CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor Connections”.
• If there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
DTC Will Set when
The combined resistance of the side-air bag (inflator) module (driver or passenger), harness wiring and connector
terminal contact is above a spec ified value for specified time.

SDM InspectionS7RS0B8206004
WARNING!
During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM).
Be sure to read “Precautions on Service and
Diagnosis of Air Bag System” before starting
to work and observe every precaution during
work. Neglecting them ma y result in personal
injury or inactivation of the air bag system
when necessary.
CAUTION!
