When the airbag warning light or Supplemental Restraint System (SRS) light illuminates on the PT Cruiser's instrument panel, it is because a trouble code is being sent to the On-Board Diagnostics (OBD) computer from a sensor in the SRS. Trouble codes are used to help you pinpoint and troubleshoot problems with your PT Cruiser. You can reset these trouble codes using an OBD scan tool after you have had the airbag system examined and repaired. This hand-held computerised device can be purchased from your dealership or any auto parts retailer.
