DTC C1851/51 Low Pressure Malfunction in Upside of KDSS System

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 light 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.

INSPECTION PROCEDURE

HINT:
- When these DTCs are output, perform the hydraulic circuit inspection first by following "HOW TO PROCEED WITH TROUBLESHOOTING".
- If the DTCs cannot be erased even after the hydraulic circuit inspection, perform the electrical circuit inspection by following the procedures.
- Start the inspection from step 1 when using the intelligent tester, and start from step 2 when not using the intelligent tester.
