Circuit Description

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Right Door Control Module (RDCM) determines vertical position of right mirror from a signal sent by vertical position sensor. RDCM commands mirror memory recall settings based on voltage level RDCM receives back from vertical sensor. RDCM provides a 5-volt supply, a right-side mirror vertical position signal and a ground to vertical position sensor. When a memory setting is recalled, RDCM will command right mirror motor to move to a stored position sensor voltage previously set. RDCM monitors right mirror vertical position signal circuit and can determine if voltage level received is out of range.

DTC B2265 will set if RDCM detects right mirror vertical position sensor signal voltage range less than 0.10 volt or more than 4.78 volts for more than 2 seconds. DTC B2265 will store as a history code in RDCM memory. No driver warning will be displayed. DTC can only set as history even if malfunction is current.

Under all fault conditions, DTC B2265 will clear automatically if RDCM no longer detects left mirror vertical position sensor signal voltage range less than 0.10 volt or more than 4.78 volts for more than 2 seconds. Current and history DTCs can be cleared using scan tool or IPC clearing DTCs feature.
