Check the pending fault code using the Continuous
Test Results function (Mode 7 for SAE J1979) on the
OBD II scan tool.
(b) Clearing the DTCs using the OBD II scan tool or the
hand-held tester.
(1) Connect the OBD II scan tool or the hand-held tes-
ter to the DLC3.
(2) Turn the ignition switch ON.
(3) Erase DTCs and freeze frame data with the OBD II
scan tool (complying with SAE J1978) or the hand-
held tester. For the hand-held tester: 1) enter the
following menus: DIAGNOSIS / ENHANCED OBD
II / DTC INFO / CLEAR CODES; and 2) press YES.
For the OBD II scan tool, see its instruction manual.
(c) Clearing the DTCs not using the OBD II scan tool or the
hand-held tester.
Remove the EFI or ECD No. 1 and ETCS fuses from the
engine room J/B for more than 60 seconds, or disconnect
the battery terminal for more than 60 seconds.
After disconnecting the battery terminal, perform the ºINI-
TIALIZE procedure.
3. DTC CHECK (Check Mode)
HINT:
Hand-held tester only:
Check mode has a higher sensitivity to detect malfunctions and
can detect malfunctions that normal mode cannot detect.
Check mode can also detect all the malfunctions that normal
mode can detect.
(a) Follow these steps when preparing to use the hand-held
tester check mode.
(1) Make sure that the items below are true:
Battery positive voltage 11 V or more
Throttle valve fully closed
Transmission in the P or N position
A/C switched OFF
(2) Turn the ignition switch OFF.
(3) Connect the hand-held tester to the DLC3.
(4) Turn the ignition switch ON.
(5) Change the ECM to check mode with the hand-
held tester. Enter the following menus: DIAGNOSIS
/ ENHANCED OBD II / CHECK MODE. Make sure
the MIL flashes as shown in the illustration.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand-held tester is used to change the ECM from
normal mode to check mode or vice-versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or OFF.

If the Electronic Throttle Control System (ETCS) has a mal-
function, the ECM cuts off current to the throttle control
motor. The throttle control valve returns to a predetermined
opening angle (approximately 16) by the force of the return
spring. The ECM then adjusts the engine output by control-
ling the fuel injection (intermittent fuel-cut) and ignition tim-
ing in accordance with the accelerator pedal opening angle
to enable the vehicle to continue at a minimal speed.
If the accelerator pedal is depressed firmly and slowly, the
vehicle can be driven slowly. If the accelerator pedal is
depressed quickly, the vehicle may speed up and slow
down erratically.
ºPassº condition is detected and then the ignition switch is
turned OFF.

The accelerator pedal position sensor has two (main and
sub) sensor circuits. If a malfunction occurs in either of the
sensor circuits, the ECM detects the abnormal signal volt-
age difference between the two sensor circuits and
switches to limp mode. In limp mode, the remaining circuit
is used to calculate the accelerator pedal opening to allow
the vehicle to continue driving.
If both circuits malfunction, the ECM regards the opening
angle of the accelerator pedal to be fully closed. In this
case, the throttle valve will remain closed as if the engine is
idling.
ºPassº condition is detected and the ignition switch is turned
OFF.
5. CHECK FOR INTERMITTENT PROBLEMS
Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is
in check mode with hand-held tester. In check mode, the ECM uses 1 trip detection logic, which has a higher
sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.
(a) Clear the DTCs. (See step 2)
(b) Set the check mode. (See step 3)
(c) Perform a simulation test (See page IN-26).
(d) Check the connector and terminal (See page IN-36).
(e) Wiggle the harness and connector (See page IN-36).
