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.
