STR_AB_EST

°

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 [PCM (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 EPS control module.

  (See ELECTRIC POWER STEERING (EPS) CONTROL MODULE REMOVAL/INSTALLATION.)

• 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).

• Using the M-MDS, verify the STR_ANG operation condition.

• If an abnormal value is indicated after verifying the value of the STR_ANG again, replace the EPS control module.

Changes to 0 °—negative

NOTE:

• The monitor item STR_ANG indicates steering angle (relative angle).

• The monitor item STR_ANG indicates the steering position when the ignition is switched ON as 0 °. Therefore, the steering position when the ignition is switched ON while the steering wheel is being operated is indicated as 0 °. In this case, 0 ° is not indicated even if the steering position is in the straight-ahead position.

• To indicate monitor item STR_ANG as 0 ° when the steering position is in the straight-ahead position, perform the following procedure.

1. Set the steering wheel in the straight-ahead position.

2. Switch the ignition OFF (LOCK) and hold for approx. 2 min.

3. Switch the ignition ON (engine off or on).

• If monitor item STR_ANG is not indicated as 0 °, perform the following procedure.

1. Set the steering wheel in the straight-ahead position.

2. Switch the ignition OFF (LOCK) and hold for approx. 10—30 min.

3. Switch the ignition ON (engine off or on).
