Speed Signal Circuit |
DESCRIPTION
This circuit sends a signal to the body ECU (main), and then the signal is converted into BEAN signal. Body ECU (main) sends this signal to each ECU in the multiplex communication circuit.
If the body ECU (sub) cannot receive this signal, body ECU (sub) conducts LO function instead of vehicle switching function control (wiper system).
