Toyota Camry (XV70): Check Mode Procedure

CHECK MODE PROCEDURE

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 of the malfunctions that normal mode can detect. In check mode, DTCs are detected with 1 trip detection logic.

CHECK MODE PROCEDURE

(a) Make sure that the following conditions are met:

• The battery voltage is 11 V or more.
• The throttle valve is fully closed.
• The shift lever is in P or N.
• The air conditioning is off.

(b) Connect the Techstream to the DLC3.

(d) Turn the Techstream on.

(e) Enter the following menus: Powertrain / Transmission / Utility / Check Mode.

(f) Change the ECM to check mode and check that 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 engine switch is turned from on (IG) to off.

Before entering check mode, make a note of the DTCs and freeze frame data.

(g) Start the engine. The MIL should turn off after the engine starts.
