[08/2014 - ]
CHECK MODE PROCEDURE
HINT:
Techstream:
Compared to the 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 erased 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) Transmission in the P or N position.
(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.

(ETCS)
ECM cuts off throttle actuator current and

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.
