Cheers Phil Do you know how to test the module?

Where's the transfer case control unit on my 2010 range rover vogue 4.4 tdv8?

The connectors on the transfer box?

Spoke to a land rover specialist today and after giving him the diagnostic code he reckons its a broken wire between the transfer box and ecu

OK got a diagnostic check and it threw up a code. P279D-02 four wheel drive range signal circuit general signal failure.

Hi folks Gearbox fault message and special programmes unavailable showing on my range rover vogue 4.4 tdv8 2010. Put in a new battery and alternator is good. Any suggestions? Cheers
