IEIMobile Introduction
■ Locating people and vehicle on a map displayed on the mobile device
■ Finding someone or something. Person by skill (doctor), business directory, navigation, weather, trafc, room schedules, stolen phone, emergency calls
■ Location-based mobile advertising
■ Proximity-based notication (push or pull). Targeted advertising, buddy list, common prole matching (dating), automatic airport check-in, and payment
based upon proximity (EZ pass, toll watch)
■ Turn by turn navigation to any address
■ Receiving alerts, such as on sale notication or trafc jam alert
■ Requesting the nearest business or service, such as an ATM or a restaurant
■ Asset recovery combined with active RF to nd, for example, stolen vehicles or assets in containers
■ GPS data for operators to dispatch emergency personnel to the correct location
■ Resource tracking with dynamic distribution. Taxis, service people, rental equipment, doctors, eet scheduling

■ On-Board Diagnostics, or OBD, in an automotive context, is a generic term
referring to a vehicle's self-diagnostic and reporting capability. OBD systems give
the vehicle owner or a repair technician access to state-of-health information for
various vehicle sub-systems.
■ OBD-II is a standard that species the type of diagnostic connector and its pin-
out, the electrical signaling protocols available, and the messaging format.
■ Almost all of the automobiles produced today are required, by law, to provide an
interface for connecting a diagnostic test equipment.
On-Board Diagnostics (OBD-II)
OBD-II Cable
● Vehicle speed
● Engine RPM
● Total fuel used (litre since life time)
● High resolution vehicle distance
● Engine coolant temperature
● Vehicle ambient temperature
● Tachograph information
● Total engine hours (h)
● Fuel level (0–100 %)
● Fuel pressure
● Fuel system status
There are ve signalling protocols currently in use with the OBD-II interface. Any given vehicle will likely only implement one of the
protocols.
■ SAE J1850 PWM (pulse-width modulation - 41.6 kB/sec, standard of the Ford Motor Company)
■ SAE J1850 VPW (variable pulse width - 10.4/41.6 kB/sec, standard of General Motors)
■ ISO 9141-2. K-line and L-line. This protocol has an asynchronous serial data rate of 10.4 kBaud. It is primarily used in Chrysler, European,
and Asian vehicles.
■ ISO 14230 KWP2000 (Keyword Protocol 2000)
■ ISO 15765 CAN (250 kBit/s or 500 kBit/s). The CAN protocol is a popular standard outside of the US automotive industry and is making
signicant in-roads into the OBD-II market share. By 2008, all vehicles sold in the US will be required to implement CAN, thus eliminating
the ambiguity of the existing ve signalling protocols.
OBD-II provides access to numerous data from the engine control unit (ECU) and offers a valuable source of information when
troubleshooting problems inside a vehicle. The SAE J1979 standard denes a method for requesting various diagnostic data and a list of
standard parameters that might be available from the ECU. Following is a list of vehicle diagnostic information you can read from OBD-II. It
also shows a sample screen shot from IEIMobile Automotive PC.
● DTC (Diagnostic Trouble Code)
● Calculated engine load
● Intake air temperature
● Throttle position
● Accelerator pedal position (0–100 %)
● Axle weight (kg)
● Oxygen sensors and status
● Clutch switch (on/off)
● Brake switch (on/off)
● Cruise control (on/off)
● PTO (Status/Mode)
