Morning,,A friend of mine has just called in with his 2012 RRS AB & its coming up with all terrain fault on dash,,ive just had scanner on it & its coming up with u0434 suspension control module B & c1b03 direction control valve,,before it goes into LR has anyone any idea what needs changing.?

I found this, probably no use at all though, looks like six codes beginning C1B03, common bit seem to be Directional Control Valve 1 Solenoid. Is the other code UO434 or possibly UO43A ?

This could be the other bit.

U043A-68

Invalid Data Received
From Suspension
Control Module "B" -
Event information
The terrain response
switchpack has detected
that the adaptive damping
system control module had
operated in a way or at a
time that it had not been
commanded to operate
The adaptive damping
system control module is
unable to support normal
terrain response
Using the manufacturer approved diagnostic system, check the adaptive damping system control module for
DTCs and refer to the relevant DTC index, rectify as required. Check the system is operating correctly and the
DTC does not return. If the problem persists, suspect the adaptive damping system control module.
