Where is the security system located on a 2002 gmc safari awd?

On a 2002 GMC Safari AWD, the security system is typically integrated into the vehicle's engine control module (ECM) and may also involve the body control module (BCM). The main components of the security system, such as the ignition lock cylinder and the alarm system, are located within the vehicle's dashboard and under the steering column. If the vehicle is equipped with an aftermarket alarm system, the location may vary depending on the specific installation. For detailed troubleshooting or modifications, consulting the vehicle's service manual is recommended.
