## 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.
