Toyota Tacoma (2015-2018) Service Manual: Check Mode Procedure
CHECK MODE PROCEDURE
1. DESCRIPTION
(a) Check mode has a higher sensitivity to malfunctions and can detect malfunctions that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect. In check mode, DTCs are detected with 1 trip detection logic.
2. CHECK MODE PROCEDURE
(a) Make sure that the following conditions are met:
(1) Battery positive voltage 11 V or higher.
(2) Throttle valve fully closed.
(3) Shift lever in P or N.
(4) Air conditioning 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) Change the ECM to check mode. Make sure the MIL flashes as shown in the illustration.

NOTICE:
All DTCs and freeze frame data will be cleared if: 1) the Techstream 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.
Before entering check mode, make notes of the DTCs and freeze frame data.
(h) Start the engine. The MIL should turn off after the engine starts.
(i) Perform Monitor Drive Pattern for the ECT test (See page

).
(Or, simulate the conditions of the malfunction described by the customer.)
(j) After simulating the malfunction conditions, use the Techstream to check the DTC and freeze frame data.
