Owners of 2019 Chevy Equinox vehicles may experience the MIL on. The technician may find DTC P050F (brake booster weak vacuum) set in the ECM.

The condition may be caused by a software anomaly.

First test the brake vacuum system to verify that no leaks are present and verify braking performance. If no vacuum leak is found, reprogram the ECM with the latest software calibration.
