CAUTION / NOTICE / HINT

Note:

When replacing the master cylinder solenoid, perform calibration (Click here).

PROCEDURE

  1. RECONFIRM DTC

    Tip:

    These codes are stored when a problem is detected in the master cylinder solenoid.

    The solenoid relay is in the master cylinder solenoid.

    Therefore, solenoid relay circuit inspections and relay unit inspections cannot be performed. Be sure to check if any DTC is output before replacing the master cylinder solenoid.

    1. Clear the DTCs.

      Chassis > ABS/VSC/TRC > Clear DTCs

    2. Drive the vehicle at a speed of approximately 32 km/h (20 mph) or more for 60 seconds or more.

    3. Check if the same DTCs are output.
