Check Mode Procedure

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

CHECK MODE (SIGNAL CHECK): DTC CHECK
1. Connect an intelligent tester or Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Select "SIGNAL CHECK", and proceed with checking using the tester.
  NOTE: Select "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the tester 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.
