Check Mode Procedure

WARNING: This page is about a different car, the 2007 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

CHECK MODE (SIGNAL CHECK)
1. Connect the intelligent tester (with CAN VIM) to the DLC3.
2. Turn the ignition switch ON.
3. Select the "SIGNAL CHECK", and continue checking with the intelligent tester.
  NOTE: Select the "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the intelligent tester to clear the output DTCs (both present and past).
  
  HINT:
  - Check mode is more sensitive to malfunctions than normal mode.
  - If the normal system code is output in normal mode even when a sensor signal malfunction is suspected, perform the inspection in check mode.
