SERVICE INFORMATION

This bulletin provides information to update the Airbag Control Unit (ACU) software logic on 2014MY Soul (PS) produced from July 21, 2013 through June 20, 2014. In the rare event that communication to the ACU from both the left and right front impact sensors is simultaneously lost early in a severe crash, before frontal airbag deployment is commended by the ACU, the front airbags will not deploy. Non-deployment of the frontal airbags increases the risk of injury.

Follow the procedure outlined in this publication to update the ACU software logic. Before conducting the procedure, verify that the vehicle is included in the list of affected VINs.

NOTE: There is no charge to the vehicle owner for this repair. Under applicable law, you may not sell or otherwise deliver any affected vehicle until it has been repaired pursuant to the procedures set forth in this bulletin.

NOTE: To assure complete customer satisfaction, always remember to refer to WebDCS Warranty Coverage (validation) Inquiry Screen (Service → Warranty Coverage → Warranty Coverage Inquiry) for a list of any additional campaigns that may need to be performed on the vehicle before returning it to the customer.
