The impact sensors are located within the front bum-
per area.
The EPPM monitors the readiness of the electronic
parts of the Active Hood system whenever the ignition
switch is in the START or ON/RUN position. If the key
is in the LOCK position, in the ACC position, or not in
the ignition, the Active Hood system is not on and the
Active Hood will not deploy.
The EPPM contains a backup power supply system that
may deploy the actuators even if the battery loses
power or it becomes disconnected prior to deploy-
ment.
Service Active Hood System
If the EPPM has deployed the Active Hood, or if it
detects a malfunction in any part of the system, it turns
on the Air Bag Warning Light and it will display the
“SERVICE ACTIVE HOOD” message in the Electronic
Vehicle Information Center (EVIC), for versions/
markets, where provided. A single chime will sound if
the Air Bag Warning Light comes on again after initial
startup. It also includes diagnostics that will illuminate
the Air Bag Warning Light if a malfunction is noted that
could affect the Active Hood system. The diagnostics
also record the nature of the malfunction. If the Air Bag
Warning Light is illuminated, or if “SERVICE ACTIVE
HOOD” appears in the EVIC, see your authorized
dealer.
In the event of an Active Hood deployment, the vehicle
should be serviced by an authorized dealer. The hood
hinges must be serviced and the actuator assemblies
replaced to restore system functionality.
Following an Active Hood deployment, the hood posi-
tion can be temporarily reset by pushing down at the
rear edge over the hood hinges as the internal pressure
of each actuator is relieved. The temporary hood reset
position is intended to improve forward driving visibil-
ity over the hood until the vehicle can be serviced. The
temporary hood reset position will leave the hood
approximately 5 mm above the fender surface.
