Check Mode Procedure

CHECK MODE PROCEDURE




1. Check mode (Signal check): DTC CHECK
a. Connect the hand-held tester to the DLC3.
b. Turn the ignition switch on (IG).
c. Select the "SIGNAL CHECK", and proceed checking with the hand-held tester.

NOTE: Select the "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the hand-held 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.
