SRS Module

I have a 2006 TD6, Icarsoft CR Pro shows up a Link Error when trying to connect to SRS and and Land Rover SDD does not recognise the Restraints Control Module. Any advice on where to start looking would be appreciated
The battery was replaced 2 months ago and is fully charged, there is no battery drain

Has the module been replaced at some point?

I do not know, it's not been replaced in the short time I have owned the car

Unless you find the srs ecu and test for ground and live supplies ?
