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.

StepAction YesNo
1 1) Disconnect forward-sensor connector “E13”.
2) Disconnect SDM connector “L29”.
3) Check proper connection to SDM connector at terminals “L29-50” and “L29-51” or terminals.
4) Check proper connection to forward-sensor connector at terminals “E13-1” and “E13-2”.
5) Using service wire (1), connect “E13-1” terminal and “E13-2” terminal of forward-sensor connector.
6) Measure resistance between terminals “L29-50” and “L29-51” of SDM connector.
Special tool
(A): 09932-76010
Is each measured resistance 1
Ω or less? Go to Step 2. High resistance or open
wire in “ORN” circuit or
“PNK/BLK” circuit.
2 1) Disconnect service wire from “E13” connector. 2) Measure voltage between “L29-50” terminal and body ground, “L29-51” terminal and body ground.
With ignition switch ON, is each measured value 1 V or less? Go to Step 3. “ORN” circuit or “PNK/
BLK” circuit shorted to
power supply circuit.
3 1) Check forward-sensor referring to “Forward-Sensor Inspection”.
Is it in good condition? Substitute a known-
good SDM and recheck.
Replace forward-sensor
referring to “Forward-
Sensor Removal and
Installation”. If DTC still
exists, substitute a
known-good SDM and
recheck.
