A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 17-17-13R | 2018-05-29. Service bulletin. AIR BAGS; ELECTRICAL SYSTEM; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. NOTE: The Airbag systems used on previous and current WRX, STI and Tribeca models are NOT equipped with EDR functionality. This Bulletin provides information regarding Event Data Recorder (EDR) functionality which has been incorporated into the airbag system. The function of the EDR is best explained using the following statements found in the vehicle Owner?s Manual: ?This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations such as an airbag deployment or hitting a road obstacle, data that will assist in the understanding how a vehicle?s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: ? How various systems in your vehicle were operating; ? Whether or not the driver and passenger safety belts were buckled/fastened; ? How far (if at all) the driver was depressing the accelerator and/or brake pedal; ? How fast the vehicle was traveling. This data can help provide a better understanding of the circumstances in which crashes and injuries occur. |

The warning box is located inside the overhead map light assembly as shown in the illustrations below. The warning box part number has also been changed. On affected vehicles, the passenger?s airbag ON/OFF indicator flashes, the airbag warning lamp illuminates and DTC B1661: ?PASSENGER?S AIRBAG ON/OFF INDICATOR FAILURE? is stored. This DTC indicates communication between the warning box and combination meter has failed. The condition is more likely to be observed during high ambient temperature conditions. In some cases, there may also be a DTC B1502: ?WARNING BOX COMMUNICATION MALFUNCTION? stored in the combination meter memory. |
