Affected Component: ENGINE AND ENGINE COOLING

Summary
Emission Recall - General Motors has decided to conduct a Voluntary Emission Recall involving certain vehicles with a 2.8L diesel engine. The Engine Control Module (ECM) may not properly handle diagnostic information for the exhaust Particulate Matter (PM) sensor. This can prevent the PM sensor signal from being used to diagnose the functionality of other components. Additionally, if a PM sensor fault occurs, it may not result in setting a Diagnostic Trouble Code (DTC) or Malfunction Indicator Lamp (Check Engine Light) illumination. Dealers are to reprogram the ECM.
