DTC C1359/28 Rear Decreasing Pressure Solenoid LH Malfunction

DESCRIPTION

DTC Detecting Condition (Part 1):

DTC Detecting Condition (Part 2):

DTC Detecting Condition (Part 3):

Each solenoid adjusts pressure which affects each wheel cylinder according to signals from the skid control ECU and controls the vehicle.

The master cut solenoid (SMC 1/2) is closed and blocks the master cylinder pressure from the Electronically Controlled Brake control pressure when the system is normal. The master cut solenoid is open and sends the master cylinder fluid pressure to the non-assisted brake wheel cylinders during the fail safe due to system malfunction.
