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.

REMOVAL
1. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
• DISCHARGE FUEL SYSTEM PRESSURE
procedures must be performed before
disconnecting any part of the fuel system.
• After performing the DISCHARGE FUEL SYSTEM
PRESSURE procedures, pressure will remain in
the fuel line. When disconnecting the fuel line,
place a cloth or equivalent over fittings to reduce
the risk of fuel spray.
(a) Remove the console box (see page IR-83).
(b) Disconnect the connector.
(c) Start the engine. After the engine has stopped, turn
the ignition switch off.
HINT:
DTC P0171 (system too lean) may be set.
(d) Check that the engine does not start.
(e) Remove the fuel tank cap, and let the air out of the
fuel tank.
(f) Connect the connector.
(g) Install the console box (see page IR-90).
2. DISCONNECT CABLE FROM NEGATIVE BATTERY
TERMINAL
CAUTION:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
3. REMOVE NO. 1 ENGINE COVER (See page ES-410)
4. REMOVE AIR CLEANER CAP SUB-ASSEMBLY (See
page ES-411)
