CHECK MODE PROCEDURE

1. CHECK MODE (SIGNAL CHECK): DTC CHECK

NOTICE:

Select Signal Check from the DTC Check screen displayed on the Techstream to clear the output DTCs (both present and past).

  • 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.
