Automatic Transmission System (For 1Kd-Ftv With I-Art) Check Mode Procedure

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 stored with 1-trip detection logic.

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. A/C off.
   

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

Enter the following menus: Powertrain / ECT / Utility / Check Mode.

Check that the MIL flashes as shown in the illustration.

NOTICE:

1. All DTCs and freeze frame data will be cleared if: 1) the GTS is used to change the TCM 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.
   
2. Before changing to check mode, make a note of the DTCs and freeze frame data.
   

Start the engine. The MIL should turn off after the engine starts.

Perform "Monitor Drive Pattern" for the ECT test (HILUX_TGN26 RM000000W7K0PNX.html), or reproduce the conditions of the malfunction described by the customer.

After reproducing the malfunction conditions, use the GTS to check the DTC and freeze frame data.
