Jeep Wrangler: GETTING TO KNOW YOUR INSTRUMENT PANEL / ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission 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 (MIL). It will also store diagnostic
codes and other information to assist your
service technician in making repairs. Although your vehicle will usually be
drivable and not
need towing, see an authorized dealer for
service as soon as possible.
CAUTION!
- Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
- If the MIL is flashing while the vehicle is
running, 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 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 access this information to assist with
the diagnosis and service of your vehicle and
emissions system.
WARNING!
- ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
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.
