Brake System Warning; Light - Chevrolet 2015 Express Owner's Manual

Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is designed
to evaluate critical emission control
systems during normal driving. This
can take several days of routine
driving. If this has been done and
the vehicle still does not pass the
inspection for lack of OBD II system
readiness, your dealer can prepare
the vehicle for inspection.
Instruments and Controls

Brake System Warning

Light

The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
Metric
This light should come on briefly
when ignition key is turned to ON/
RUN. If it does not come on, have it
fixed so it will be ready to warn if
there is a problem.
