Body Control Module (PZM)

The body control module (PZM) controls all of the alarm functions. When the PZM detects an unauthorized entry, the PZM applies ground to the following components:
- The horn relays
- The park lamp relays
- The headlamp relays

The PZM applies ground once per second for approximately 3 minutes, or until a valid input to disarm the system is received by the PZM.
