Confused? Too many big words? Don’t know where to start comprehending from? Not anymore, Parts Avatar is here to the rescue! Here we have mentioned all that you need to know about the OBD error code P0AAB. This OBD-II code high voltage system may not operate is also at times referred to as a hybrid battery voltage isolation sensor circuit intermittent/erratic. It can be seeing that the high voltage system utilizes a battery voltage isolation sensor that is built within the battery control module. This battery isolation sensor performs the function of monitoring the separation of the high and low voltage systems. When at times, the sensor fails to operate, the code P0AAB is stored. Mostly, the high voltage system gets disabled too.

It is notable that the power management control ECU constantly plays the role of regulating the battery smart unit. Also, it identifies the insulation defects present in the high-voltage system.

Want to diagnose the error code P0AAB? Well, then you should follow these steps in order to diagnose this fault code:

An updated OBD-II trouble code scanner should be applied to diagnose this trouble code P0AAB. The scanner should be used to check and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be test driven to see if the code persists. If the code vanishes it could likely be due to a malfunctioning diagnose or may display an intermittent issue.

Common Mistakes When Diagnosing the P0AAB Code

Only for you we have listed here a few common mistakes that should be avoided while the diagnosis procedure is being performed:

• It should be noted that before performing the repairs the mechanic should go through the system thoroughly, as at times he may end up performing major repairs that are expensive and time taking while the code could have been solved by just repairing some minor faults.
• A malfunction in the wiring.
• We advise you to leave the procedure in the hands of a trained technician as there is a bulk of circuitry involved.
