REAR DIFFERENTIAL REMOVAL/INSTALLATION

id031400800400

Caution

•  Performing the following procedures could cause an open circuit in the rear ABS wheel-speed sensor wiring harness if it is pulled by mistake. Before servicing, disconnect the rear ABS wheel-speed sensor and set it aside so that the wiring harness will not be pulled by mistake.

•  If the characteristic value of a new coupling component is not input to the 4WD control module or the characteristic value is input incorrectly after replacing the coupling component, it could result in the following conditions:

?  The system does not operate normally.

?  A problem with durability of the coupling component occurs.

•  After replacing the coupling component, read out the characteristic value of a new coupling component and write it to the 4WD control module. (See COUPLING COMPONENT CALIBRATION DATA WRITING.)

•  Read out the characteristic value of the coupling component from the label or mark shown in the figure.

Note

•  The 4WD control module stores the characteristic value of the coupling component before replacement.

•  If the characteristic value of a new coupling component is not written, the 4WD control module does not store the value.
