hi
just been through this process; wires ok in the front passenger under carpet loom; ccm module ok. traced the fault to corroded wires under the rear passenger carpet. You need to unwrap the loom and look for three nodes where multiple wires of same colour; red/black, blue/grey and yellow/ green (I think!) are clamped together with a copper collar and sheathed in a rubber cap. There are 11 reb/black wires; 5 blue/grey and 3 yellow/green. The wire had become detached and corroded so I stripped them back to clean wire and reconnected with in their groups, taped them and hey presto!
Take the time to dry out the carpet - it will be saturated underneath. The root cause for all this trouble are the stupid drain bungs under the battery!
Good luck
