READINESS MONITOR DRIVE PATTERN
1. PURPOSE OF THE READINESS TESTS

The On±Board Diagnostic (OBD II) system is designed to monitor the performance of emission±re-
lated components and report any detected abnormalities in the form of Diagnostic Trouble Codes
(DTCs). Since the various components need to be monitored during different driving conditions, the
OBD II system is designed to run separate monitoring programs called Readiness Monitors. Many
state Inspection and Maintenance (I/M) programs require that vehicles complete their Readiness Mon-
itors prior to beginning an emission test.

The current status of the Readiness Monitors can be seen by using the hand±held tester with version
9.0 software (or newer), or a generic OBD II Scan tool.

To view the Readiness Monitor status using the hand±held tester, select ºMonitor Statusº from the En-
hanced OBD II Menu.

A status of ºcompleteº indicates that the necessary conditions have been met to run the performance
tests for the related Readiness Monitor.

The Readiness Monitor will be reset to ºincompleteº if:

ECM has lost power (battery or fuse).

DTCs have been cleared.

The conditions for running the Readiness Monitor have not been met.

In the event that any Readiness Monitor shows ºincomplete,º follow the appropriate Readiness Monitor
Drive Pattern to activate the monitor and change the readiness status to ºcomplete.º
CAUTION:
Strictly observe the posted speed limits, traffic laws, and road conditions when performing these
drive patterns.
NOTICE:
These drive patterns represent the fastest method to satisfy all necessary conditions which allow
the specific readiness monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other fac-
tors) the drive pattern can be resumed, and in most cases, the readiness monitor will still set to ºcom-
pleteº.
To ensure rapid completion of readiness monitors, avoid sudden changes in vehicle load and speed
(driving up and down hills and/or sudden acceleration).

ACTIVE TEST
Performing the ACTIVE TEST using the hand±held tester allows the meters, indicators and so on to operate
without part removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to shorten
labor time.
It is possible to display the DATA LIST on the hand±held tester during the ACTIVE TEST.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) From the display on the tester, perform the ºACTIVE TESTº.

SYSTEM DESCRIPTION
1. COMPACT DISC PLAYER
Compact Disc (hereafter called ºCDº) Players use a laser beam pick±up to read the digital signals recorded
on the CD and reproduce analog signals of the music, etc. 4.7 in. (12 cm) and 3.2 in. (8 cm) discs are available
for the CD player.
HINT:
Never disassemble or apply oil to any part of the player unit. Do not insert any object other than a disc, into
the CD player.
NOTICE:
CD players use an invisible laser beam which could cause hazardous radiation exposure. Be sure
to operate the player correctly as instructed.
2. MAINTENANCE
Tape Player / Head Cleaning:
(a) Raise the cassette door with your finger.
Using a pencil or similar object, push in the guide.
(b) Using a cleaning pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.
3. MAINTENANCE
CD Player / Disc Cleaning:
If the disc gets dirty, clean the disc by wiping the surface from
the center to outside in a radial directions with a soft cloth.
NOTICE:
Do not use a conventional record cleaner or anti±static pre-
servative.

PRECAUTION
HINT:
All DTCs retained in the ECM will be erased when the negative
(±) terminal cable is removed from the battery.
If necessary, read the DTC before removing the negative (±)
terminal cable from the battery.
1. BEFORE WORKING ON FUEL SYSTEM,
DISCON-
NECT CABLE FROM NEGATIVE (±) BATTERY TERMI-
NAL
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) To prevent engine misfire, these precautions should be
taken.
(1) Check the battery terminals are proper connected.
(2) After repair, check that the ignition coil terminals
and all other ignition system lines are reconnected
securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Observe the following when handling the air fuel ratio
sensors and oxygen sensor.
(1) Do not drop the sensor or hit it against another ob-
ject.
(2) The sensor should be free from any contact with wa-
ter.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Removal of the engine oil dipstick, oil filler cap, PCV hose,
may break the engine.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head may result in air suction and break the engine.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, first
disconnect the power by turning the ignition switch off or
disconnecting the negative (±) terminal cable from the
battery.
HINT:
Be sure to check DTCs before disconnecting the negative (±)
terminal cable from the battery.

(j) Check that there is any fuel leak after maintenance any-
where on the fuel system.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Turn the ignition switch ON and push the hand±held
tester main switch ON.
NOTICE:
Do not start the engine.
(3) Enter the following menus: DIAGNOSIS / EN-
HANCED OBDII / ACTIVE TEST / FUEL PUMP /
SPD.
(4) Please refer to the hand±held tester operator's
manual for further details.
(5) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state,
check to see that there are no leaks from any part
of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(6) Turn the ignition switch OFF.
(7) Disconnect the hand±held tester and CAN VIM

CAUTION:

Check that the battery cables are connected to the
correct terminals.

Disconnect the battery cables when the battery is giv-
en a quick charge.

Do not perform tests with a high voltage insulation re-
sistance tester.

Never disconnect the battery while the engine is run-
ning.
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible) and check the charging system.
2. Except Maintenance±Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 to 1.29 at 20°C (68°F)
If the specific gravity is less than the specification, charge the
battery.
3. Maintenance±Free Battery:
CHECK BATTERY VOLTAGE
(a) In the case that 20 minutes have not passe4d after stop-
ping the engine, turn on the ignition switch and the electri-
cal system (headlight, blower motor, rear defogger, etc.)
for 60 seconds before removing the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
