Introduction
Some vehicles operated in extremely cold temperatures may exhibit a condition where the Remote Engine Starter (RES) does not function.
Before RES diagnosis confirm with the customer the ambient temperature when the malfunction was experienced.
The RES system was designed to operate at temperatures above -22 F (-30 C). Non-operation of the RES system below this threshold should be
considered a normal condition.
