- ]
CHECK MODE PROCEDURE
HINT:
Compared to normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can
detect the malfunctions that cannot be detected in normal mode.
NOTICE:
All the stored DTCs and freeze frame data are cleared if: 1) the ECM is changed from normal mode to
check mode or vice versa; or 2) the ignition switch is turned from ON to ACC or off while in check mode.
Before changing modes, always check and note any DTCs and freeze frame data.
1. CHECK MODE PROCEDURE
(a) Check and ensure the following condition:
(1) Battery positive voltage 11 V or more.
(2) Throttle valve fully closed.
(3) Shift lever in P or N.
(4) A/C switch OFF.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Utility / Check Mode.
(g) Switch the ECM from normal mode to check mode.
(h) Make sure the MIL flashes as shown in the illustration.
(i) Start the engine.
(j) Make sure the MIL turns OFF.

Electronic Throttle
Control System (ETCS)
ECM cuts off throttle actuator current and
throttle valve returned to 7° throttle
position by return spring.
ECM then adjusts engine output by
controlling fuel injection (intermittent
fuel-cut) and ignition timing in accordance
with accelerator pedal opening angle to
allow vehicle to continue at minimal
speed*1.
Pass condition

ignition switch
turned off
