STEERING ANGLE SENSOR FUNCTION
CHU041566120S01
• The steering angle sensor, located on the combination switch, detects the steering angle degree and the
neutral position, and transmits these to the DSC HU/CM via CAN lines.
Warning
• The following circumstances will cause the stored initialization value of the steering angle sensor
to be cleared. This may possibly cause an accident due to the DSC becoming inoperative. Always
refer to the Workshop Manual and properly perform the initialization procedure for the steering
angle sensor so that the DSC operates properly.
— Negative battery cable disconnected
— Steering angle sensor connector disconnected
Note
• 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 DSC OFF light flashes to
warn of a malfunction.

STEERING ANGLE SENSOR CONSTRUCTION
CHU041566120S02
• The steering angle sensor, integrated with the combination switch body, has a sensor unit straddling a disc that
moves together with the steering mechanism. Therefore, if there is any malfunction of the steering angle
sensor, replace the combination switch body.

DSC INDICATOR LIGHT FUNCTION
CHU041555430S01
• The DSC indicator light, built into the instrument cluster, informs the driver of the following vehicle conditions.
— DSC is operating (vehicle side-slip)
— TCS is operating (drive wheel slipping)

DSC INDICATOR LIGHT OPERATION
CHU041555430S02
• When the DSC and CAN lines are normal, the DSC indicator light illuminates for approx. 3 s when the ignition
switch is turned to the ON position to check the light function. When the system is malfunctioning, the DSC
indicator light remains illuminated.
• When the DSC or TCS is operating (DSC has not been disabled by pressing the DSC OFF switch), the DSC
indicator light operates as follows:
