•  Steering wheel position when main power is switched ON (READY off or on): 0°
•  Steered left: Changes to 0°—Positive
•  Steered right: Changes to 0°—Negative
Note
•  The signal displayed in this item is a steering angle (relative angle) signal.
•  Perform the DTC inspection for the PCM, electronically controlled brake unit, and Electric Power Steering (EPS) control module. If a DTC is displayed after performing the DTC inspection for the PCM, electronically controlled brake unit, and Electric Power Steering (EPS) control module, repair the malfunctioning part according to the applicable DTC troubleshooting.
•  After performing the DTC inspection, perform the following procedures:
―  Switch the main power OFF and maintain condition for approx. 3 s.
―  Set the vehicle wheels straight-ahead.
―  Switch the main power ON (READY off or on).
―  Verify “STR_ANG” operation condition.
•  If an abnormal value is indicated after verifying the value of the “STR_ANG” again, replace the Electric Power Steering (EPS) control module.
