Air Bag System: 8B-26
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
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.
Step Action Yes No
1 1) Inspect connection between diagnostic switch terminal
in “AIR BAG” monitor coupler and body ground.
Are they securely connected by service wire?
Go to Step 2. Properly connection
diagnostic switch
terminal on “AIR BAG”
monitor coupler and
body ground 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.
Special tool
(A): 09932-76010
Is resistance 0 – 1
Ω
?
Substitute a known-
good SDM and recheck Check “PPL” wire
terminals.
If OK, repair high
resistance or open in
“PPL” wire.
