Circuit/System Verification

  1. Verify the OnStar system is not damaged and is functioning properly with no DTCs set.
    • If the OnStar system is damaged, inoperative, or any OnStar DTCs are set, these concerns must be corrected before the start disable can be removed.
  2. Press the blue OnStar button and ask the advisor to be transferred to the stolen vehicle team to verify the vehicle account has been updated.
  3. Very that OnStar is aware the vehicle has been recovered and that the vehicle account has been updated as such.
    • If OnStar has not been notified that the vehicle has been recovered, contact the customer and advise them that for security purposes, they must contact OnStar and the law enforcement agency to update the vehicle account.
  4. After the vehicle account has been updated and the start disable request has been removed, DTC B302A will transition to a history DTC. Clear the history DTC.
