- Wireless Transmitter Memory Function does not Operate

DESCRIPTION

With the engine switch off and the driver side door closed, press the M1, M2 or M3 switch and the transmitter's LOCK or UNLOCK switch. The multiplex network body ECU will receive a key recognition code signal through wireless radio waves, and send the key recognition code signal to the position control ECU & switch assembly via the BEAN line. The position control ECU & switch assembly then organizes the key recognition code received from the memory switch and sounds the buzzer (answer back) when the code is registered.
