The door lock control system that is controlled by the body ECU in the MPX consists of the following components:
See “Location” in “Components” for the parts that have the same function in the door lock control system controlled by the integration relay.
1.Body ECU
The body ECU detects the vehicle condition based on the data from each switch, each sensor or through MPX and drives all the door lock control motors with the built-in relay.
2.Driver door ECU
The driver door ECU detects the state of the door lock control switch and key-operated switch of the driver’s door and transmits the signal to the body ECU with the MPX.
3.Front passenger door ECU
The front passenger door ECU detects the state of the door lock control switch and key-operated switch of the front passenger’s door and transmits the signal to the body ECU with the MPX.
4.Meter ECU
The meter ECU calculates the vehicle speed from the vehicle speed pulse signal from the skid control ECU and transmits to the body ECU.
