Normal Operation and Fault Conditions
Vehicle access to a WiFi source - A WiFi hotspot
with a minimum of 3 bars signal strength is strongly recommended at the
location where the vehicle is parked over night, to make sure OTA
updates are completed without delays. To avoid incorrect replacement
of the Gateway Module or other OTA system components, the signal
strength must be verified with the customer prior to repair when OTA
update concerns are being reported.
REFER to: Module Configuration - System Operation and Component
Description (418-01B Module Configuration - Vehicles With: Over-the-Air
(OTA) Programming, Description and Operation).
