Anti-Lock Brake System Warning Light; Trailer Anti-Lock Brake System Warning Light - Chevrolet T-Series Owner's Manual

Anti-Lock Brake System
Warning Light
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the BRAKE
or LOW AIR warning light is not on, you still
have brakes, but you do not have the anti-lock
brake feature. If the BRAKE and/or LOW AIR
warning light is on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. See Brake System Warning Light on
page 107 and Anti-Lock Brake System (ABS) on
page 136 for more information.
The anti-lock brake system warning light should
come on briefly when you turn the ignition key to
ON. If the light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
This light will come on
briefly when you start
your engine, then
it will turn off. This
is normal.
Trailer Anti-Lock Brake System
Warning Light
When this light comes on and stays on, it means
there is something wrong in the trailer anti-lock
brake system. Have the system repaired
immediately.
If an anti-lock brake system equipped trailer is not
connected, this light is not functional.
If your vehicle is
connected to a trailer
with anti-lock brakes,
this light should
come on briefly, as a
check, when you turn on
the ignition.
