Circuit/System Verification

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE:

    The passenger air bag ON and OFF indicators may not operate as expected if there are supplemental inflatable restraint (SIR) DTCs. Repair all SIR DTC before proceeding with this diagnostic.

  1. Ignition ON, the passenger air bag ON and OFF indicators should both illuminate for approximately 5 seconds for a bulb check.
  2. Monitor the parameter Passenger Classification in Passenger Presence System with a scan tool. With the passenger seat unoccupied, the parameter should display Empty Seat. The passenger air bag OFF indicator should illuminate.
  3. Apply enough weight on the passenger seat to change the parameter display to Occupied. The passenger air bag indicator should switch from OFF to ON within 5 seconds.
