POSSIBLE CAUSE
|
• DSC HU/CM detected malfunction. (Input and output device malfunction)
• Poor installation with SAS control module (yaw rate sensor, low-G sensor) (If SAS control module is poorly installed, DSC may operate intermittently.)
• There is a difference in condition or air pressure between front or rear tires.
• When replacing DSC HU/CM and SAS control module, initialization is not performed. (If initialization is not performed correctly, DSC may not work correctly.)

(See DTC INSPECTION [DSC HU/CM].)
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [DSC HU/CM].)

3
|
VERIFY THAT BRAKE FLUID PRESSURE SENSOR IS INITIALIZED
• Verify that each sensor is initialized.
• Has the initialization for the DSC HU/CM been performed after replacing the DSC HU/CM and the SAS control module?
|
Yes
|
Inspect the tire pressure and condition.
If the tire pressure is incorrect:
• Adjust the tire pressure to the specification
If the tires are worn:
• Replace the tires.
If the tire pressure and condition is normal:
• Found malfunctioning part according to the “INTERMITTENT CONCERN TROUBLESHOOTING”.
|
|
No
|
Perform the initialization procedure.
