FUNCTION - Self-Diagnosis / Forward and Reverse Synchromesh Changeover System

A self-diagnostic function has been programmed into the ECU. Seven circuits can be checked for possible faults using the N-CVT warning light to access the problem area. Consult can also be used for diagnostics. Refer to the Trouble Diagnosis section for diagnostic procedures.

A synchromesh changeover system allows for forward to reverse shifting, at the same time eliminating "shift squeak" (occurs when the belt tries to reverse direction very quickly.)

The synchroniser sleeve is central on the hub, and no power is transmitted.

The synchroniser sleeve shifts to the right. Power is transmitted through the hub to the primary (input) pulley.

The synchroniser sleeve shifts to the left. Power is transmitted through the reverse idler gear and counter gear to the primary pulley.

The synchroniser sleeve remains at the reverse position. The park rod and cam engage the park pawl with the park gear. The output shaft is mechanically locked.
