Technical Service Bulletin G-208451 — 2009 CHEVROLET HHR

14546 - CUSTOMER SATISFACTION PROGRAM. CERTAIN 2009-2010 MODEL YEAR CHEVROLET HHR VEHICLES MAY HAVE A PASSENGER AIR BAG IN-LINE JUMPER WIRING HARNESS CONNECTOR WITH FRETTING CORROSION AT THE TERMINAL CONTACTS. FRETTING CORROSION COULD CAUSE AN INCREASE IN THE SYSTEM DEPLOYMENT LOOP RESISTANCE. THE VEHICLE’S SENSING AND DIAGNOSTIC MODULE MAY INTERPRET THIS INCREASE IN RESISTANCE AS A FAULT WHICH WILL ILLUMINATE THE AIR BAG LIGHT ON THE VEHICLE INSTRUMENT PANEL AND SET DIAGNOSTIC TROUBLE CODES B0019 AND/OR B0020. IF THIS CONDITION IS NOT CORRECTED AND THE RESISTANCE IN THE CONNECTOR REACHES A HIGH ENOUGH LEVEL, THE PASSENGER AIRBAG MAY NOT DEPLOY IN THE EVENT OF A VEHICLE CRASH. DEALERS ARE TO REPLACE THE UNSEALED CONNECTOR WITH A SEALED CONNECTOR.
