Tamper Alert
WARNING: This page is about a different car, the 2006 Dodge Viper. However, it is still accessible from the selected car via links, so may be relevant.
Normally the VTA lamp will pulse once every 6 seconds when armed. If there is a tamper condition, the VTA lamp will quickly pulse twice every 6 seconds. When the system is disarmed, a VTSS tamper alert will sound the horn three times to indicate a tamper condition has occurred.
