# Service bulletin 9100471

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

"CANISTER Vapor \-If an issue is detected with the Evaporative System Integrity Module \(ESIM\) Detector and not the Vapor Canister, only replace the ESIM Detector. \-Before replacing the Vapor Canister due to Hard to Fill condition, replicate the condition at the Gas Station. If the condition is replicated, then check: 1\) for kinked or pinched Clean Air Hose between the ESIM and the EVAP Air Filter; 2\) for plugged EVAP Air Filter; 3\) for kinked or pinched Vapor Hose between the Fuel Tank and the Vapor Canister. If the EVAP Filter is restricted, the replace the Filter. \-Check if the Vapor Canister is flooded with fuel or the Recirculation Line has fuel. If fuel is found in the Vapor Canister or the Recirculation Line, then drop the Fuel Tank, remove the FDM Lock Ring to check if the internal Vapor Line is properly connected to the FDM Port. If the Vapor Line is not connected, then drain the fuel from the internal Vapor Line and properly connect to the FDM. Replace the Vapor Canister and the ESIM."
