•
When the ignition key is turned to the on
position, the trailer ABS telltale lamp
illuminates momentarily, then deactivates.
•
If the telltale illuminates momentarily during
vehicle operation, then shuts off, a fault was
detected and corrected.
•
If the telltale illuminates and stays on during
vehicle operation, there is a fault with the
trailer ABS. Repair the trailer ABS system
immediately to ensure full antilock braking
capability.
The trailer ABS telltale will not illuminate if an
incompatible trailer is connected to the tractor.
Automatic Traction Control
Electric vehicles with ABS are equipped with
automatic traction control (ATC). On these vehicles,
the ATC system automatically limits wheel spin
during reduced-traction situations. If the vehicle
comes to a stop in soft soil or sand, it may be
necessary to back up prior to attempting forward
movement.
When the ATC system is in normal mode, it applies
gentle braking to the spinning wheel to feed power to
the wheel(s) with better traction. If both wheels are
spinning, the system signals the motor to reduce
power.
If the system detects wheel spin, the wheel spin
telltale, shown in
11.15, flashes and an alert is
shown on the driver display.
Pressing the ATC SPIN switch, shown in Fig. 11.16,
deactivates ATC and allows drive wheel spin. When
ATC is off, an ATC deactivated telltale, as shown in
Fig. 11.17, appears on the driver display. Pressing
the switch again, or cycling the keyswitch, cycles the
system back to normal operation.
NOTICE
The ATC spin feature is intended to be used
under specific slippery conditions that require
momentary increased wheel spin. Using this
option for an extended period of time may
damage the vehicle’s brake system.
Brake and Traction Telltales
Telltales and messages appear on the driver display.
The positions of the telltales vary, but most use
standard symbols.
The colors of telltales indicate the hazard level as
follows: red (warning), amber (caution), green
(normal function), blue (active status), grey (passive
status), white (informational).
The colors of messages indicate the hazard level as
follows: red (warning), amber (caution), grey
(informational).
Telltales for braking and traction related features are
listed in
Table 11.1. Every vehicle may not be
equipped with every feature.
