Circuit Description

WARNING: This page is about a different variant/trim than selected.

The 2nd brake control solenoid is located in the control valve body of the transmission. The powertrain control module (PCM) turns the 2nd brake solenoid ON or OFF, this controls the application or release of the reverse clutch, which in turn reduces shift shock between transmission shift points. If the 2nd brake solenoid malfunctions, the shift shock will be extremely noticeable.

When the PCM detects a continuous open in the 2nd brake control solenoid circuit, then DTC P0788 sets. DTC P0788 is a type A DTC.
