Trailer ABS Warning Lamp
Trucks, tractors, and trailers built on and after March 1, 2001 are
equipped with power line communication (PLC) per U.S. FMVSS 121,
including a trailer ABS warning lamp in the cab (see Item 15 on page

A trailer ABS warning lamp will illuminate for a bulb check when the
ignition switch is first turned on - whether or not a trailer is connected
CAUTION: If the truck/tractor ABS warning lamp does
not illuminate when the ignition is first turned on, there
is a problem with the bulb or wiring. The driver should
have this checked as soon as possible.
CAUTION: If the trailer ABS warning lamp does not illu-
minate when the ignition is first turned on, there is a
problem with the bulb or wiring. The driver should have

NOTE: A successsful warning lamp illumination and bulb
check at ignition on does not
indicate that the trailer you may
be connected to has trailer ABS. You should personally
inspect every trailer to determine its braking system.
