Linear Solenoid Valve Offset Malfunction - Electronically Controlled Brake System

BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: C1345/66,C1368/67: Linear Solenoid Valve Offset Learning Undone

DTC C1345/66 - Linear Solenoid Valve Offset Learning Undone

DTC C1368/67 - Linear Solenoid Valve Offset Malfunction

DESCRIPTION

The skid control ECU stores and corrects for individual differences in the stroke sensor, actuator solenoids, and stroke simulator solenoid. Perform initialization of the linear solenoid valve and calibration if any of these parts is replaced.
The skid control ECU receives the shift position P signal from the HV control ECU through the CAN communication system.
The DTCs are cleared when the linear valve offset learning results are normal.

C1345/66 - C1368/67:

INSPECTION PROCEDURE
NOTICE: When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration Initialization.

PROCEDURE

1. CHECK DTC
(a) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.
(b) Turn the power switch off.
(c) Turn the power switch on (IG).
(d) Check that the DTCs (Electronically Controlled Brake and hybrid control system) are recorded.
Result:





HINT: Before carrying out Perform initialization of the linear solenoid valve and calibration, C1203/95 will output.

C -- REPAIR CIRCUIT INDICATED BY OUTPUT DTC
B -- INSPECT HYBRID CONTROL SYSTEM
A -- Continue to next step.
2. PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION
(a) Turn the power switch off.
(b) Perform initialization of the linear solenoid valve and calibration Initialization.
NEXT -- Continue to next step.
3. RECONFIRM DTC
(a) Turn the power switch off.
(b) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.
(c) Turn the power switch on (IG).
(d) Check if the same DTC is recorded Reading and Clearing Diagnostic Trouble Codes.
Result:






B -- REPLACE SKID CONTROL ECU
A -- END
