PRECAUTIONS FOR DIAGNOSIS
- Check that a standard steering wheel is installed correctly to the neutral position of the steering column shaft assembly.
- Whenever the system is diagnosed or the electronic controlled 4WD system component is removed and installed, use the M.U.T.-III to check whether a diagnosis code is stored. If a diagnosis code is stored, erase it and then check again whether it is stored.
- Prior to the diagnosis, all the four wheels must be in good condition (correct size, specification, inflation pressure, balance and wear pattern). The electronic controlled 4WD system does not work correctly when a different size wheel or tyre is installed.
- The wheel alignment is correct.
- No modifications to the engine, suspension, or others, which can affect the electronic controlled 4WD system, is implemented.
