Downloaded from www.Manualslib.com manuals search engine Air Bag System: 8B-17
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.

Flow Test Description
Check for short circuit between diag nosis switch circuit and ground.
Troubleshooting
NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

DTC B1013: SDM faultS7RS0B8204010
DTC Will Set when
An internal SDM fault is detected by SDM.
NOTE
DTC B1013 can never be cleared once it has been set.

DTC Troubleshooting 1) Turn ignition switch OFF.
2) Replace SDM.
3) Repeat “Air Bag Diagnostic System Check”.
DTC B1014: “AIR BAG” Warning Right Circuit FailureS7RS0B8204011
Wiring DiagramStep Action Yes No
1 1) With ignition switch OFF, disconnect SDM connector “L29”.
2) Check “L29-35” terminal of SDM.
Is it shorted to ground terminal or harness? Clean up terminal. Substitute a know-good
SDM and recheck.
