RECAL CAMPAIGN 2019020004 - PERFORM SCN CODING IN SUPPLEMENTAL RESTRAINT SYSTEM (SRS) CONTROL UNIT

SERVICE CAMPAIGN BULLETIN

Reference Number(s): P-RC-2019020004, Date of Issue: February 01, 2019

MERCEDES-BENZ:

Model GLC-Class (253 platform) Model Year 2018-2019

SUBJECT

Model GLC-Class (253 platform)

Model Year 2018-2019

Perform SCN coding in Supplemental Restraint System (SRS) control unit

Daimler AG ("DAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year ("MY") 18-19 GLC-Class (253 platform) AMG vehicles, the airbag control unit software parameters might not meet production specifications. This might lead to a delayed activation of the passenger airbag for an "unbelted 5th percentile adult female" in the event of a crash thereby increasing the risk of injury for the front passenger. An authorized Mercedes-Benz dealer will update the airbag control unit software for the affected vehicles.
