SYMPTOM

The factory security system may sound on its own or the system may not set. The client may also notice that the horn
does not sound or the lights do not flash when setting the alarm (security system is not set).
POSSIBLE CAUSES

Excessive clearance in the hood latch causes the hood latch switch to indicate the hood is open when it is not.
CORRECTIVE ACTION

Replace the hood latch assembly.
