- Summary
- 09184b - customer satisfaction (revised vehicle population, condition statement and service procedure). Certain vehicles currently or previously registered in alaska, connecticut, delaware, district of columbia, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, and wisconsin may have a condition in which the sensing and diagnostic module (sdm) may corrode due to a significant quantity of snow and/or water containing road salt or other contaminants entering the vehicle and saturating the acoustical padding beneath the carpet. The sdm is located under the drivers seat beneath the acoustical padding. If sufficient moisture collects and is retained in the padding, it may cause excessive corrosion under the sdm that could compromise the module seal and allow water intrusion that could result in sdm malfunction. If this condition exists, the airbag readiness light or a service airbag" message on the driver information center (dic) may illuminate. In rare cases, the vehicle may contact onstar® and the seat belt pretensioners or front airbags may deploy. Dealers are to remove the acoustical pad above the sdm, inspect the sdm, and replace the sdm, if necessary.
