2013 Ram C/V brake sensor

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational.Automatic Transmission vehicles
The BSM system sensors operate when the vehicle is in
any forward gear or REVERSE and enters stand-by mode
when the vehicle is in PARK.
Manual Transmission vehicles
The BSM system sensors operate when the vehicle is in
any gear and enters stand-by mode when the Park Brake
is engaged, the vehicle is not in REVERSE, and the
vehicle is stationary.
The BSM detection zone covers approximately one lane
on both sides of the vehicle (12 ft or 3.8 m). The zone
starts at the outside rear view mirror and extends ap-
proximately 23 ft (7 m) to the rear of the vehicle. The BSM
system monitors the detection zones on both sides of the
vehicle when the vehicle speed reaches approximately
6 mph (10 km/h) or higher and will alert the driver of
vehicles in these areas.

Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) enhances direc-
tional 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 matchthe intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent accidents

Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion. When TSC is functioning, the “ESC Activation/Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” mode.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
