CHECK MODE (SIGNAL CHECK): DTC CHECK
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Select Signal Check, and proceed with checking using the intelligent tester.
Note
Select Signal Check from the DTC Check screen displayed on the intelligent tester to clear the output DTCs (both present and past).
Tech Tips
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.
