Electronic Control Coupling (Center) Operation Check <Vehicles With S-AWC>
CAUTION:
- Before connecting or disconnecting M.U.T.-III, always turn the ignition switch to the LOCK (OFF) position.
- A tight corner braking phenomenon occurs when the electronic control coupling (Front) fails. Ensure that the electronic control coupling (Front) is in good condition.
- Connect M.U.T.-III to the data link connector (Refer to - Diagnostic Function DIAGNOSTIC FUNCTION ).
- Start the engine.
- Position the steering wheel in a straight ahead direction.
- Execute "Test" (item No. 6 Center coupling operation check) on M.U.T.-III special function to activate the electronic-controlled coupling.NOTE:
- The forced activation (item No. 6 Center coupling operation check) is continued for 1 minute, then it will be cancelled automatically. Also, using the clear key on the M.U.T.-III, the activation can be forcibly cancelled.
- When the functions are suspended by the fail-safe function, the electronic control coupling cannot be forcibly activated.
- Turn the steering wheel 360° or more clockwise or counterclockwise, move the selector lever to the D range (1st), and start the vehicle slowly. The vehicle should hesitate to move. This phenomenon is called as "tight corner braking".NOTE:
- The occurrence level of the body vibration and noise depends on the condition of tires and roads.
- If the tight corner braking does not occur, the system may have abnormality. Check the AWC-ECU.
