NOTE
Tractors/Trucks and trailers built af-
ter 3/1/01 must be able to turn on an
In-Cab Trailer ABS Warning Lamp
(per U.S. FMVSS121). The indus-
try chose Power Line Communica-
tion (PLC) as the standard method to
turn it on. See Operating the Brake
System on page 4-21 for more in-
formation. On trailers built prior to
3/1/01 verify trailer ABS system sta-
tus via the required external warning
lamp mounted on the trailer. The in-
dicator lamp on the trailer should be
yellow and identified with the letters
“ABS”.

differential switch is ON thus locking
the inter-axle differential. This powers
the forward rear and the rear rear
differentials equally. When the switch
is turned off (inter-axle differential

to flow to any of the 4 drive tires based
on the differential effect (mostly to the
forward rear differential). This feature
is standard on all tandem axles.
