PID/Data Monitor Table [Electric Power Steering (EPS) Control Module]

NOTE:

If the PID/data monitor value "STR_ANG" is inspected, perform the following procedure before inspecting.

Switch the ignition OFF, and maintain this condition forapprox. 3 s.
Set the vehicle wheels in the straight-ahead position.
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. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) (See DTC INSPECTION [DSC HU/CM] .) (See DTC INSPECTION [ELECTRIC POWER STEERING (EPS) CONTROL MODULE] .)
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 .)

STR_ANG

Steering wheel position when ignition is switched ON (engine 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, 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.
