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 ignition off and maintain condition for approx. 3 s.
―  Set the vehicle wheels straight-ahead.
―  Switch the ignition ON (engine 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.
