BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when engine troubleshooting.
NOTICE:
Carry out this check with the engine stopped and ignition
switch off.

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).

5. DLC3 (Data Link Connector 3)
(a) The vehicle's ECM uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, any other switches
or the doors.
HINT:
The DLC3 is the interface prepared for reading
various data from the vehicle's ECM. After
connecting the cable of an intelligent tester, turn the
ignition switch to the ON position and turn the tester
ON.
• If a communication failure message is displayed
on the tester screen (on the tester: UNABLE TO
CONNECT TO VEHICLE), a problem exists in
either the vehicle or tester. In order to identify the
location of the problem, connect the tester to
another vehicle.
• If communication is normal: Inspect the DLC3 on
the original vehicle.
• If communication is impossible: The problem is
probably in the tester itself. Consult the Service
Department listed in the instruction manual.
6. BATTERY VOLTAGE
Battery Voltage:
11 to 14 V
If the voltage is below 11 V, recharge the battery before
proceeding to the next step.
7. MIL (Malfunction Indicator Lamp)
(a) The MIL is illuminated when the ignition switch is
first turned to the ON position (the engine is not
running).

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.

CHECK MODE PROCEDURE
HINT:
Intelligent tester only:
Compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
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 off or
turned to the ACC position from the ON position while in
check mode.
Before changing modes, always check and make a note
of any DTCs and freeze frame data.
1. CHECK MODE PROCEDURE (Using an intelligent
tester)
(a) Check and ensure the following conditions:
(1) Battery voltage 12 V or more
(2) Throttle valve fully closed
(3) The shift lever in the P or N position
(4) A/C switched OFF
(b) Turn the ignition switch off.
(c) Connect an intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn the tester ON.
(f) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / CHECK MODE.
(g) Switch the ECM from normal mode to check mode.
(h) Make sure that the MIL flashes as shown in the
illustration.
(i) Start the engine.
(j) Make sure that the MIL goes off.
(k) Simulate the conditions of the malfunction described
by the customer.
(l) Check for DTCs and freeze frame data using the
tester.
