OBD 139
16.0 AIRBAG
Toyota vehicles use three different types of Airbag controllers:
•OBD Airbag
•OBD Side Airbag
• Multiplex-OBD (M-OBD) Airbag/Supplemental Restraint System (SRS)
The diagnostic functions available vary depending on the type of Airbag controller. The
connector used for diagnosis provides a clue to the type of controller the vehicle has.
• OBD Airbag and Side Airbag controllers are diagnosed using either the CHECK or
TDCL connectors.
• M-OBD controllers are diagnosed using the DLC3 connector.
The diagnostic modes for each type of Airbag controller are described separately in this
manual. See Section 16.1: OBD AIRBAG, Section 16.2: SIDE AIRBAG, and Section
16.3: M-OBD AIRBAG/SRS.
