DTC C1831/31 Accumulator Solenoid Malfunction / Upside

DESCRIPTION

DTC Detection Condition:

By receiving signals from the stabilizer control ECU, the accumulator solenoid valve closes to cut the fluid flow to the accumulator (the valve closes when current is applied to the solenoid valve and opens when current is not applied).

The stabilizer control ECU controls the opening/closing of the accumulator solenoid valve based on the vehicle speed, lateral acceleration and steering speed sent from each sensor.
