Diagnostic Aids
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.
The following conditions may cause an intermittent malfunction:
- Intermittent open, short to ground or short to voltage in Dark Green, Purple, Tan, Brown/White or Black wires between Seat Control Module (SCM) and seat adjuster.
- Seat vertical or horizontal sensor is shorted internally.
If SCM is unable to determine correct vertical or horizontal position, manual power seat functions will still operate, but SCM will not be able to correctly recall position of seat when memory button is pressed. Using scan tool, select SCM data display and monitor seat position sensor data. Move power seat switch vertically and horizontally while monitoring position sensor data. This checks if the seat position sensor supply voltage is within range in different positions.
