Test Description

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table:

  1. 2. This test determines the status of the column switch using a scan tool. The scan tool will display the column switch status as in, button pressed toward driver, and Idle, button released.
  2. 3. This test checks if the column switch is shorted to ground or stuck. If the column switch status changes from in to Idle when the column switch is disconnected, then the switch assembly must be replaced.
