CHECK MODE PROCEDURE

Turn the engine switch on (IG).

Select the "SIGNAL CHECK", and proceed checking using the intelligent tester.

NOTICE:

Select the "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the intelligent tester to clear the output DTCs (both present and past).

HINT:

1. DTCs can be detected more sensitively in check mode than in normal diagnosis mode.
   
2. 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.
