ELECTRONIC CONTROL COUPLING (CENTRE) OPERATION CHECK <VEHICLES WITH S-AWC>


1.
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 diagnosis connector (Refer to GROUP 00 - Diagnostic Function).
2.Start the engine.
3.Position the steering wheel in a straight ahead direction.
4.Execute "Test" (item No. 6 Centre coupling operation check) on M.U.T.-III special function to activate the electronic-controlled coupling.
note
  • The forced activation (item No. 6 Centre 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.
5.Turn the steering wheel 360° or more clockwise or anti-clockwise, 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 tyres and roads.
  • If the tight corner braking does not occur, the system may have abnormality. Check the AWC-ECU.
