  • the control circuit 2 controls the LED 491C by providing a control signal to the LED drive circuit 404C.
  • the control circuit 2 drives the buzzer 491D by providing a control signal to the buzzer drive circuit 404D.
  • the control circuit 2 selects a control pattern corresponding to these electrical devices using the methods described in the first to third embodiments above, and performs control using the selected control pattern. For example, when the control circuit 2 receives a detection signal from the sensor 491B while the right turn indicator is on, it turns on the LED 491C and sounds the buzzer 491D to warn the driver.
  • the first resistance portion is configured to be positioned closer to the ground than the second resistance portion.
  • the second resistance portion may be configured to be positioned closer to the ground than the first resistance portion.
  • the control circuit switches the control pattern of an electrical device connected to a wiring board by a connector as a method for performing control corresponding to a resistance value signal.
  • other methods may be adopted.
  • the in-vehicle control system may be configured such that the control circuit identifies a control pattern corresponding to a resistance value signal, outputs a signal indicating the identified control pattern to an external ECU, and causes the external ECU to perform control according to the control pattern.
  • the configuration in which "the control circuit identifies a control pattern corresponding to a resistance value signal, and outputs a signal indicating the identified control pattern to an external ECU" corresponds to "the configuration in which the control circuit performs control corresponding to a resistance value signal.”
