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 specified digital
multimeter (Refer to “Special Tool”.) 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 Intermittents and Poor
Connections”.
• If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
