DIAGNOSIS SYSTEM
1. DESCRIPTION
When troubleshooting OBD II (On-Board Diagnostics)
vehicles, the intelligent tester (complying with SAE
J1987) must be connected to the DLC3 (Data Link
Connector 3) of the vehicle. Various data in the vehicle's
ECM (Engine Control Module) can be then read.
OBD II regulations require that the vehicle's on-board
computer illuminate the MIL (Malfunction Indicator
Lamp) on the instrument panel when the computer
detects a malfunction in:
(a) The emission control system components.
(b) The powertrain control components (which affect
vehicle emissions).
(c) The computer itself.
In addition, if the applicable DTCs (Diagnostic Trouble
Codes) prescribed by SAE J2012 are not recorded on 3
consecutive trips, the MIL turns off automatically but the
DTCs remain recorded in the ECM memory.
To check DTCs, connect the intelligent tester to the
DLC3. The tester displays DTCs, freeze frame data, and
a variety of the engine data. The DTCs and freeze frame
data can be erased with the tester (see page ES-39).
In order to enhance OBD function on vehicles and
develop the Off-Board diagnosis system, CAN
(Controller Area Network) communication is introduced
in this system. It minimizes the gap between technician
skills and vehicle technology. CAN is a network, which
uses a pair of data transmission lines, spanning multiple
computers and sensors. It allows high speed
communication between the systems and simplifies the
wire harness connection.
Since this system is equipped with the CAN
communication, connecting the CAN VIM (Vehicle
Interface Module) to the intelligent tester is necessary to
display any information from the ECM. (Also the
communication between the intelligent tester and the
ECM uses CAN communication signals.) When
confirming the DTCs and any data of the ECM, connect
the CAN VIM between the DLC3 and the intelligent
tester.
2. NORMAL MODE AND CHECK MODE
The diagnosis system operates in normal mode during
normal vehicle use. In normal mode, 2 trip detection
logic is used to ensure accurate detection of
malfunctions. Check mode is also available as an option
for technicians. In check mode, 1 trip detection logic is
used for simulating malfunction symptoms and
increasing the system's ability to detect malfunctions,
including intermittent problems (intelligent tester only)
(see page ES-42).

ES
3. 2 TRIP DETECTION LOGIC
When a malfunction is first detected, the malfunction is
temporarily stored in the ECM memory (1st trip). If the
same malfunction is detected during the next
subsequent drive cycle, the MIL is illuminated (2nd trip).
4. FREEZE FRAME DATA
Freeze frame data records the engine conditions (fuel
system, calculated engine load, engine coolant
temperature, fuel trim, engine speed, vehicle speed,
etc.) when malfunctions are detected. When
troubleshooting, freeze frame data can help determine if
the vehicle was moving or stationary, if the engine was
warmed up or not, if the air-fuel ratio was lean or rich,
and other data from the time the malfunction occurred.
5. DLC3 (Data Link Connector 3)
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.
If the result is not as specified, the DLC3 may have a
malfunction. Repair or replace the harness and
connector.
HINT:
The DLC3 is the interface prepared for reading various
data from the vehicle's ECM. After connecting the cable
of the intelligent tester to the CAN VIM, turn the ignition
switch ON 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.

DTC CHECK / CLEAR
NOTICE:
When the diagnosis system is changed from normal
mode to check mode or vice versa, all DTCs and freeze
frame data recorded in normal mode are erased. 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
the intelligent tester. The intelligent tester can display
current and pending DTCs.
• Some DTCs are not set if the ECM does not detect the
same malfunction again during a second consecutive
driving cycle. However, such malfunctions, detected on
only one occasion, are stored as pending DTCs.
1. CHECK DTC (Using intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES or PENDING CODES.
(e) Check 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 intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(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 intelligent tester)
(a) Perform either of the following operations.
(1) Disconnect the cable from the negative (-)
battery terminal for more than 1 minute.
(2) Remove the EFI and ETCS fuses from the
engine room relay block (located inside the
engine compartment) for more than 1 minute.

FREEZE FRAME DATA
1. DESCRIPTION
Freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature,
fuel trim, engine speed, vehicle speed, etc.) when a
malfunction is detected. When troubleshooting, it can
help determine if the vehicle was running or stopped, the
engine was warmed up or not, the air-fuel ratio was Lean
or Rich, and other data from the time the malfunction
occurred.
HINT:
If it is impossible to duplicate the problem even though a
DTC is detected, confirm the freeze frame data.
The ECM records engine conditions in the form of freeze
frame data every 0.5 seconds. Using the intelligent
tester, 5 separate sets of freeze frame data can be
checked.
– 3 data sets before the DTC was set.
– 1 data set when the DTC was set.
– 1 data set after the DTC was set.
These data sets can be used to simulate the condition
of the vehicle around the time of the occurrence of the
malfunction. The data may assist in identifying the
cause of the malfunction, and in judging whether it
was temporary or not.
