DTC    C1345/66    Linear Solenoid Valve Offset Learning Undone

DTC    C1368/67    Linear Solenoid Valve Offset Malfunction

for Preparation Click here


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 cancelled when the result of linear valve offset learning is normal.

DTC No.
INF Code

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 (Click here).

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform initialization of linear solenoid valve and calibration (Click here).

1.CHECK DTC

  1. Clear the DTCs (Click here).

  1. Turn the engine switch off.

  1. Turn the engine switch on (IG).

  1. Check that the DTCs (ECB and EFI system) are recorded.

    Result:

    Condition
    		Proceed To

3.RECONFIRM DTC

  1. Clear the DTCs (Click here).

  1. Turn the engine switch on (IG).

  1. Check if the same DTCs are recorded (Click here).

    Result:

    Condition
    		Proceed To
    DTCs (C1345/66 and C1368/67) are not output
    		A
    DTCs (C1345/66 and C1368/67) are output
    		B
