Self-Malfunction Diagnostic Function
• The self-malfunction diagnosis function determines that there is a malfunction, outputs a signal, as a DTC, to
the DLC-2, and at the same time, flashes the air bag system warning light to advise the driver of a malfunction.
• The air bag system warning light illuminates or flashes to indicate a single DTC according to the present
malfunction. (If there is more than one present malfunction, only one DTC will be displayed according to the
preset priority ranking.)
• The air bag system warning light will flash the DTC pattern for five cycles, and then will remain illuminated until
the ignition switch is turned to the LOCK position.
• If both of the driver-side air bag module connectors are disconnected when SAS unit module configuration is
performed, the air bag system warning light will flash. Appro. 15 seconds after the connectors are properly
reconnected, the light will go out.
• The self-malfunction diagnostic function consists of two function: present malfunction diagnostic and past
malfunction diagnostic. The function of present malfunction diagnostic and past malfunction diagnostic are the
same as that of the 626 (GF) model.
