Improved safety
• A driver-side air bag module has been adopted.
• A passenger-side air bag module has been adopted.
• A curtain air bag module has been adopted.
• A side air bag module has been adopted.
• A pre-tensioner seat belt has been adopted.
• Three-point seat belt with the following functions for front seat passengers adopted

ON-BOARD DIAGNOSTIC FUNCTION OUTLINE
DPE080200000T01
• The air bag system has an on-board diagnostic function to facilitate the system diagnosis.
• The on-board diagnostic function consists of the following functions: a malfunction detection function, which
detects overall malfunctions in the air bag system-related parts; a memory function, which stores detected
DTCs; a display function, which indicates system malfunctions by DTC display; a PID/data monitoring function,
which reads out specific input/output signals.
• Using the WDS or equivalent, DTCs can be read out and deleted, and the PID/data monitoring function can be
activated.
• The system has a fail-safe function to prevent the accidental activation of the air bags in case of an air bag
system malfunction.

ON-BOARD DIAGNOSTIC FUNCTION
DPE080200000T02
Self-Malfunction Diagnostic Function
Malfunction detection function
• Detects overall malfunctions in the air bag system-related parts.
Fail-safe function
• If the SAS control module performance/function cannot be maintained due to any cause, the fail-safe function
stops air bag system control and flashes the air bag system warning light to prevent the air bags from operating
(deploying) accidentally.
Memory function
• Stores malfunctions in the air bag system-related parts detected by the malfunction detection function, and the
stored malfunction contents are not cleared even if the ignition switch is turned to the LOCK position or the
negative battery cable is disconnection.
Display function
• When the malfunction detection function detects a malfunction, the air bag system warning light illuminates to
advise the driver. Using the external tester communication function, DTCs can be output to the DLC-2 via the
K-Line.
