Illuminates during normal operating
conditions to indicate a problem with the
Trailer ABS System. This should be
checked by an authorized dealer 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 Lamp (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 required external warning lamp
mounted on the trailer. The indicator lamp
on the trailer should be yellow and identified
with the letters ABS.
