166 OPERATION
DANGER
Some trailers manufactured prior to the trailer ABS regulations may use the
center pin to power certain trailer auxiliary equipment. The possibility exists that
this auxiliary equipment may be unexpectedly activated by the truck or tractor
electrical system, resulting in personal injury or damage to equipment. Caution
must be used when connecting the trailer electrical connector to ensure that
power to the center pin will not unintentionally activate any trailer auxiliary
equipment.
Automatic Traction Control (ATC) (If Equipped)
W3001113
Automatic Traction Control (ATC) provides improved traction on slippery
surfaces by reducing wheel spin. The system operates automatically as
follows:
• If a drive wheel starts to spin, ATC applies air pressure to the brake of the
spinning wheel. Doing this transfers engine torque to the wheels that have
better traction.
• If all drive wheels are spinning, ATC limits engine torque which, in turn,
reduces wheel spin to provide improved traction.
When ATC automatically becomes active, the ATC indicator lamp turns on to
alert the operator. The lamp turns off when the wheel(s) stops spinning.
