STEERING ANGLE DETECTION FUNCTION

id094000103300

• The steering angle is calculated based on the signal from the steering angle sensor and sent to other units via CAN.

Steering Angle Sensor

• The steering angle sensor, located on the combination switch, detects the steering angle and the neutral position, and transmits them to the BCM.

  Note
  • The steering angle reference point stored in the BCM is cleared in the following cases.
    ― Negative battery cable disconnected
    ― Steering angle sensor connector disconnected
    ― Fuse (ROOM) removed
    ― Wiring harness between battery and BCM disconnected

Sleep Control

• When determination is made with all of the following conditions met and no occupants in the vehicle, the BCM initiates sleep control and controls power consumption.

  ― Ignition switch is in the OFF position
  ― Fifteen hours have elapsed since the ignition switch was in the OFF position

• If any one of the following operations is performed, the BCM returns to normal control.

  ― Ignition switch is turned to the ON position.
  ― The key is inserted in the steering lock.
  ― A door or the liftgate is opened

• During sleep control, the power supply voltage to the steering angle sensor becomes intermittent to control power consumption.

  Note
  • If sudden maneuvering is performed during slip control, the steering angle reference point stored in the BCM could be cleared.
