Checked with mm and a headlight bulb for load. The force sensor is showing 61n with the brake off ( don't know if thats right or not )How have you checked wiring at epb itself? multimeter or a bulb, multimeters can tell lies.
Try a google as when these were new/ish there was some sort of recall where they repaired/modded the epb loom next to the suspension compressor.
Is the load/strain gauge showing a reading on your diag tool? think its located drivers side of the epb unit.
The on/off switch has quite a few wires going to it, so is not just a simple on/off switch, so maybe worth trying that as a cheap start?
Apart from that I cant really help more as mine has been good or 7 years now.
Top tip is every year adjust the handbrake shoes, every 2nd/3rd year take shoes off and clean/grease contact points.
Does your diagnostics allow for a new pad burn procedure?
Lol, I don't even know what that means ,so no.
The diag tool is the icarsoft lr2. It is pretty basic but seems ok for price.

All the wiring checks out at module plug. From what I can see it is still latched but yes it is released, as in not applied. Don't know if emergency release was pulled as it was like this when I got it. Going to check voltage tomorrow when switch is pulled/pushed just to confirm whats going on. Then pull discs off n have a look incase its a stuck cable/shoe.That’s fully released.
Has it had the emergency release pulled, so now needs to relatch (thought they did it automatically) need to check files tomorrow..
But do you have any volts at the electrictrickery plug when you apply?
Has it all been adjusted (cables) correctly when it was replaced? As you asked in other Fred I think, I don’t know if they need coding to vehicle.

I have had stuff from gentleman of salvage before. The repair bloke on ebay sticks some new cogs in motor that cost 20 quid n charges 125 quid for the job.....not sure he repairs anything else on them regarding circuit board or anything.GOS might be better than some random ebay seller

This guy repairs them for 125 quid, https://www.ebay.co.uk/itm/132651421350?hash=item1ee2a40ea6:g:JpQAAOSwIWNg-nhC
Also new I assume copy ones on ebay for 400 quid with cables etc
Yep....all feeds going into the box check out. Lives and earths.Do you have power going to the EPB box? If i remember the L322 (but pretty much same) has 3 live feeds, then the switch stuff.

I can see the switch on my reader when pulled saying on, idle, off so seems to be working OK.Does the actual handbrake switch check out as working?

I haven't checked can bus wires. It is also hard wired from what I have found which should over ride can bus if its not working.Checked the cab bus?
Easy to check using mm check each wire to earth, you want 2.00/2.30 volts ish, actual reading not that crucial so long as you have a reading on both wires.
