 Perform the DTC inspection for the DSC HU/CM.
(See DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .)
DSC_OFF_SW Off/On
  • DSC OFF switch is released: Off
  • DSC OFF switch is depressed: On
 Inspect the DSC OFF switch.
(See DSC OFF SWITCH INSPECTION .)
DSC_ST Off/On
  • During DSC OFF mode: Off
  • Other than DSC OFF mode: On
 Perform the DTC inspection for the DSC HU/CM.
(See DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .)
LAT_ACCL_R
(Raw Value)		 G
  • Vehicle stopped or driving at constant speed: 0 G
  • 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)] .)
LON_ACCL_C
(Calculated Value)		 G
  • Vehicle stopped or driving at constant speed: 0 G
  • Vehicle is driving at a acceleration: Changes 0 G- positive
  • Vehicle is driving at a deceleration: 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)] .)
LON_ACCL_R
(Raw Value)
PMP_MT_SP Off/On
  • Pump motor not activated: Off
  • Pump motor activated: On
 Inspect the DSC HU/CM.
(See DSC HU/CM INSPECTION .)
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 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 2.5)] .)
(See DTC INSPECTION [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 control module.
 Inspect the following PID.
  • STR_ANG

(See EPS CONTROL MODULE INSPECTION .)
