SummaryDue 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.
