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.

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

DTC B2262 will set if LDCM detects left mirror horizontal position sensor signal voltage range less than 0.10 volt or more than 4.78 volts for more than 2 seconds. DTC B2262 will store as a history code in LDCM memory. No driver warning will be displayed. DTC can only set as history even if malfunction is current.

Under all fault conditions, DTC B2262 will clear automatically when LDCM no longer detects left mirror horizontal 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 Instrument Panel Cluster (IPC) clearing DTCs feature.
