STEERING ANGLE DETECTION FUNCTION
id091800691500
• 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.
-
Caution
-
• The following circumstances will cause the steering angle reference point in the BCM to be cleared which may lead to an unexpected accident due to the system becoming inoperative by not having the necessary steering angle information. Always perform the reference point setting for the steering angle sensor while referring to the Workshop Manual and verify that each system is operational.
-
― Negative battery cable disconnected
― Steering angle sensor connector disconnected
― Fuse (ROOM) removed
― Wiring harness between battery and BCM disconnected
-
Note
-
• If the steering angle sensor reference point setting is not performed and the ignition switch is turned to the ON position, the related system warning lights illuminate/flash to indicate a malfunction.
-
― AFS OFF light flashes (With AFS (Adaptive front lighting system))
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.
-
― Switch the ignition to Off
― Fifteen hours have elapsed since the switch the ignition to Off
• If any one of the following operations is performed, the BCM returns to normal control.
-
― Switch the ignition to On
― The key is inserted in the steering lock.
― A door or the liftgate is opened
― The steering wheel is operated
• During sleep control, the power supply voltage to the steering angle sensor becomes intermittent to control power consumption.
-
Caution
-
• If sudden maneuvering is performed during sleep control, the steering angle reference point stored in the BCM could be cleared. This could lead to an unexpected accident due to the system becoming inoperative by not having the necessary steering angle information Always perform the reference point setting for the steering angle sensor while referring to the Workshop Manual and verify that each system is operational.
