DTC C1851 LOW PRESSURE MALFUNCTION IN UPSIDE OF KDSS SYSTEM

CIRCUIT DESCRIPTION

DTC Detecting 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.
