TCS function is part of Electronic Stability Program (ESP). It is
intended to enhance the stability & acceleration when wheel spin is
occurred. It monitors the speed sensor input on each wheels and
uses brakes or engine torque control to provide optimum tractive
force on driven wheels during acceleration in slippery surfaces. A
feature of TCS, Braking Traction Control (BTC), functions similar to
the locking differential and controls the wheel spin across driven
axle. If more than one wheel on driven axle is spinning faster than
the other, the system will apply the brake on spinning wheel. This
will allow more engine torque to be transferred to the wheel that is
not spinning. BTC remains enabled even in ESP off mode. To
effectively use the BTC system the driver should gradually
accelerate in a situation where 'wheel slip' is occurring. This will
allow the sensors to determine the need to apply the brake to the
slipping wheels
The ESP system has two available operating modes in 2H & 4H
modes. The system has one operating mode in 4L mode.
22HH aanndd 44HH MMooddeess::
EESSPP OONN
This is the normal operating mode for ESP in 2H & 4H range.
EESSPP OOFFFF
This mode is entered by momentarily pushing the
ESP OFF switch. When in “ESP OFF” mode, the TCS
portion of ESP (except for Braking Traction Control
described in TCS section) gets disabled and the “ESP OFF” indicator
light turns ON. This mode is intended to be used if the vehicle is in
deep snow, sand and gravel in order to gain the traction. In ESP
OFF mode, the engine torque reduction and stability features are
disabled. Therefore enhanced vehicle stability offered by ESP is
unavailable until the vehicle speed reaches the approximate speed
of 55 kmph. For speeds at or exceeding approximately 55 kmph,
the ESP goes into normal “ESP On” mode automatically in order to
maintain the vehicle stability. To turn the ESP on again, momentarily
