Application

What you need to know (please read before ordering)

Important: We strongly recommend that you replace the AOC feed pump, filter, and oil prior to installing the remanufactured DEM. A clogged AOC filter will over-current the pump and that will short internally, and subsequently destroy, your newly refurbished DEM.

Please Note: 2003 and newer DEMs suffer from a variety of failures from communication issues to total network shutdown. They are also prone to water damage, resulting in an even broader range of failures. In some extreme cases a regular repair may not be sufficient, and extra costs may be incurred in order to get a good working module back to you. This will only be done if a repair isn’t possible, and you will be notified of this before we proceed with other options. Please contact our sales department if you’d like more information.

Please Note: In 2005 and newer models it is also possible for the Rear Electronic Module (REM) to cut off power supply to the DEM. We recommend that you consult our DEM Diagnostic Flow Charts to correctly diagnose the failure.

This is a Repair Service of your existing module. You will need to remove and send your module to us for repair using the shipping labels provided to you.

If you don’t see shipping labels within 1 hour of submitting your order (during business hours) please first check your junk/spam folders. If you still don’t see the labels, please contact us at 1-888-712-2525

Features:

Plug & Play: The software and settings will not be modified, making this module plug and play. No software reload or calibration is required after installation.

Quick Turnaround: Your module will be tested, repaired, tested again, and sent back to you in the same day (unless otherwise noted).

Water-Proof Housing: The DEM housing is permanently sealed with high grade sealant to help prevent any future water intrusion.

Protective Circuit Board Coating: The internal circuit board is coated with conformal coating for additional protection.

Completely reworked PCB: All internal circuit boards are tested at the component level. Any known prone-to-failure parts that are close to the maximum tolerance are automatically replaced.

Quality Tested: All our Volvo DEMs undergo rigorous tests on our specialized custom built CAN-bus driven test bed. All functions, DTCs, and software are checked and verified for proper operation.

Heat Shield is available: To prevent the DEM from heat damage from the nearby exhaust pipe, we recommend that you purchase the optional heat shield.

FAQ

I have been told by my Repair Shop of the importance of replacing the pump and filter when replacing the DEM
Yes we strongly recommend that the pump and filter are replaced whenever the Differential Electronic Module (DEM) is remanufactured or replaced. It is very common for the filter to clog up and overwork the pump. The pump will then short circuit and destroys your newly rebuilt DEM instantly. This is why we are offering these parts in addition to the DEM repair. Please refer to our DEM diagnostic flow chart where you can find detailed information on how to test the AWD pump for proper operation.

What’s the advantage to purchasing the cover kit you carry for the Volvo DEMs?
The DEM is exposed to heat and water due to the location of the unit directly under the car. To avoid having to replace this unit or sending it in for repair, we recommend that you protect this important electrical component with a custom protective shield by IPD.
