AWD diconnected service required

GJB · Sep 3rd, 2013, 08:49

Have got the yellow triangle with message AWD DISCONNECTED SERVICE REQUIRED on MY 2010 XC90 R design anybody out there had the same and what was the outcome?

No one else seems to want to answer so I'll give it a try.

The AWD system relies on other systems. So, for example, if the ABS sytem was faulty, the AWD system would not work and would therefore be turned off(disconnected).

You most likely have a fault else where on a related system that is causing this problem.

You could do with codes being read, if you do get them read make sure you ask for them so you can post them up.

I've no idea at this stage what is wrong but what I can tell you is your Haldex system (4 wheel drive system) is reporting an error and as such the car has given you the yellow triangle and the system message. It will also mean it has stopped your 4 wheel drive part from working too.

Unfortunately you really do need the codes to find out what is wrong.

Have now had the codes read and the DEM that supplies power to the AWD has failed

Shadeyman · Sep 9th, 2013, 22:51

What was the codes ?

DEM = Differential Electronic Module. Not heard of that failing before ...

SonyVaio · Sep 9th, 2013, 23:03

Did you get the actual code?

What code reader is being used? Some generic ones are pretty bad at actually pin pointing the problem on the XC90 for haldex codes.

From the invoice following VIDA NO PUMP OUTPUT FROM DEM OIL PUMP READING 4MA CONS DTC DEM-000E PUMP MOTOR
Also contacted dealer and was told they would have to remove prop shaft to gain access.

The DEM is located at the end of the propshaft, there's no need to remove it, access to the DEM doesn't require removal of the proshaft. Must be the motor they plan to replace.

Here, check out this video, you can see the position of the DEM.

+ YouTube Video

EDIT.

I'm unable to find that fault code - DEM-000E.

Can only find these DEM related codes.

DEM-0001 Temperature sensor. Faulty signal
DEM-0002 Pressure sensor. Faulty signal
DEM-0003 System voltage. Faulty voltage
DEM-0005 Control valve. Faulty signal
DEM-0005 Control valve. Internal fault
DEM-0006 Masterpump Faulty signal
DEM-0007 Hydraulic pressure. Incorrect value
DEM-0008 Control module calibration fault. Internal fault
DEM-0008 Control module, calibration fault. Internal fault
DEM-0008 Control module. Internal fault
DEM-0009 Control module Analog/Digital converter. Internal fault
DEM-0009 Control module. Internal fault
DEM-000A Power supply. Faulty voltage
DEM-000A Power supply. Incorrect value
DEM-000C Control module. Faulty hardware
DEM-E000 Control module communication. Faulty communication(unless its this one)
DEM-E003 Configuration fault. Faulty configuration
