Using the Brake System<br />
Trailer ABS Warning Lamp<br />
Trucks, tractors, and trailers built on and after March 1, 2001<br />
are equipped with power line communication (PLC) per U.S.<br />
FMVSS 121, including a trailer ABS warning lamp in the cab.<br />
ABS<br />
CAUTION: If the trailer ABS warning lamp does<br />
not illuminate when the ignition is first turned<br />
on, there is a problem with the bulb or wiring.<br />
The driver should have this checked as soon as<br />
possible.<br />
NOTE: A successsful warning lamp illumination and<br />
bulb check at ignition on does not indicate that the<br />
trailer you may be connected to has trailer ABS. You<br />
should personally inspect every trailer to determine<br />
its braking system.<br />
Operating Instructions<br />
A trailer ABS warning lamp will illuminate for a bulb check<br />
when the ignition switch is first turned on - whether or not a<br />
trailer is connected to the vehicle. If the bulb check is satisfactory,<br />
the lamp will next do either of the following:<br />
1. If no trailer is connected, or if a non-ABS-equipped trailer<br />
is connected, the trailer ABS lamp will go off after a few<br />
seconds.<br />
NOTE: A “properly connected” ABS-equipped trailer<br />
is<br />
• a trailer with PLC hooked up to the J560 connector.<br />
• a trailer without PLC that is hooked up to an<br />
optional ISO 3731 connector.<br />
NOTE: For doubles or triples: PLC does not distinguish<br />
between trailers. An ABS problem in any<br />
trailer will activate the trailer ABS warning lamp.<br />
2. If an ABS-equipped trailer is properly connected, the<br />
trailer ABS warning lamp will remain illuminated for a few<br />
more seconds while the trailer ABS is tested.<br />
• If no trailer ABS problems are detected, the<br />
lamp will go off.<br />
