B1024

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 table, 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.

NOTE: If vehicle is equipped with driver or passenger side air bag ON-OFF switch, perform "Air Bag Diagnostic System Check Flow" with disconnecting air bag ON-OFF switch from air bag circuit. And if this DTC is not detected under the condition, replace air bag ON-OFF switch and recheck.

DTC Will Set When
The voltage measured at driver air bag initiator circuit is below a specified value for specified time.

Test Description

DTC Troubleshooting

NOTE:
Upon completion of inspection and repair work, perform the following items.
- Reconnect all air bag system components, ensure all components are properly mounted.
- Clear diagnostic trouble codes (Refer to "DTC Clearance"),if any.
- Repeat "Air Bag Diagnostic System Check" to confirm that the trouble has been corrected.
