Warning Chimes

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).

The warning chimes are designed to provide the driver with an audible warning that acts as a supplemental alert. The only deviation from this strategy is the air bag warning chime which is used to alert the driver that the primary alerting system (warning indicator) does not operate. The instrument cluster controls all warning chimes based on messages received from external modules. The purpose of the chime function is to draw the driver's attention to the instrument cluster or message center to view an informational indicator, warning indicator, a warning message, or simply to remind the driver of something such as a key left in the ignition or headlamps left on.

The warning device system consists of the following:

Instrument cluster
Safety belt switch (part of the safety belt buckle)
Key-in-ignition switch (part of the ignition switch)
Door ajar switch
Liftgate ajar switch
Liftgate glass ajar switch
SJB

The following chimes are controlled by the instrument cluster:

Air bag
Door and liftgate/glass ajar
Overspeed warning (gulf coast countries only)
Headlamps on
