Toyota Yaris: Active Torque Split Awd System / Calibration

NOTICE:

• When the AWD ECU assembly is replaced, before removing the AWD ECU assembly, it is necessary to perform ECU Data Save to save the original AWD ECU assembly information.
• When the AWD ECU assembly is replaced, it is necessary to perform the following in order: ECU Data Initialization and ECU Data Write.
• When the AWD linear solenoid (transmission coupling assembly) is replaced, it is necessary to perform the following in order: ECU Data Initialization and ECU Data Write (when replacing AWD linear solenoid (transmission coupling assembly)).
• When the yaw rate and acceleration sensor (airbag sensor assembly) is replaced, it is necessary to perform ECU Data Initialization. Parts Replacement Compensation Table
