maintenance reset NISSAN FRONTIER 2001 D22 / 1.G Owners Manual

Due to legal requirements in some states
and Canadian provinces, your vehicle may
be required to be in the ready condition for
an Inspection/Maintenance (I/M) test of the
emission control system.
The vehicle is set to the ready condition
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a not ready condi-
tion. Before taking the I/M test, drive the
vehicle through the following pattern to set
the vehicle to the ready condition.
WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic
conditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C.
Allow the engine to idle until the gauge
needle points between the C and H (nor-
mal operating temperature).2. Accelerate the vehicle to 55 mph (88
km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 6 seconds.
3. Quickly depress the accelerator pedal for
a moment, then drive the vehicle at a
speed of 53 to 60 mph (85 to 97 km/h) for
at least 5 minutes.

mode is acceptable between steps. Do not

pleted. If you cannot or do not want toperform the driving pattern, an authorized
NISSAN dealer can conduct it for you.
Dynamometer testing for Inspection/
Maintenance (I/M) test (US only)
Due to legal requirements in some
states/areas, your vehicle may be tested for
emissions on a dynamometer. The transfer
control lever (if so equipped) MUST be in
the 2H position for I/M testing on a two
wheel dynamometer.
WARNING
cIf the transfer control lever is not in
the 2H position during the dyna-
mometer I/M testing, the vehicle
could come off the dynamometer
and cause serious personal injury
and/or body damage to the vehicle.
cSerious damage will occur to the
4WD system if the transfer control
lever is not in the 2H position
