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.
If DTC does not reset after code is cleared, problem may be intermittent. While performing tests, move wires and connectors. Following conditions may also cause an intermittent malfunction:
- Intermittent open or short to ground in Dark Green or Purple wire circuits between left seat lower motor and SCM.
- An intermittent open, short to voltage or short to ground in ground wire circuit (Black wire).
- Horizontal position sensor is open or shorted internally.
If SCM is unable to determine correct horizontal position, manual power seat functions will still operate, but SCM will not be able to recall correct seat memory seat settings. Using scan tool, select SCM data display and monitor horizontal position data. Move power seat horizontally in both directions while voltage range should vary and stay between 0.10-4.78 volts depending on position of seat. This will check if horizontal position sensor is shorted in different positions.
