On-Board Diagnostics Overview - Novatel RTT2211 User Manual

On-Board Diagnostics Overview

The Novatel Wireless M2M MT 3060 connects to a vehicle's On-Board Diagnostics (OBDII)
port and monitors the OBDII system using communication protocols. An On-Board Diagnostics
(OBD) system controls engine functions and serves as the diagnostic control network of the
vehicle. All cars built and sold in the United States since 1996 require the newer OBDII system.
You can configure the MT 3060 to provide notification messages based on events triggered
by:
Accelerometer change
l
Check engine light (MIL alert)
l
Engine RPM
l
GPS information
l
Idle time
l
Low fuel
l
Trip Odometer (trip distance)
l
Vehicle battery voltage (low battery warning)
l
Vehicle Identification Number (VIN)
l
Vehicle speed
l
Other events monitored by the OBDII system
l
Some vehicles are not compatible with the MT 3060. If a vehicle is not compatible
with the required MT 3060 parameters, then functionality may be limited,
problematic, or unavailable.
The 1979 Society of Automobile Engineers (SAE) standard defines the method for requesting
diagnostics data and provides a list of standard parameters from the engine control unit.
Since the vehicle manufacturer is responsible for complying with the SAE standard, Novatel
Wireless M2M cannot guarantee that the MT 3060 will perform with every vehicle.
