NOTE
Tractors/Trucks and trailers built after
03/01/2001 must be able to turn on an
In-Cab Trailer ABS Warning Lamp (per
U.S. FMVSS121). The industry chose

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 lamp mounted
on the trailer. The indicator lamp on
the trailer should be yellow and identi-
fied with the letters ABS.

Illuminates when the inter-axle differential
switch is ON thus locking the inter-axle

When the switch is turned off (inter-axle
differential unlocked) the engine power is
allowed to flow to any of the four drive tires
based on the differential effect (mostly to
the forward rear differential). (This feature
is standard on all tandem axles).
