VDC WARNING LAMP REMAINS ON

Description

INFOID:0000000004212746

The brake ECU communicates with the combination meter with CAN communication via HV ECU. If the ECU

stores a DTC, the VDC warning lamp will come ON.

Diagnosis Procedure

INFOID:0000000004212747

NOTE:

When removing battery, VDC warning lamp turns ON because the stored zero point of steering angle is

erased. In this case, when driving in a straight line at 35 km/h (22 MPH) for 5 seconds or more, zero adjust-

ment completes and VDC warning lamp turns OFF.

CAUTION:

When replacing the brake ECU, perform initialization of linear solenoid valve and calibration.

1.

CHECK CAN COMMUNICATION SYSTEM

Check if the CAN communication system DTC is output.

Result

A

>> GO TO 2.

B

>> Inspect CAN communication system.

2.

INSPECT HV ECU

Perform HV ECU self-diagnosis.
Is the inspection result normal?

YES

>> Repair or replace malfunctioning components.

NO

>> GO TO 3.

3.

CHECK IF BRAKE ECU CONNECTOR IS SECURELY CONNECTED

Check if the brake ECU connector is securely connected.

NOTE:

The connector should be securely connected.
Is the inspection result normal?

YES

>> GO TO 4.
