Check Mode Procedure

WARNING: This page is about a different car, the 2009 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.

CHECK MODE (SIGNAL CHECK): DTC CHECK
1. Connect the Techstream to the DLC3.
2. Turn the power switch ON (IG).
3. Select the SIGNAL CHECK, and proceed to check 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 the check mode inspection when a malfunction in each squib circuit is suspected even after the normal system code is output through the normal diagnosis mode inspection.
