8B-69 Air Bag System:
DTC 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.
• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.
Step Action Yes No
1 Was “Air Bag Diagnostic System Check Flow” performed? Go to Step 2. Go to “Air Bag
Diagnostic System
Check Flow”.
2 Forward impact-sensor circuit check
1) Disconnect forward impact-sensor connector “E40”.
2) Disconnect SDM connector “L04”.
3) Check for proper connection to SDM connector at
terminals “L04-50” and “L04-51”.
4) Check for proper connection to forward impact-sensor
connector at terminals “E40-1” and “E40-2”.
5) Measure resistance between “L04-50” and “E40-2”
terminals, between “L04-51” and “E40-1” terminals.
Special tool
(A): 09932–76010
Is each measured resistance 1
Ω
or less?
Go to Step 3. Repair high resistance
or open in defective
circuit.
3 Forward impact-sensor circuit check
1) With ignition turned ON, measure voltage between “L04-
50” terminal and body ground, between “L04-51”
terminal and body ground.
Special tool
(A): 09932–76010
Is each measured voltage 0 V?
Replace forward
impact-sensor, and
recheck.
If DTC still detected,
replace SDM. Repair short to power
supply circuit or other
circuit in defective
circuit.
