BACKGROUND

The purpose of this document is to provide additional information on the inspection process of alternative fueled
vehicles equipped with On-Board  Diagnostic (OBD) systems. Specifically, this document provides additional
technical information and impacts on the OBD system monitoring capability when flexible fuel vehicles (FFVs)
are operated using alternative fuel.  Also, it will assist Inspection and Maintenance (I/M) Programs in
implementing OBD system checks and educating owners of FFVs.

Alternative fuel vehicles are vehicles that are designed to operate on fuels such as compressed natural gas
(CNG), liquid petroleum gas (LPG), ethanol-based and methanol-based fuels in lieu of or in conjunction with
traditional petroleum-based fuels (e.g. gasoline ordiesel fuel) and can be divided into three categories.
Dedicated alternate fuel vehicles operate solely on an alternative fuel. Bi-fuel vehicles can operate on two
different fuel types (e.g., a petroleum-based fuel and an alternative  fuel) but store the fuels in separate tanks
allowing manual switching between fuels. FFVs can also operate on two different fuel types but allow the fuels
to mix or blend in a single fuel tank.

For FFVs, the engine system typically monitors the fuel content in the fuel tank to determine the level of
alternative fuel versus petroleum-based fuel, and adjust the vehicle/engine calibrations accordingly. Currently,
ethanol has been the alternate fuel of choice for FFVs with fuel contents ranging from EO (0% ethanol, 100%
unleaded gasoline) up to E85 (85% ethanol, 10% unleaded gasoline) but this is subject to change due to
continued alternative energy research.

On-Board Diagnostics (OBD) systems have been implemented on light-duty vehicles and trucks equipped with
Otto-cycle, diesel-cycle and alternative fuel engines since the 1996 model year.  The OBD system monitors
many emission control and emission-related powertrain components and the vehicle must be operated under
specific conditions to enable this monitoring.  As a result, state programs that typically required inspection  of
tailpipe emissions are now  relying and implementing diagnostic checks of OBD systems  in lieu of tailpipe
emissions inspections.

For alternative fuel vehicles, there were earlier concerns during OBD implementation regarding OBD system
monitoring capability during alternative fuel operation.  These concerns necessitated additional OBD monitoring
flexibilities during alternative fuel operation to eliminate the potential of false illumination  of malfunction indicator
lamp (MIL, "check engine" or "service engine soon" light). Therefore, Federal OBD regulations in  40 CFR
86.1806-05 allowed  manufacturers of alternate fuel vehicles to request waivers from OBD monitoring during
alternate fuel operation until the 2004 model year (MY). In particular, FFVs are of greater concern since there is
no clear indication of a switch from a petroleum-based  fuel to an alternative fuel. As a result, the  OBD system
for FFVs may operate differently from other vehicles including revised OBD system capability and engine
calibration when the level of alternative fuel, specifically ethanol, is  increased.  This is further complicated if the
vehicle is operated for an extended period of time or solely on ethanol prior to a state inspection of the OBD
system.

This document attempts to  outline the universe of certified FFVs, clarify the OBD system capabilities of these
vehicles when operated on alternative fuel, and provide recommended procedures to enable proper OBD I/M
inspection of FFVs that may have a reduced level of OBD system capability during alternative fuel operation.

The U.S. EPA has coordinated with the automotive  industry to develop this list document.  The document is
separated by manufacturer and by ascending model year starting with MY1996, the first  year that full OBD
compliance was required, and ending with MY2007 (in  some cases MY2008 information  was provided and is
included, where available).  However, it should be noted that all MY2005 and beyond light-duty alternative fuel
vehicles are required to have full OBD monitoring capabilities during gasoline and alternative fuel  operation
since the OBD monitoring flexibilities during alternate fuel operation have been  removed. Therefore, MY2005
and beyond FFVs should be fully functional with any fuel type or blend.
