Active Torque Control 4Wd System -- Calibration



DESCRIPTION

  1. When the 4WD control ECU is replaced with a normal one from another vehicle or the yaw rate sensor is replaced, perform calibration.

  2. Follow the chart to perform calibration.

    Part Replaced
    		Necessary Operation
    4WD Control ECU (When replaced with a normal one from another vehicle)
    		Clear zero point calibration data
    Yaw Rate Sensor
    1. Clear zero point calibration data
    2. Perform yaw rate and deceleration sensor zero point calibration

    HINT:
    1. When the 4WD control ECU is replaced with a new one, calibration is unnecessary.
    2. Calibrate the 4WD control ECU by performing calibration of the vehicle stability control system.

PERFORM CALIBRATION (When Using Intelligent Tester)

  1. Clear the zero point calibration data.

    1. Turn the ignition switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the intelligent tester on.

    5. Enter the following menus: Chassis / Four Wheel Drive / Utility / Reset Memory.

    6. Operate the intelligent tester to clear the data.

      NOTICE:
      When the yaw rate sensor is replaced, be sure to also perform vehicle stability control system calibration (RAV4_ACA30 RM000001K1O00SX.html).

PERFORM CALIBRATION (When not Using Intelligent Tester)

  1. Calibrate the 4WD control ECU by performing vehicle stability control system calibration.

    HINT:
    To perform vehicle stability control system calibration, refer to PERFORM ZERO POINT CALIBRATION OF YAW RATE AND DECELERATION SENSOR (When not Using Intelligent Tester) (RAV4_ACA30 RM000001K1O00SX.html).
