2012 DODGE JOURNEY brake sensor

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering and under-steering the vehicle by
applying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of over-steer or under-steer.
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started the system will be in this mode. This
mode should be used for most driving situations. ESC
should only be turned to “Partial Off” for specific reasons
as noted. Refer to “Partial Off” for additional informa-
tion.
Partial Off
The “ESC OFF” button is located in the switch bank
above the climate control. To enter the “Partial Off”
mode, momentarily press the “ESC OFF” button and the
“ESC Activation/Malfunction Indicator Light” will illu-
minate. To turn the ESC on again, momentarily press the

STARTING AND OPERATING 405

The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
NOTE:
•The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer. TSC activates automatically once
the excessively swaying trailer is recognized. When TSC
is functioning, the “ESC Activation/Malfunction Indica-
tor Light” will flash, the engine power will be reduced,
and you will feel the brake being applied to individual
wheels in an attempt to stop the trailer from swaying.
NOTE: The TSC is disabled when the ESC system is in
the “Partial Off” mode.5
