hi..

thank you for asking..

See from manual DC250
Belt Home Position too long

NOTE:

The IBT Steering Motor drives the IBT Steering Cam with the gear. While the IBT Steering Cam rotation range is less than 1 complete round, the Steering Cam rotates more than 1 round in the IBT Steering Motor Component Control. Therefore, remove it when the rotation exceeds the rotation range. This is a normal operation and the step-out sound is not abnormal. An error has occurred if no step-out sound can be heard and the IBT Steering Motor does not operate.

Initial Action
Check the opening/closing of the Front Cover.

Turn the power OFF then ON.

Procedure
Check the Fault History for a Belt Home Position Too Long Fail (042-326 Fault Code).

The Belt Home Position Too Long Fail is the only Fault Code in the Fault List.
