On a 2005-07 Chevrolet Corvette, Seat Recall or Exit Recall (memory) for the driver’s seat or steering wheel may be inoperative or have erratic operation. This could be the result of the Body Control Module (BCM) not recognizing the driver’s door position, either open or closed.
There are two switches in the door latch and two door inputs to the BCM from each door. The door inputs are the "Left Door Ajar" and "Left Door Open" data parameters. In order for the seat recall to function correctly, both door switch parameters must change state. Depending how the Tech 2 is navigated, only one of the two parameters may be located within the Tech 2.
Diagnostics > Select Model Year 2005, 2006 or 2007 > Passenger Car > Chevrolet > Y > Body and Accessories > Theft Deterrent > Data Display > Body Control Module > Keyless/Remote Start Data.
Inspect the "Left Door Ajar" input and "Left Door Open" input for proper operation. If either data parameter is not functioning correctly, refer to SI document 1602023 for the schematic or SI document 1631958 to begin the Diagnostic System Check.
