1996 TOYOTA T100 (RM449U)
The 2 trip repeats the same mode a 2nd time (How-
ever, the ignition switch must be turned OFF be-
tween the 1st trip and 2nd trip.).
Freeze frame data:
Freeze frame data records the engine condition
when a misfire (DTCs P0300 − P0304) or fuel trim
malfunction (DTCs P0171, P0172) or other mal-
function (first malfunction only), is detected.
Because freeze frame data records the engine
conditions (fuel system, calculator load, engine
coolant temperature, fuel trim, engine speed, ve-
hicle speed, etc.) when the malfunction is detected,
when troubleshooting it is useful for determining
whether the vehicle was running or stopped, the en-
gine warmed up or not, the air−fuel ratio lean or rich,
etc. at the time of the malfunction.
Priorities for troubleshooting:
If troubleshooting priorities for multiple DTCs are given in the
applicable DTC chart, these should be followed.
If no instructions are given troubleshoot DTCs according to the
following priorities.
(1) DTCs other than fuel trim malfunction (DTCs
P0171, P0172), EGR (DTCs P0401, P0402), and
misfire (DTC P0300 − P0304).
(2) Fuel trim malfunction (DTCs P0171, P0172), and
EGR (DTCs P0401, P0402).
(3) Misfire (DTCs P0300 ∼ P0304).
(b) Check the DLC3.
The vehicle’s ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.

1996 TOYOTA T100 (RM449U)
(b) Clear the DTC.
The following actions will erase the DTCs and freezed
frame data.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes. (See the OBD II scan tool’s instruction book
for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand−held tester switches the ECM from
normal mode to check mode or vice−versa, or if the igni-
tion switch is turned from ON to ACC or OFF during check
mode, the DTCs and freezed frame data will be erased.

5. CHECK FOR INTERMITTENT PROBLEMS
HINT:
TOYOTA HAND−HELD TESTER only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(a) Clear the DTC (See step 3).
(b) Set the check mode (See step 3).
(c) Perform a simulation test (See page IN−16).
(d) Check the connector and terminal (See page IN−26).
(e) Handle the connector (See page IN−26).
