## NHTSA's summary

TRANSMISSION \& ENGINE AUTOMATED DATA COLLECTION AND DIAGNOSTIC REPORTING SERVICE INFORMATION To support proper diagnosis and to promote Fixed\-Right\-First\-Time ? Infiniti may review CONSULT\-III plus \(CIII plus\) data relating to vehicle operation and function to help with vehicle diagnosis and diagnostic validation. IMPORTANT: For transmission/engine repair or replacement, retailers are required to connect C\-III plus and perform ?Diagnosis \(All Systems\)?. Performing C\-III plus ?Diagnosis \(All Systems\)? is also required prior to contacting any Infiniti call center \(i.e. TECH\-LINE, PCC, or WCC\) for diagnostic support or claim preauthorization. NOTE: For additional information regarding Automated Vehicle Data Collection, refer to IWBI/18\-019. To support Automated Vehicle Data Collection, your C\-III plus must have the Diagnosis result reporting function\-Setting turned ON. If Diagnosis result reporting function\-Setting is OFF: \- It may cause dealer consideration for Audit or the Anomalous Repair Control \(ARC\) program, where applicable. \- It may result in a repair being non\-warrantable. Refer to the Service Procedure on the next page to confirm your C\-III plus ?Diagnosis result reporting function\-Setting? is turned ON.
