Service bulletin L-18-01-01

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

GEM has released this Team Tip to inform dealers that Digital Wrench now has a new Motor Controller Update procedure. There was a change made to the temp sensor on the GEM motors which requires a specific calibration of the motor controller to function properly, and accurately read the motor’s temperature. This new procedure will walk a dealer through the reflash process, to ensure that the motor controller receives the appropriate calibration.
