To ensure your AAMP P-BUA-EXPRESS backup alarm is functioning correctly after installation on your Express, follow these simple steps: First, confirm that the wiring harness and alarm unit are installed according to the AAMP instructions. Then, with everything connected securely, turn on your vehicle's ignition to power the electrical system. Next, shift your Chevrolet Express into reverse gear; this action activates the backup alarm system. Now, move to a safe position behind the vehicle and listen carefully for the audible alert. If you hear the distinct sound of the backup alarm, it confirms a successful installation. Should the alarm not sound, thoroughly re-examine all connections, wiring, and installation procedures to eliminate any potential issues. If problems continue to persist, and the alarm remains silent, reach out to AAMP Commercial for expert assistance via their provided contact information.
