Keyless Entry Indicator(s)

When the voltage of the keyless entry transmitter (key fob) battery falls below 2.2 volts, the transmitter sends a low battery signal to the Remote Control Door Lock Receiver (RCDLR). The low battery signal is sent every time the transmitter is used for any remote keyless function. The RCDLR communicates the low battery messages to the Body Control Module (BCM). When the BCM receives three consecutive low battery messages from the RCDLR, the BCM sends a class 2 message to the Instrument Panel Cluster (IPC). The IPC illuminates the key fob battery low indicator in the message center whenever the ignition is ON. The indicator remains illuminated until a transmitter with a good battery (2.2 volts or greater) is used to perform any remote function. When the indicator is illuminated and a transmitter with a weak battery is used to perform any remote function, the indicator turns off for approximately 2 seconds and then turns back on.
