Steering Angle Sensor Initialization Procedure
Warning
• Unless the initialization procedure of the steering angle sensor is completed, the DSC will not
operate, causing an unexpected accident. Therefore, always perform the initialization procedure to
ensure DSC operation if the power supply to the BCM has been cut off due to disconnection of the
BCM connector or negative battery cable, or any other cause.
Caution
• The steering angle sensor initialization value of the BCM is stored using the battery power supply.
Therefore, the battery power supply of the BCM is cut and the stored steering angle initialization
value is cleared when any of the following items are performed.
— Negative battery cable disconnection
— BCM connector disconnection
— Steering angle sensor connector disconnection
— Fuse (ROOM) removal
— Wiring harness disconnection between battery, BCM connector, steering angle sensor
connector
• If the initialization procedure for the steering angle sensor has not been performed, when the
ignition switch is turned to the ON position, the DSC indicator light illuminates and the TCS OFF
light flashes to warn of a malfunction.
1. When replacing or removing the following parts, perform the initialization procedure. (See 09-40-8 STEERING
ANGLE SENSOR INITIALIZATION PROCEDURE.)
• Negative battery cable disconnection
• BCM connector disconnection
• Steering angle sensor connector disconnection
• Fuse (ROOM) removal
• Wiring harness disconnection between battery, BCM connector, steering angle sensor connector
