Ignition Switch Off Mode

WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

When the operator turns the ignition switch to the OFF position, the following occurs:

  1. All outputs are turned off, unless 02 Heater Monitor test is being run. Refer to Emission for On-Board Diagnostics.
  2. No inputs are monitored except for the heated oxygen sensors. The PCM monitors the heating elements in the oxygen sensors and then shuts down.
