That B1B70-81 (28) again!

I know that B1B70-81 (28) DTC is generally regarded as ignorable but if it suddenly appears there MUST be a reason, surely?
Land Rover didn't put it there for the fun of it!
So what is giving this DTC?
I don't believe that someone on this forum, with a far better brain than me, hasn't worked out what causes it.

Its the "FSOS" code

I’ve got this as well.

Been reading tsb LA418-093 and this would ‘suggest’ the fault is a ‘hard fault’.

What other faults you got showing up?

Mine are

Quote:
Body Control

B1B70-81 (28) Local interconnection network bus circuit 2 - Bus signal/message failure - invalid serial data received
( at 94821 mi )
B1C62-12 (28) Battery saver relay output circuit - General electrical failure - circuit short to battery
( at 94846 mi )


Engine TDV6

P0402-00 (68) Exhaust gas recirculation flow excessive detected
P0578-00 (28) Speed control multi-function input A circuit is stuck


Traffic Message

B1A56-18 (2F) Antenna circuit - General electrical failure - circuit current below threshold


Any correlation?
