Check Mode Procedure

WARNING: This page is about a different car, the 2008 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

CHECK MODE (SIGNAL CHECK): DTC CHECK
1. Turn the ignition switch off.
2. Connect the Techstream to the DLC3.
3. Turn the ignition switch on (IG) and turn the Techstream on.
4. Select the "SIGNAL CHECK", and proceed checking with the Techstream.
  NOTE: Select the "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the Techstream to clear the output DTCs (both present and past).
  
  HINT:
  - DTCs can be detected more sensitively in check mode than in normal diagnosis mode.
  - Perform check mode inspection when a malfunction in each squib circuit is suspected even after the normal system code is output through normal diagnosis mode inspection.
