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 harness, connector or terminal is found damaged, replace the wire harness, connector and terminal as an assembly.
