  2. Set the vehicle wheels in the straight-ahead position.
  3. Switch the ignition ON (engine off or on).

STR_AB_EST
NOTE:
  • The signal indicated in this item is a steering angle (estimated absolute angle).
 ° Steering wheel position when vehicle wheels straight ahead 0 °
  • 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. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0] .) (See DTC INSPECTION [DSC HU/CM] .) (See DTC INSPECTION [EPS CONTROL MODULE] .)
  • After performing the DTC inspection, perform the following procedures:
    • Switch the ignition off and maintain condition for approx. 3 s.
    • Switch the ignition ON (engine off or on).
    • Set the vehicle wheels straight-ahead, then drive the vehicle straight at 20 km/h {12 mph} or more for 5 s or more.
      • Using the M-MDS, verify the STR_ANG_EST operation condition.
  • If an abnormal value is indicated after verifying the value of the STR_AB_EST ANG again, replace the steering column. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION .)
Steered left Changes to 0 °-positive
Steered right Changes to 0 °-negative
