BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: C1345/66: 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 the difference in each individual part such as the stroke sensor, actuator solenoids, and stroke simulator solenoid. Perform initialization of linear solenoid valve and calibration if these parts are replaced.
The skid control ECU receives shift position P signals from the HV control ECU through CAN communication system.
The DTCs are cancelled when the result of linear valve offset learning is normal.






INSPECTION PROCEDURE
NOTE: When replacing the brake actuator assembly, perform initialization of linear solenoid valve and calibration .

PROCEDURE

1. CHECK DTC
(a) Clear the DTC .
(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:






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) Perform initialization of the linear solenoid valve and calibration .
NEXT -- Continue to next step.
3. RECONFIRM DTC
(a) Turn the power switch off.
(b) Clear the DTC .
(c) Turn the power switch on (IG).
(d) Check if the same DTC is recorded .
Result:






B -- REPLACE SKID CONTROL ECU
A -- END
