Wiring Diagram

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 adaptor 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.

DTC Will Set when
The combined resistance of the passenger air bag (inflator) module (1st stage), harness wiring and connector terminal contact is above a specified value for specified time.
