 Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time o\
f the malfunction.
1READ VALUE OF HAND±HELD TESTER(INLET AIR TEMPERATURE)
(a)Connect the hand±held tester to the DLC3.
(b)Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(c)Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / AMBI TEMP SENSº and read its value displayed on the hand±held tester.
Temperature: Same value as the actual diesel turbo inlet air temperature.\
Result:
Temperature DisplayedProceed to
±40C (±40 )A
140 C (284 ) or moreB
OK (Same as present temperature)C
HINT:

If there is an open circuit, the hand±held tester indicates ±40 C (±40 F).

If there is a short circuit, the hand±held tester indicates 140 C (284 F) or more.

INSPECTION PROCEDURE
HINT:

After completing repair, confirm P0087 is not set again.

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time of the malfunction.
1 READ VALUE OF HAND±HELD TESTER(FUEL PRESSURE)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand±held tester main switch ON.
(c) Start the engine.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / COMN RAIL PRESSº.
(e) Check that internal fuel pressure of the common rail is within specification below.
Reference:
Engine SpeedFuel Pressure (MPa)
IdlingApprox. 30 to 40
Running the engine at 2,500 rpm (No engine load)Approx. 50 to 100
