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 harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
Forward-sensor abnormal signal is detected by SDM.
Flow Test Description
Step 1: Check for short circuit between forward-sensor circuit and ground.
Step 2: Check if malfuncti on is in forward-sensor.
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 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) Measure resistance between “L29-50” terminal and body ground, “L29-51” terminal and body ground.
