Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Security Indicator
The security indicator on the instrument cluster is controlled by both the VTD system and the CTD system. The security indicator is displayed on the instrument cluster.
The indicator is controlled by the instrument cluster when commanded by the theft deterrent controller module via the class 2 serial data line.
- The VTD system commands the instrument cluster to control the indicator only when the ignition switch is ON. The VTD System uses the indicator as a malfunction indicator.
- The CTD system commands the instrument cluster to control the indicator only when the ignition switch is OFF. The CTD System uses the indicator to identify system status.
