Media Control Unit - Remove And Install: Installation

Installation procedure is the reverse of removal, except for the following:

CAUTION: Identify an MCU with LTE modem. Look for ALS3-E or ALS3-US in cell_model, this can be read without removing the MCU.

CAUTION: Do not install used MCUs that have not been remanufactured for diagnostic purposes. Installing a used, non-remanufactured MCU might result in corrupted odometer readings.

CAUTION: North American vehicles with LTE: Put on an ESD wrist strap and connect it to chassis ground before connecting the electrical connectors to the rear of the MCU. Do not remove the ESD wrist strap until the screws (x4) that secure the MCU to the IP carrier have been installed.

If washers were installed behind the touchscreen surround trim on the top 2 screws that secure the touch screen to the IP carrier, reinstall 1 washer on the on the driver's side screw, and 2 washers on the passenger's side screw.
Reinstalling the top pad requires two technicians: One technician presses down on the LH side of the top pad to secure the LH clips while the other technician presses down on the RH side to secure the RH clips. Work from the outer edges of the top pad inward and secure all clips.
