DTC C1994 [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2802200

DTC | C1994 | DSC control system
DETECTION CONDITION | • During ABS control, there are two ore more wheels which the wheel speed is 10 km/h {6.2 mph} or less when pressure reduction or maintain is continuously requested for 0.3 s—3 s (depending on vehicle driving conditions). • DSC control is performed continuously for 10 s (5 s if the vehicle speed is more than 100 km/h {62.1 mph}).
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.
