Alarm Event PIDs
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The SJB has PIDs available that show what caused the last alarm events. The 4 SJB alarm event PIDs are AL_EVT1 through 4. The cause for the most recent alarm activation is always listed in the first alarm event PID. These PIDs display what caused the alarm to activate and can be a very useful tool when trying to identify the cause of a false alarm activation.
