CAUTION
!
• Be sure to perform "Air Bag Diagnostic System Check" before starting diagnosis according to flow
table.
• 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.
Flow Test Description
Step 1: Check for loose connection between diagnosis switch terminal and ground terminal by service wire.
Step 2: Check for open circuit in diagnosis switch circuit.
Troubleshooting
Step
1 1) Inspect connection between diagnostic switch terminal
in "AIR BAG" monitor coupler and body ground.
Are they securely connected by service wire?
2 1) Disconnect SDM connector "L70" (3) from SDM.
2) Check for proper connection at "PPL" wire ("L70-8"
terminal in SDM connector and "L79-2" terminal in "AIR
BAG" monitor coupler "L79") terminals.
3) If OK, then measure resistance between "L70-8"
terminal and "L79-2" terminal.

NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components, ensure all components are properly mounted.
• Repeat "Air Bag Diagnostic System Check" to confirm that the trouble has been corrected.
