TechTipTuesday: Differential Electronic Module, Pump and Filter Removal Procedure for Volvo 2003 – 2015

xemodex_dem_removal2

Today we’re featuring a step-by-step tutorial on how to safely remove your Differential Electronic Module (DEM) from your Volvo.

This DEM removal tutorial applies to the following models:
All Volvo Models 2003 – 2015

Common symptoms of a failing DEM include:
2003 and newer DEM’S suffer from a variety of failures from communication issues to total network shutdowns. They are also prone to water damage, resulting in an even broader range of failures. In 2005 and newer models it is also possible for the Rear Electronic Module (REM) to cut off the power supply to the DEM. We strongly recommend that you consult our DEM Diagnostic Flow Charts to correctly diagnose the failure. We also recommend that the Haldex feed pump is tested prior to reinstalling a rebuilt DEM. These pumps can seize-up creating a short circuit. Your freshly rebuilt DEM will be destroyed instantly as a result.
