Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

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.

When the PCM detects a continuous short to ground in the 2nd brake control solenoid circuit, then DTC P0787 sets. DTC P0787 is a type A DTC.
