4. FREEZE FRAME DATA
(a) 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, freeze frame data can help
determine if the vehicle was running or stopped, 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.
(b) The intelligent tester records freeze frame data in 5
different instances: 1) 3 times before the DTC is set,
2) once when the DTC is set, and 3) once after the
DTC is set. These data can be used to simulate the
vehicle's condition around the time when the
malfunction occurred. The data may help find the
cause of the malfunction, or judge if the DTC is
being caused by a temporary malfunction or not.
5. DATA LINK CONNECTOR 3 (DLC3)
(a) The vehicle's ECM uses the ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
HINT:
*: Before measuring the resistance, leave the vehicle as is for
at least 1 minute and do not operate the ignition switch, other
switches or doors.
If the result is not as specified, the DLC3 may have a
malfunction. Repair or replace the harness and connector.
HINT:
Connect the cable of the intelligent tester to the DLC3, turn
the ignition switch ON and attempt to use the tester. If the
screen displays UNABLE TO CONNECT TO VEHICLE, a
problem exists in the vehicle side or the tester side.

If communication is normal when the tester is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tester is
connected to another vehicle, the problem is probably in the
tester itself. Consult the Service Department listed in the
tester's instruction manual.
6. CHECK MIL
(a) Check that the MIL illuminates when turning the
ignition switch ON.
If the MIL does not illuminate, there is a problem in
the MIL circuit (see page ES-386).
(b) When the engine is started, the MIL should turn off.
7. ALL READINESS
(a) For this vehicle, using the intelligent tester allows
readiness codes corresponding to all DTCs to be
read. When the diagnosis (normal or
malfunctioning) has been completed, readiness
codes are set. Enter the following menus:
ENHANCED OBD II / MONITOR STATUS.
DTC CHECK / CLEAR
1. CHECK DTC
(a) DTCs which are stored in the ECM can be displayed
with the intelligent tester.
The intelligent tester can display pending DTCs and
current DTCs. Some DTCs are not stored unless a
malfunction is detected in consecutive driving
cycles. When a malfunction is detected in only one
driving cycle, it is stored as a pending DTC.
(1) Connect the intelligent tester to the CAN VIM.
Then connect the CAN VIM to the DLC3.
(2) Turn the ignition switch ON and turn the tester
ON.
(3) Enter the following menus: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES (or PENDING CODE).
(4) Confirm the DTCs and freeze frame data and
then write them down.
(5) Confirm the details of the DTCs (see page AX-
35).
NOTICE:
When simulating a symptom with the scan
tool to check for DTCs, use normal mode.
For codes on the DIAGNOSTIC TROUBLE
CODE CHART subject to "2 trip detection
logic", perform the following actions.
Turn the ignition switch OFF after the
symptom is simulated once. Then repeat the
simulation process again. When the
symptom has been simulated twice, the MIL
illuminates and the DTCs are recorded in the
ECM.

1. DESCRIPTION
HINT:
When using a chassis dynamometer, brake tester, etc. to
perform a vehicle test, activate test mode to avoid a
"different tire diameter installed" incorrect judgment.
Test mode does not have a 4WD parameter. Test mode
is activated because it will prohibit a different tire
diameter judgment.
2. ACTIVATE TEST MODE
HINT:
Activate test mode before using a chassis dynamometer,
brake tester, etc. to perform a vehicle test.
(a) Check that the ignition switch is OFF.
(b) Use either of the following methods to change the
4WD ECU to test mode.
(1) Test mode activation through intelligent tester
(with CAM VIM).
• Connect the intelligent tester (with CAM VIM)
to the DLC3 connector and turn the ignition
switch ON. Using the test mode activation
function (mode 10), activate test mode.
(2) Test mode activation by shorting TS terminal
• With the ignition switch OFF, short-circuit the

DIAGNOSIS SYSTEM
1. DESCRIPTION
Active torque control 4WD system data can be read in
the Data Link Connector 3 (DLC3) of the vehicle. When
the system seems to be malfunctioning, use the
intelligent tester (with CAN VIM) to check for
malfunctions and perform repairs. Therefore when there
seems to be a problem with the active torque control
4WD, use the intelligent tester (with CAN VIM) or SST to
check and troubleshoot it.
SST 09843-18040
2. CHECK DLC3
(a) The ECU uses CAN (ISO11898-1) and ISO9141-2
for communication protocol. The terminal
arrangement of the DLC3 complies with SAE J1962
and matches the ISO9141-2 format.
Verify the conditions listed in the table below.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, 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:
Connect the cable of the intelligent tester (with CAN
VIM) to the DLC3, turn the ignition switch ON and
attempt to use the tester. If the display indicates that
a communication error has occurred, there is a
problem either with the vehicle or with the tester.
• If communication is normal when the tester is
connected to another vehicle, inspect the DLC3
of the original vehicle.
