Electronic Brake Control System - Chrysler Journey User Manual

The system controls hydraulic brake pressure
to prevent wheel lock-up to help avoid skidding
on slippery surfaces during braking. Refer to
"Anti-Lock Brake System (ABS)" under "Elec-
tronic Brake Control System" in this section for
more information.
WARNING!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. Only a safe, atten-
tive, and skillful driver can prevent accidents.
The capabilities of an ABS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
ELECTRONIC BRAKE CONTROL
SYSTEM
Your vehicle is equipped with an advanced
electronic brake control system commonly re-
176
ferred to as ESP. This system includes Anti-
Lock Brake System (ABS), Brake Assist System
(BAS), Traction Control System (TCS), Elec-
tronic Roll Mitigation (ERM), Electronic Stability
Program (ESP), and on some models, Hill Start
Assist (HSA). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically "pumps" the brakes dur-
ing severe braking conditions to prevent wheel
lock-up.
When the vehicle is driven over 7 mph
(11 km/h), you may also hear a slight clicking
sound as well as some related motor noises.
These noises are the system performing its self
check cycle to ensure that the ABS is working
properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph
(11 km/h).
ABS is activated during braking under certain
road or stopping conditions. ABS-inducing con-
ditions can include ice, snow, gravel, bumps,
railroad tracks, loose debris, or panic stops.
You also may experience the following when
the brake system goes into Anti-Lock:
• The ABS motor running (it may continue to
run for a short time after the stop),
• The clicking sound of solenoid valves,
• Brake pedal pulsations, and
• A slight drop or fall away of the brake pedal
at the end of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic
equipment that may be susceptible to inter-
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss
of anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
