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.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information. For further information, refer to “Privacy Practices” and
“Uconnect CyberSecurity” in “All About Uconnect Access”
in your Owner ’s Manual Radio Supplement and “Cyber-
security” in “Multimedia”.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improperly
installed, or damaged. A “gASCAP” message will be
displayed in the odometer. Tighten the gas cap until a
clicking
sound is heard. This is an indication that the gas
cap is properly tightened. Push the odometer reset button
to turn the message off. If the problem 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 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.
