8B-14 Air Bag System:
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 harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
Flow Test Description
Step 1: Check for “A/BAG” fuse blown.
Step 2, 3: Check for loose connection between junction block assembly connector and junction block
assembly.
Step 4: Check for loose connection between SDM connector and SDM.
Step 5: Check for SDM power supply circuit.
Step 6: Check for short circuit between “AIR BAG” warning right circuit and ground.
Troubleshooting
Step Action Yes No
1 1) Turn ignition switch OFF.
2) Remove and inspect “A/BAG” fuse.
Is fuse good?
Go to Step 2. “RED” wire short to
ground.
After repair, replace “A/
BAG” fuse.
2 1) Check for loose connection of junction block assembly
connector “L04”.
Is it connected securely?
Go to Step 3. Correct connector “L04”
securely.
3 1) Check for loose connection of junction block assembly
connector “G34”.
Is it connected securely?
Go to Step 4. Correct connector “G34”
securely.
4 1) Check for loose connection of SDM connector “L29”.
Is it connected securely?
Go to Step 5. Correct connector “L29”
securely.
5 1) Disconnect SDM connector “L29”.
2) Check proper connection to SDM at terminal “L29-27”.
3) If OK, then check voltage between “L29-27” terminal of
SDM connector and body ground with ignition switch
ON.
Special tool

Is it 8 V or more?
Go to Step 6. “RED” wire (between “A/
BAG” fuse and SDM
connector) open or
“GRN” wire (between
ignition switch and “A/
BAG” fuse) open or
short to ground.
