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.
THATCHAM Alarm System (Export Only)
The Thatcham Alarm Module monitors the vehicle doors, liftgate, hood and the interior of the vehicle for unauthorized operation. The vehicle doors, liftgate, and hood use ajar switches as inputs to the BCM to indicate their current status. The interior of the vehicle is secured by the use of Intrusion Sensors. The Intrusion Sensors are used as inputs to the Thatcham Alarm Module to report any motion in the interior of the vehicle. The alarm activates by sounding the siren, flashing the hazard lamps, and the VTSS Indicator Lamp.
Arming
Before arming, all doors, liftgate, and the hood must be completely closed. The system can only be armed by locking the doors with the RKE transmitter.
Disarming
To disarm the alarm system, use the RKE transmitter or turn the ignition on with a valid ignition key. This will also halt the alarm once it has been activated.
