Identifying Alarm Components
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
See the following list to identify the various components.
Ultrasonic sensor
- Ultrasonic sensors can be identified by two small microphones at the top of each B-post.
Movement sensor
- If the car is a cabriolet or a coupe, it is always equipped with a mass movement sensor and no ultra sound-or glass breakage sensor if it has an alarm.
Glass breakage sensor
- The glass breakage sensor is identified by removing the passenger side loudspeaker grille on the dashboard. If the car has a glass breakage sensor there is a small microphone located beside the loudspeaker.
Resistive wire
- Resistive wires in the rear windows of 5-door models are identified by an additional wire in the rear windows (additional to the antenna strip).
Tilt sensor
- The tilt sensor is located in the cargo compartment in the right wheel well and can be identified on 4-door cars by folding up the carpet and removing the side panel on the right hand side of the cargo compartment.
On 5-door cars, fold up the floor hatch and remove the cover over the wheel well to locate the tilt sensor.
Alarm horn/siren
- The alarm is equipped with either an alarm horn or a siren. The alarm horn is located in the engine compartment on the firewall beside the upper engine mounting. If there is an alarm horn, the car is not equipped with a siren. If the car does not have an alarm horn it is equipped with a siren.
