Service bulletin Atc2405

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This Account Team Coverage is being issued to address sealing robustness on air compressor inlet plumbing on certain X15 engines. This field action provides authorization for certified repair locations to seal the turbocharger inlet to turbocharger adapter with RTV, replace the air compressor inlet plumbing O-rings, replace the hose clamp at the resonator box, if equipped, and recalibrate the ECM which may reduce false occurances of Fault Code 555 and 556. This is an update to a previously submitted communication.
