ON-BOARD DIAGNOSTIC FUNCTION [AIR BAG SYSTEM]

id0802a0100500

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 control module module configuration is performed, the air bag system warning light will flash. Approx. 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.

PID/Data Monitoring Function

• By using the PID/data monitoring function, the monitored item of the input/output signal, as set on the SAS control module, can be freely selected and read out in real-time.
• An SST (WDS or equivalent) is used to read out PID/data monitor information.
