NOTE
If the Trailer ABS Warning
Lamp
does not turn on during
the power-on self test, there
may be a problem with the light
or wiring. You should have this
checked as soon as possible.
NOTE
Tractors/Trucks and trailers built after
03/01/2001
must be able to turn on an
In-Cab Trailer ABS Warning Light (per
U.S. FMVSS121). The industry chose
Power Line Communication (PLC) as
the standard method to turn it on. On
trailers built prior to 03/01/2001 verify
trailer ABS system status via the re-
quired external warning light mounted
on the trailer. The indicator light on the
trailer should be yellow and identified
with the letters ABS.
NOTE
The Trailer ABS Warning Lamp will not
turn
on when connected to trailers with
ABS (but without PLC) powered
through
the primary 7-way trailer light
line. Use the lamp on the driver's side
of the trailer to identify trailer ABS
problems.
NOTE
For doubles or triples, the lamp does
not
distinguish between trailers. An
ABS problem in any of the trailers will
activate the Trailer ABS Warning
Lamp.
Axle, Stability Control (Option)
Calculates the driver’s intended path of
travel from wheel speed and steering angle
sensors, then compares calculations to the
actual direction of travel. The system uses
individual wheel brakes to re-adjust the
path of the vehicle.
•
The Stability Control Icon (ESC or
Electronic Stability Control)
illuminates during the Bulb Check
when the ignition is turned ON. It
turns off after a few seconds if no
system problems are detected. If a
problem is detected, the ESC
Warning lamp will turn on and stay
on.
• Illuminates when the ESC system
is regulating individual wheel
brakes to correct the vehicle’s
direction of travel. (Refer to
Advanced ABS with Stability
Control for more information.)
