Circuit Description

The RH Door Control Module (RDCM) has two main power feeds (high and low), and one main ground. The low power feed (battery 1) is used to provide power for the RDCM logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights etc.). For most functions, the RDCM will operate properly when vehicle system voltage is between 9.0-16.0 volts. The RDCM also monitors the voltage level at battery 1 and battery 2 circuits and can determine if the voltage level received is out of range. If the voltage level is out of range in either circuit, then a malfunction is present and a DTC will set.
