B2285 CHEVROLET Description

The Driver Door Module (DDM) and Passenger Door Module (PDM) each have a high and low power feed. The low power feed, battery 1, is used to provide power for the door module logic and internal driver operation. The high power feed, battery 2, is used to provide power for systems that draw higher amounts of current. The door modules monitor the voltage level at battery 1 and battery 2 to determine if the voltage level is out of range. If the voltage level is out of range, a Diagnostic Trouble Code (DTC) is set.
