  • Cornering to left: Changes 0 G-positive
  • Cornering to right: Changes 0 G-negative
Perform the DTC inspection for the SAS control module.
(See DTC INSPECTION [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)] .)
(See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)] .)
LAT_ACCL_R (Raw Value)

P_BRAKE_SW Off/On
  • Parking brake lever released: Off
  • Parking brake lever pulled: On
Inspect the parking brake switch.
(See PARKING BRAKE SWITCH INSPECTION .)

NOTE:
  • Displays in the M-MDS but it does not operate.
PMP_MT_SP
R_GEAR_SW Off/On
  • Except shift/selector lever at R position: Off
  • Shift/selector lever at R position: On
STR_ANG_C (Calculated Value) °
  • Steering wheel in neutral position (not turned): 0°
  • Steering wheel turned to left: Changes 0°-positive
  • Steering wheel turned to right: Changes 0°-negative
    NOTE:
    • Constantly indicates 0° until the steering wheel angle neutral position determination by the DSC HU/CM is completed.
  • The steering wheel angle neutral position determination by the DSC HU/CM is completed when the vehicle is driven in a straight line at a speed of 20 km/h or more for several seconds.
Perform the DTC inspection for the PCM, DSC HU/CM, and EPS CM. If a DTC is displayed after performing the DTC inspection for the PCM, DSC HU/CM, and EPS CM, repair the malfunctioning part according to the applicable DTC troubleshooting.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)
(See EPS CONTROL MODULE INSPECTION .) After performing the DTC inspection, perform the following procedures:
  • Start the engine and drive the vehicle in a straight line at a speed of 20 km/h or more for several seconds.

If an abnormal value is indicated after verifying the value of the STR_ANG_C again, replace the DSC HU/CM.
STR_ANG_R (Raw Value)  
  • Steering wheel position when ignition is switched ON (engine off or on): 0° -
  • Steering wheel turned to left: Changes 0°- positive -
  • Steering wheel turned to right: Changes 0°- negative
    NOTE:
    • The signal displayed in this item is a steering angle (relative angle) signal output from the EPS CM.
Inspect the following PID.
  • STR_ANG
