DTC Description

WARNING: This page is about a different car, the 2015 Hyundai Sonata. However, it is still accessible from the selected car via links, so may be relevant.

The failure is detected if the pressure sensor value is under normal range.

Also, the failure can be detected in case that drivers try to repeat excessive braking because it renders the accumulator pressure decrease in spite of the charging.
