Just Bought a IIDBT G3 and it has given me this list of faults...

ATCM Terrain reponse
U0401-94 (2f) invalid data from engine control module- component failure- unexpected operation
U0402-94 (2F) Invalid data from transmission control module - component failure-unexpected operation
U0416-94 (2F) Invalid data from vehicle dynamics control module - component failure- unexpected operation
U0403-94 (2E) Invalid data from transfer case control module - component failure- unexpected operation

PBM Parking Brake
U0401-00 (2b) invalid data from engine control module

PCM Engine TDV8
P0088-00(2F) Fuel rail sysyem/pressure too high.

Any Ideas where to start as I am struggling with this now

Kind regards

Adi

Most of them will be from low battery voltage at some point, delete them all and see what comes back, then you can ignore most of them unless you have a problem that coincides with a fault code...  Pete

Pete. They all come back up

Does it run OK..?

What voltage are you getting with the tool, most look like low voltage issues, the failing battery gets pulled down when you start and sets the faults off....... Pete

It looks like they're all cascade faults from 'P0088-00(2F) Fuel rail system/pressure too high'
That's the one that needs investigating. In the absence of other DTC's for components, then the actual pressure needs to be verified before going b@lls-deep into PCV/VCV checks.
