NO.6 RSC OPERATES FREQUENTLY/RSC DOES NOT WORK CORRECTLY [DSC/RSC]

id0403b3815900

6 | RSC *operates frequently/RSC* does not work correctly *: DSC/RSC system contains roll stability control function; DSC indicator light illuminates and goes out and while DSC/RSC is operating.
Possible cause | • DSC/RSC HU/CM detected malfunction (input and out put devise malfunction) • Poor installation of SAS control module and/or steering angel sensor (If any of the above sensors are poorly installed, DSC/RSC may operate intermittently) • When replacing the DSC/RSC HU/CM, or SAS control module, initialization is not performed (If initialization is not performed correctly, DSC/RSC may not work correctly) • Tire problem (low or high air pressure, excessive tire wear, different grip level for four wheels) • Poor installation or malfunction suspension parts (shock absorber, stabilizer) • Communication error between DSC/RSC HU/CM and SAS control module (CAN-2 signal)

Diagnostic Procedure

STEP | INSPECTION | ACTION
1 | INSPECT DTC IN DSC/RSC HU/CM AND SAS CONTROL MODULE FOR DTCs • Inspect DTC for the ON-BOARD DIAGNOSTIC SYSTEM. (See ON-BOARD DIAGNOSIS [DSC/RSC].) (See DTC DISPLAY.) • Have DTCs been stored in memory? | Yes | Perform the applicable DTC inspection (See ON-BOARD DIAGNOSIS [DSC/RSC].) (See DTC TABLE.)
No | Go to the next step.
2 | VERIFY THAT EACH SENSOR IS INSTALLED • Are the SAS control module and steering angle sensor securely installed? | Yes | Go to the next step.
No | Install the suspect sensor securely.
3 | VERIFY EACH SENSOR IS INITIALIZED • Was initialized performed after replacement of the DSC/RSC HU/CM or SAS control module? | Yes | Go to the next step.
No | Perform initialization procedure. (See DSC/RSC SENSOR INITIALIZATION PROCEDURE.)
4 | VERIFY THAT TIRE CONDITION • Verify tire condition for following: ― Air pressure ― Wear ― Grip level (different by four wheels) • Are tires conditions okay? | Yes | Go to the next step.
No | Adjust, repair or replace suspect tire.
5 | VERIFY SUSPENSION PART • Verify vehicle posture. • Is there an inclination in the posture of the vehicle right and left, left and rear? | Yes | Inspect the following suspension part: • Shock absorber • Stabilizer
No | Find malfunctioning part according to “intermittent concern troubleshooting”.
