Service bulletin T-TT-0735-23-1

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

TT: When using a Mongoose MFC3 cable to connect for diagnostics to the DLC connector on current generation GR86, the cable may contact the driver?s door panel when closed. Please see attached photos for an example of this condition. It is recommended that an ADVi unit be used for diagnostics or the driver?s door remain open if using a Mongoose MFC3, to prevent any damage to the DLC connector, cable, or door panel.
