ECU DODGE VIPER 2017 VX / 3.G Owner's Guide

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote cleaner
air, your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions and engine control systems.
When these systems are operating properly, your vehicle
will provide excellent performance and fuel economy, as
well as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light. It will also
store diagnostic codes and other information to assist your
service technician in making repairs. Although your ve-
hicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.
CAUTION!
Prolonged driving with the light on could cause fur-
ther damage to the emission control system. It could
also affect fuel economy and driveability. The vehicle
must be serviced before any state emissions tests can
be performed.If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•
ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.

WARNING!(Continued)
•Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Privacy Practices — If
Equipped With Uconnect 8.4 Radio” and “Uconnect Cy-
berSecurity” in “All About Uconnect Access” in your
Owner ’s Manual Radio Supplement and “Cybersecurity”
in “Understanding Your Instrument Panel”.
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 may notbe ready if your vehicle was recently
serviced, or recently had a dead battery or a battery replacement. 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 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 follow-
ing:
1. Cycle the ignition to the ON mode, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition to the ON mode, you will see the “Malfunction Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then return
to being fully illuminated until you cycle the ignition
OFF or start the engine. This means that your vehicle’s
OBD II system is not readyand you should notproceed
to the I/M station.

Master Cylinder — Brake Fluid Level Check
Check the fluid level in the master cylinder immediately if
the brake system warning light indicates system failure.
Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up to
the requirements described on the brake fluid reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
With disc brakes, fluid level can be expected to fall as the
brake pads wear. However, low fluid level may be caused
by a leak and a checkup may be needed.
Use only the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information. Use of a
brake fluid that may have a lower initial boiling point or
unidentified as to specification, may result in sudden brake
failure during hard prolonged braking.
WARNING!
•Use only manufacturer ’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a accident.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
