Service bulletin M340120

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

SERVICE ACTION - PROGRAM THE BODY DOMAIN CONTROL (BDC) UNIT: Aftermarket scan tools cannot read fault codes in the Dynamic Stability Control (DSC) unit via the On Board Diagnostic (OBD) socket. The DSC data is not processed correctly in the BDC and therefore cannot transmit any diagnostic requests via the OBD using aftermarket scan tools.
