DSC control system

DETECTION CONDITION
|
• DSC control for the front wheels continues for 10 s or more.
• During DSC control, the pressure increase operation to any of the all four wheels does not occur for 1.3 s or more.

POSSIBLE CAUSE
|
• This does not indicate a malfunction since constant control over extended period of time is inhibited to protect the DSC solenoid valve inside the DSC HU.
