id0403b3815800

5 | DSC *operates frequently. /DSC* does not work correctly. *: DSC/RSC system contains dynamic 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 output device malfunction) • Poor installation of SAS control module and/or steering angle 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) • Open or short circuit in wiring harness between DSC/RSC HU/CM and SAS control module (CAN-2 signal)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT DSC/RSC HU/CM AND SAS CONTROL MODULE FOR DTCs • Inspect the DTC for the ON-BOARD DIAGNOSTIC SYSTEM. (See ON-BOARD DIAGNOSIS [DSC/RSC].) (See DTC DISPLAY.) • Have DTCs been recorded 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 sensor securely.
3 | VERIFY THAT EACH SENSOR IS INITIALIZED • Was initialization 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 condition okay? | Yes | Find malfunctioning part according to “INTERMITTENT CONCERN TROUBLESHOOTING”.
No | Adjust, repair or replace tire.
