READINESS MONITOR DRIVE
PAT T E R N
1. PURPOSE OF READINESS TESTS
• The On-Board Diagnostic (OBD II) system is
designed to monitor the performance of emission-
related components, and indicate any detected
abnormalities with DTCs (Diagnostic Trouble Codes).
Since various components need to be monitored in
different driving conditions, the OBD II system is
designed to run separate monitoring programs called
Readiness Monitors.
• The intelligent tester's software must be version 9.0 or
newer to view the Readiness Monitor status. To view
the status, select the following menu items:
DIAGNOSIS / ENHANCED OBD II / MONITOR INFO
/ MONITOR STATUS.
• When the Readiness Monitor status reads COMPL
(complete), the necessary conditions have been met
for running the performance tests for that Readiness
Monitor.
• A generic OBD II scan tool can also be used to view
the Readiness Monitor status.
HINT:
Many Inspection and Maintenance (I/M) programs
require a vehicle's Readiness Monitor status to show
COMPL before beginning emission tests.
The Readiness Monitor will be reset to INCMPL
(incomplete) if:
• The ECM has lost battery power or broken a fuse.
• DTCs have been cleared.
• The conditions for running the Readiness Monitor
have not been met.
If the Readiness Monitor status shows INCMPL, follow
the appropriate Readiness Monitor Drive Pattern to
change the status to COMPL.
CAUTION:
Strictly observe posted speed limits, traffic laws, and
road conditions when performing these drive
patterns.
NOTICE:
These drive patterns represent the fastest method of
satisfying all conditions necessary to achieve
complete status for each specific Readiness
Monitor.
In the event of a drive pattern being interrupted
(possibly due to factors such as traffic conditions),
the drive pattern can be resumed. In most cases, the
Readiness Monitor will still achieve complete status
upon completion of the drive pattern.
To ensure completion of the Readiness Monitors,
avoid sudden changes in vehicle load and speed
(driving up and down hills and/or sudden
acceleration).

DTC CHECK / CLEAR
NOTICE:
All the stored DTCs and freeze frame data are erased if:
1) the ECM is changed from normal mode to check mode
or vice versa; or 2) the ignition switch is turned from ON
to ACC or off while in check mode.
Before changing modes, always check and make a note
of any DTCs and freeze frame data.
HINT:
• DTCs which are stored in the ECM can be displayed on an
intelligent tester. An intelligent tester can display current
and pending DTCs.
• Some DTCs are not set if the ECM does not detect the
same malfunction again during the second consecutive
driving cycle. However, such malfunctions, detected on
only one occasion, are stored as pending DTCs.
1. CHECK DTC (Using an intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES.
(e) Check for the DTC(s) and freeze frame data, and
then write them down.
(f) Check the details of the DTC(s) (See page ES-56).
2. CLEAR DTC (Using the intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CLEAR CODES.
(e) Press the YES button.
3. CLEAR DTC (Without using an intelligent tester)
(a) Perform either one of the following operations:
(1) Disconnect the negative battery cable for more
than 1 minute.
(2) Remove the EFI No. 1 and ETCS fuses from the
Relay Block (R/B) located inside the engine
compartment for more than 1 minute.

ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte level.
(1) If the electrolyte level is low, replace the battery
(or add distilled water) and check the charging
system.
2. CHECK BATTERY SPECIFIC GRAVITY
(a) Check the color of the hydrometer.
Result
3. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since the vehicle was
driven or since the engine was stopped, turn the
ignition switch to the ON position and turn on the
electrical systems (headlights, blower motor, rear
defogger, etc.) for 60 seconds. This will remove the
surface charge from the battery.
(b) Turn the ignition switch off and the electrical
systems off.
(c) Measure the battery voltage between the negative (-
) and positive (+) terminals of the battery.
Standard voltage:
12.5 to 12.9 V at 20
C (68F)
HINT:
If the voltage is below the specification, charge the
battery.
4. CHECK BATTERY TERMINAL
(a) Check that the battery terminals are not loose or
corroded.
If the terminals are corroded, clean them.
5. CHECK FUSES
(a) Measure the resistance of the ALT fuse, ALT-S fuse,
GAUGE fuse and GAUGE 1 fuse.
Standard resistance:
Below 1
If the result is not as specified, replace the fuses as
necessary.
6. CHECK V-RIBBED BELT
(a) Check the belt for wear, cracks or other signs of
damage.
If any of the following defects is found, replace the
V-ribbed belt.
• The belt is worn out, cracked, or the cords are
exposed.
• The cracks reach the cords in more than one
place.
• The belt has chunks missing from the ribs.
