Jeep Wrangler JK 2018 Owner's Manual page 219

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" or "Full Off" modes.
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.
Hill Descent Control (HDC) — If Equipped
HDC is only intended for low speed off-road driving. HDC
maintains vehicle speed while descending hills in off-road
driving conditions by applying the brakes when necessary.
The symbol indicates the status of the Hill De-
scent Control (HDC) feature. The lamp will be on
solid when HDC is armed. HDC can only be
armed when the transfer case is in the "4WD
LOW" position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while attempting
to use the HDC feature, the HDC indicator light will flash
on/off.
When enabled, HDC senses the terrain and activates when
the vehicle is descending a hill. HDC speed may be
adjusted by the driver to suit the driving conditions. The
speed corresponds to the transmission gear selected.
