id0602a1813400

Note
•  If the PID/data monitor value “STR_ANG” is inspected, perform the following procedure before inspecting.
1.  Switch the ignition to OFF, and maintain this condition for approx. 3 s.
2.  Set the vehicle wheels in the straight-ahead position.
3.  Switch the ignition ON (engine off or on).

STR_AB_EST*1
°
•  Steering wheel in neutral position (not turned): 0°
•  Steered left: Changes to 0°—Positive
•  Steered right: Changes to 0°—Negative
Note
•  The signal displayed in this item is a estimated absolute steering angle signal output.
•  Perform the DTC inspection for the PCM, DSC HU/CM, and EPS control module. If a DTC is displayed after performing the DTC inspection for the PCM, DSC HU/CM, and 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 EPS control module. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)
