2009 JEEP PATRIOT bulb

the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning light and the ABS light remain
on, the ABS and Electronic Brake Force Distribution
(EBD) systems are not functioning. Immediate repair to
the ABS is required.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABS
working properly. This self-check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may also experience the following when the brake
system goes into Anti-Lock mode:
•the ABS motor running (it may continue to run for a
short time after the stop)
•the clicking sound of solenoid valves
•brake pedal pulsations
•a slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.

persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the MIL. Resolving the problem will turn the MIL
light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recentlyserviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.

CAUTION! (Continued)
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you will not be using your vehicle for more than
21 days, you may want to take steps to preserve your
battery.
•Disengage the mini-fuse in the Power Distribution
Center labeled IOD (Ignition Off-Draw).
•Disconnect the negative cable from the battery.
