Operation
drive axle wheel slip is occurring during vehicle acceleration.
If drive axle wheel slippage is occurring, the Controller Relay
initiates action to reduce engine power and/or to selectively
apply rear brakes to transfer power from the slipping wheel to
the opposite wheel. This enables the vehicle to gain momentum
and move torque to road surfaces providing more traction. The
system instantly blinks a dash indicator to advise the driver that
wheel spin is occurring.
If wheel spin occurs at speeds above 25 mph (40 km/h), the dash
indicator blinks and, using its link to the engine control module,
the ATC reduces engine torque to a level suitable for the available
traction. The brakes are not applied, even slightly, at any speed
above 25 mph (40 km/h).
Both the AntilockBrake System and Automatic Traction Control
are features added to the basic air brake system and the loss
of either or both should in no way affect the basic brake system.
ABS and ATC require no changes in driving style and it is best not
to change your usual, careful driving habits. Other than during
initial start-up, when the TRAC CTRL indicator flashes and then
goes out, the ATC system should not be noticed until it’s needed.
Routine operation of the brakes and accelerator are unchanged.
ATC System Check
At ignition turn-on, the TRAC CTRL indicator will illuminate
steadily for 2.5 seconds and then turn off. If not, the system is
defective or inoperative.
ATC OFF ROAD or MUD/SNOW Switch
The optional ATC system comes equipped with one
of two switches that perform the same functions of
enabling and disabling the ATC system.
NOTE: Be sure to turn the ATC OFF ROAD or
MUD/SNOW switch off when you return to a firm
surface.
The function of this switch is to allow greater engine
power and more wheel spin. When operating on soft
road surfaces, place the OFF ROAD or MUD/SNOW
switch in the ENABLE position. The switch indicator
will flash slowly to indicate that this function has
been selected, and will flash rapidly whenever ATC is
operating to control excessive wheel spin.
