“Check Fuel-Filler Cap” message is displayed in the instrument cluster.
This is caused by improper control software of the PCM.
When the room fuse was first installed during PDI Clean and i-stop is activated, the message ''CHECK FUEL FILLER CAP'' will be display in the instrument cluster for three seconds only one time and no message will return.
To eliminate this concern, the control software of the cars PCM (Powertrain Control Module) has been modified and is performed by Dealer using MDARS Program and Mazda VCM II.
This PCM Update can ONLY be done by your Mazda Dealer during normal servicing.
While this ''Check Fuel-Filler Cap' message is apparently only a one time view in instrument cluster (IC) Mazda recommends that owners complain to their Mazda Dealer so software update will be done.
More than likely there will be other software updates done at the same time, however you MUST Complain to your Service Advisor so your complaint is recorded and acted upon.
Dealer TSB NUMBER: 09-031/22 on August 18th, 2022.
