Service bulletin SSM73402

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.

The Diagnostic Trouble Codes (DTCs) B1A75-11 Fuel Sender 1 or B1A76-11 Fuel Sender 2 or both, will be present in the Body Control Module (BCM) if the concern appears. If the vehicle ignition is switched off for a period of time between 2 seconds and 2 minutes and then back on again, the fuel gauge reading will return to normal. The concern affects 17MY only.
