Rear Differential Removal/Installation (Us): Notes

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

Oil and Chemical Type

Sealant

Type: TB1217C or equivalent

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 PCM 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 PCM. (See COUPLING COMPONENT CALIBRATION DATA WRITING .)
Read out the characteristic value of the coupling component from the label or mark shown in the illustration.
