NO.12 DSC*2 OPERATES FREQUENTLY/DSC DOES NOT WORK CORRECTLY *2 : DSC INDICATOR LIGHT GOES ON AND OUT WHILE DSC OPERATES

B3E040367650W16

12 | 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, 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 DTC Table.)
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, 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.)
