NOTICE:
When removing the part, turn the ignition switch OFF.
When replacing the steering angle sensor or ECU, make sure to perform steering angle sensor
zero point calibration.
HINT:
Using SST 09843-18020, connect the terminals Tc and E1.
If any abnormality is not found when inspecting parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circuit corresponding the code. For
details of each code, refer to the page under respective ºDTC No.º in the DTC chart.

Fail safe function:
When a failure occurs in the ABS & BA & TRAC & VSC system, the respective warning light (ABS, VSC) is lit and
the operation of ABS & BA & TRAC & VSC is prohibited. In addition to this, when the failure which disables the EBD
operation occurs, the brake warning light is lit as well and the EBD operation is prohibited.Step 2, 5, 8, 9, 11:Diagnostic steps permitting the use of the
