Circuit/System Description

Keyless entry transmitters contain a motion sensor. The BCM monitors the type of motion that the keyless entry transmitter is experiencing and if it is a type of motion consistent with a customer starting or unlocking a vehicle then it will allow the requested function. If the BCM detects motion that is considered inconsistent with a customer starting or unlocking a vehicle then it will not allow the requested function. The purpose of this is to try to prevent unwanted detection of the keyless entry data.
