AutoCodes – Generic – C1342

C1342 Code - Malfunction In Hydraulic System Front Left

Quick Answer

The Skid Control ECU controls braking force according to the hybrid system regenerative braking force and inputs the fluid pressure necessary for operating each wheel cylinder according to the wheel cylinder pressure sensor. Common causes include Fluid leakage, Faulty Brake Actuator Assembly, Brake Actuator Assembly harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1342 Description

The Skid Control ECU controls braking force according to the hybrid system regenerative braking force and inputs the fluid pressure necessary for operating each wheel cylinder according to the wheel cylinder pressure sensor. DTCs may be stored if brake fluid leaks, wheel cylinder vibrates due to uneven wear of the brake disc rotor, or foreign matter enters the solenoid valve. DTCs may be stored if the line pressure drops during air bleeding.

Code Tech Notes

When replacing the brake pads on an ECB (Electronically Controlled Brake) system equipped vehicle, retracting the caliper's piston and installing new brake pads may cause Diagnostic Trouble Codes (DTCs) to set the next time the brake pedal is depressed. Using an OBDII scanner clear the code and test drive vehicle. If the DTC does not return, the repair is complete. If the DTC returns, perform diagnosis as described in the Repair Manual.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the C1342 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
