C1345

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


DESCRIPTION

The skid control ECU stores and corrects the difference in each individual part such as the stroke sensor, actuator solenoids. Perform initialization of linear solenoid valve and calibration if these parts are replaced.

The DTCs are canceled when the result of linear valve offset learning is normal.





WIRING DIAGRAM

Refer to DTCs C1315/31, C1316/32, C1352/21, C1353/23, C1354/25, C1355/27, C1356/22, C1357/24, C1358/26 and C1359/28 C1315.

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator, perform initialization of linear solenoid valve and calibration Initialization.

PROCEDURE

1. CHECK DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Turn the engine switch off.

(c) Turn the engine switch on (IG).

(d) Check that the DTCs (electronically controlled brake system and SFI system) are recorded.

Result





C -- CHECK FOR CIRCUIT INDICATED BY OUTPUT CODE Electronically Controlled Brake System

B -- GO TO SFI SYSTEM How to Proceed with Troubleshooting
A -- Continue to next step.

2. PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION

(a) Perform initialization of the linear solenoid valve and calibration Initialization.

NEXT -- Continue to next step.

3. RECONFIRM DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Turn the engine switch on (IG).

(c) Check if the same DTCs are recorded Reading and Clearing Diagnostic Trouble Codes.

Result





B -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal

A -- END
