Air Bag System Check

Print


WARNING
Disconnect and isolate the negative battery cable before beginning any air bag system component removal or installation procedure. This will disable the air bag system. Failure to disconnect the battery could result in accidental air bag deployment and possible personal injury. Allow system capacitor to discharge for 2 minutes before removing any air bag components.

WITH A SCAN TOOL



The use of a DRB scan tool is required to ENSURE proper air bag system operation. If you have a DRB scan tool perform the test outlined below and follow the tool manufactures procedure to verify that there are no faults codes stored which would affect air bag operation

  1. Disconnect the negative battery cable and isolate.
  2.  
  3. Remove forward console or cover as necessary.
  4.  
  5. Connect a scan tool to the ACM data link 6-way connector, located at right of steering column.
  6.  
  7. Turn the ignition key to ON position. Exit vehicle with DRB. Use the latest version of the proper cartridge.
  8.  
  9. After checking that no one is inside the vehicle, connect the negative battery cable.
  10.  
  11. Using the DRB, read and record active diagnostic data.
  12.  
  13. Read and record any stored diagnostic codes.
  14.  
  15. Correct any problems found in Steps 6 and 7.
  16.  
  17. Erase stored diagnostic codes if there are no active diagnostic codes. If problems remain, diagnostic codes will not erase.
  18.  
  19. Turn the ignition key to OFF then ON and observe the message center air bag lamp. It should go on for six to eight seconds, then go out; indicating system is functioning normally.
  20.  
  21. If air bag warning lamp either fails to light, blinks on and off or goes on and stays on, there is a system malfunction.
  22.  

WITHOUT A SCAN TOOL



The use of a scan tool is required to ENSURE proper air bag system operation. If you do not have a DRB, or equivalent scan tool, perform the steps outlined below to verify proper air bag system operation before connecting the negative battery cable. But, keep in mind that improper wiring during repair procedures could result in accidental air bag deployment when the negative battery cable is connected. The ONLY way to be sure this will not occur is to use a scan tool to perform system diagnostics BEFORE the battery is connected (returning power to the deployment module). DO NOT proceed with repairs if you are uncertain of your ability to properly reconnect all wiring without damage.

  1. Disconnect the negative battery cable, then wait at least two minutes before working on the air bag system.
  2.  
  3. After performing the repair or replacement procedure, do not immediately connect the negative battery cable.
  4.  
  5. Ensure that the component(s) repaired or replaced are approved by the vehicle manufacturer.
  6.  
  7. Ensure that the components are retained by the proper type and grade of fastener.
  8.  
  9. Verify that all electrical connections are engaged properly. Improper wiring during repair procedures could result in accidental air bag deployment when the negative battery cable is engaged, resulting in personal injury or even death.
  10.  
  11. Ensure that no one is in the vehicle, then connect the negative battery cable.
  12.  
  13. Turn the ignition key to OFF then ON and observe the message center air bag lamp. It should go on for six to eight seconds, then go out; indicating the system is functioning normally.
  14.  
  15. If air bag warning lamp either fails to light, blinks on and off or goes on and stays on, there is a system malfunction. If this happens repeat Steps 3-7.
  16.  
  17. If air bag warning lamp still fails to light, blinks on and off or goes on and stays on, there is still a system malfunction.
  18.  
  19. The vehicle should then be towed, not driven, to a repair facility and inspected by a technician.
  20.
