DTC C1854 HIGH PRESSURE MALFUNCTION IN DOWNSIDE OF KDSS SYSTEM

CIRCUIT DESCRIPTION

DTC Detection Condition:

The accumulator pressure sensor is located in each of the upper and lower chambers of the cylinder. This sensor detects the pressure in the hydraulic circuit and sends a signal to the stabilizer control ECU.

The stabilizer control ECU turns on the KDSS indicator lamp and stops KDSS control when the accumulator pressure sensor detects abnormal pressure in the hydraulic circuit.

HINT: This DTC does not indicate a malfunction in an electrical circuit. This DTC is output when the accumulator pressure sensor detects abnormal pressure in a hydraulic circuit.
