DSC*2 operates frequently/DSC does not work correctly*2: DSC indicator light goes on and off while DSC operates
Possible cause
•  DSC HU/CM DTC is stored
•  Poor installation with SAS control module and/or steering angle sensor
―  If any of the above sensors are poorly installed, DSC may operate intermittently
•  Initialization is not performed after replacing DSC HU/CM or steering angle sensor
―  If initialization is not performed correctly, DSC may not work correctly

Diagnostic procedure

STEP

INSPECTION

ACTION
1
CONFIRM DSC HU/CM DTC
•  Retrieve the DSC HU/CM DTC using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No
Go to the next step.
2
INSPECT INSTALLATION OF SAS CONTROL MODULE AND STEERING ANGLE SENSOR
•  Inspect the installation of SAS control module and steering angle sensor.
•  Are the sensors securely installed?
Yes
Go to the next step.
No
Install the malfunctioning sensor securely.
(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
(See STEERING ANGLE SENSOR REMOVAL/INSTALLATION.)
3
INSPECT INITIALIZATION OF SAS CONTROL MODULE AND STEERING ANGLE SENSOR
•  Did the sensors initialize after replacement of DSC HU/CM or steering angle sensor?
Yes
Found the malfunctioning part according to Intermittent Concern Troubleshooting.
(See PRECAUTION [DYNAMIC STABILITY CONTROL (DSC)].)
No
Perform the initialization procedure.
