Chrysler 200: Electronic Brake Control System
Chrysler 200: Electronic Brake Control System
Your vehicle may be equipped with an optional advanced electronic brake control system that includes Anti-Lock Brake System (ABS), Traction Control System (TCS), Brake Assist System (BAS), and Electronic Stability Control (ESC). All systems work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESC.
- Anti-Lock Brake System (ABS)
- Traction Control System (TCS)
- Brake Assist System (BAS)
- Electronic Stability Control (ESC)
- ESC Activation/Malfunction Indicator Light And ESC Off Indicator Light
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control under adverse braking conditions. The system controls hydraulic brake pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and Operating” for further information.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) and engine power is reduced to provide enhanced acceleration and stability. A feature of the TCS system functions similar to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESC are in the “Partial Off” mode. Refer to “Electronic Stability Control (ESC)” in this section of this manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sensing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the Anti-Lock Brake System (ABS). Applying the brakes very quickly results in the best BAS assistance. To receive the benefit of the system, you must apply continuous braking pressure during the stopping sequence. Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.
WARNING!
• The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The BAS cannot prevent collisions, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning.
• The capabilities of a BAS-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 Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counteracting
the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path. ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC applies the
brake of the appropriate wheel to assist in counteracting
the oversteer or understeer condition
• 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.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents resulting from loss of vehicle control due to inappropriate driver input for the conditions. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESC equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
ESC Operating Modes
All ESC equipped vehicles can choose the following ESC operating modes:
ESC On
This is the normal operating mode for ESC. Whenever the vehicle is started the ESC system will be in this mode.
This mode should be used for almost all driving situations.
ESC should only be turned to “Partial Off” for specific reasons as noted below.
Partial ESC Mode
This mode is entered by momentarily pressing the “ESC Off” switch (located in the lower switch bank below the heater/air conditioning controls). When in “Partial Off” mode, the TCS portion of ESC, except for the limited slip feature described in the TCS section, has been disabled and the “ESC Activation/Malfunction Indicator Light” will be illuminated. All other stability features of ESC function normally, with the exception of engine power reduction. This mode is intended to be used if the vehicle is in deep snow, sand, or gravel conditions and more wheel spin than ESC would normally allow is required to gain traction.
ESC Off Switch
To turn ESC on again, momentarily press the “ESC Off” switch. This will restore the normal “ESC On” mode of operation.
WARNING!
In partial ESC mode, the engine power reduction
feature of ESC is disabled. Therefore, enhanced
vehicle stability offered by the ESC system is reduced.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC Off” switch. Once the situation
requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC on again by momentarily
pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.
ESC Activation/Malfunction Indicator Light And ESC Off Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will come on when the ignition switch is turned to the ON position. It should go out with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the engine running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (located 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 acceleration, 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 momentarily
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.
