Pump Motor Removal

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Some hydraulic fluid will be lost when removing the pump motor assembly.

NOTE:

The Rear Driveline Module (RDM) must be topped off with proper hydraulic fluid if pump motor assembly is being serviced. The hydraulic system then must be bled.

NOTE:

The RDM must be parked prior to removing the pump and motor assembly to properly align the shift fork and shift collar.

CAUTION:

Do not mix hydraulic fluid and the RDM lubricant. Use only recommended fluid to prevent damage to Rear Driveline Module components. Fluid must meet material specification MS-2155.

  1. With the scan tool, run the RDM Bleed to park the RDM. The RDM is in the parked position when the message "The rear differential fluid level can now be topped off, press Continue after filling fluid level" is displayed.
