DSC (*2) operates frequently. /DSC does not work correctly.
(*2): DSC indicator light goes on and off while DSC operates.
[TROUBLESHOOTING HINTS]
•  DSC HU/CM detected a malfunction (input and output device malfunction).
•  Poor installation of combined sensor and/or steering angle sensor.
(If any of the above sensors are poorly installed, DSC may operate intermittently.)
•  Initialization was not performed for combined sensor, brake fluid pressure sensor when replacing DSC HU/CM, DSC CM, combined sensor.
(If initialization is not performed correctly, DSC may not work correctly.)

Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT FOR DTCs IN DSC HU/CM
•  Have DTCs been stored in memory?
Yes
Perform the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No
Go to the next step.
2
VERIFY THAT EACH SENSOR IS INSTALLED
•  Are the combined sensor and steering angle sensor securely installed?
Yes
Go to the next step.
No
Install the malfunctioning sensor securely.
*3
VERIFY THAT EACH SENSOR IS INITIALIZED
•  Did each sensor initialize after replacement of DSC HU/CM, DSC CM, combined sensor?
Yes
Find malfunctioning part according to “INTERMITTENT CONCERN TROUBLESHOOTING.”
No
Perform initialization procedure.
(See COMBINED SENSOR INITIALIZATION PROCEDURE.)
(See BRAKE FLUID PRESSURE SENSOR INITIALIZATION PROCEDURE.)
