SECURITY Indicator: Notes

2006 Chevrolet SSR AutomaticSECTION Notes

The SECURITY indicator on the instrument cluster is controlled by both the VTD System and the CTD System. The SECURITY indicator is controlled by the body control module (BCM) through the class 2 data line.

  • The VTD System contained in the BCM commands the instrument cluster to control the SECURITY indicator only when the ignition switch is ON. The VTD System uses the indicator as a malfunction indicator.
  • The CTD System also contained in the BCM commands the instrument cluster to control the indicator only when the ignition switch is OFF. The CTD System uses the SECURITY indicator to identify system status.
