Service bulletin B611826

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

Due to unfavorable software, the Storage Management Electronics (SME) will not show fault codes that trigger the Malfunction Indicator Lamp (MIL) when performing ISTA Service Function "Display Permanent SAE Fault Codes." As a result, workshops will have to identify SME-specific permanent SAE (emission related) Diagnostic Trouble Codes (DTCs) stored in the vehicle during diagnosis or when preparing a vehicle for a State Emission Inspection and Maintenance through a workaround procedure.
