you have always been looking for.
9. Battery smart unit - Battery leak, very slow engine cranks and corrosion in the electrical components located around the battery smart unit are likely to be experienced. We have got you the perfect solution! Tune into Parts Avatar for purchasing top notch battery smart units.

Well, if you are looking to know about the common symptoms related to this error code P0B72, we are have worked out a small list to help you discover this error code with your vehicle.

It is essential to diagnose this fault code. Here are some steps which a technician should follow for diagnosing the problem that triggered a P0B72 code to be stored:

The technicians should make use of a device called an OBD-II scanner. This scanner should be connected to the onboard computer inside of the vehicle. It will then retrieve data from the vehicle to determine what issues might be present in the vehicle. The technician will likely first clear the code and then retest the vehicle. If there is an issue, the code will reappear. From that moment, the technician can start to narrow down the actual cause and determine what needs to be done to repair the vehicle.

Common mistakes when diagnosing the P0B72 Code

Listed here are a few basic mistakes that we advise you to avoid while performing the diagnosis:

• A high voltage battery connection failure
• A faulty high voltage battery assembly
• Wiring malfunction
