PID/Data Monitor Table [Dynamic Stability Control (DSC)]

NOTE:

If the PID "STR_ANG_R" is inspected, perform the following procedure before inspecting.

Switch the ignition to OFF, and maintain this condition for approx. 3 s.
Set the vehicle wheels in the straight-ahead position.
Switch the ignition ON (engine off or on).

Other than TCS OFF mode: On

Perform the DTC inspection for the DSC HU/CM. (See DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .)

LAT_ACCL_R (Raw Value)

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 - MEXICO SPEC.)] .) (See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.)] .)

LON_ACCL_R (Raw Value)

P_BRAKE_SW

Off/On

Electric parking brake is released: OFF
Electric parking brake is applied: ON

Inspect the electric parking brake switch. (See ELECTRIC PARKING BRAKE SWITCH INSPECTION .)

PMP_MT

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

Inspect the PCM. (MTX) (See PCM INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Inspect the TCM. (ATX) (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (FW6A-EL, FW6AX-EL)] .)

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 DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .) (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS [ELECTRIC POWER STEERING (EPS)] .) 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.
