Code C0282 GMC Description
The integrity of the MPA switch is tested by the Electronic Brake Control Module (EBCM). The MPA is partially discharged during system initialization to open the switch and then recharged to close the switch. The EBCM continues to monitor the switch to ensure the MPA remains charged. Provided the VSES is not activated, the MPA should remain charged for the entire ignition cycle. If the MPA switch opens within 5 minutes of closing, a fast leak down condition is detected. If the MPA switch opens after 5 minutes has passed, a slow leak down condition is detected.
