Hello fellow masochist and enthusiasts! First want to say thanks for all the great info on this site over the years, it’s been extremely helpful. I’ve typically been able to read, search and find similar, if not identical issues to my own, fix based upon the forum recommendations…and in doing so keep this rolling box on the road. What a plush nightmare it has been!
With that said, I have hit a figurative wall. I have the classic lr3 3 amigos HDC Fault , ABS & Amber brake light (wear sensor light I believe), transmission fault, lowered suspension etc etc. It was happening intermittently during the initial system check on startup. It’d fail essentially, id cycle the key off and back on, that would clear it and all was well for a few months until one day they just stayed on.. I read a ton and started by replacing the brake switch under the dash. No help.. so I moved to the battery which was replaced less than 2 years ago, and is stamped July 2021. It reads beautiful voltage both under load and when removed from vehicle, hooked it up for top-off per say and it clears all tests on the battery maintainer, terminal posts and cables are clean, grounds at body on both sides show zero corrosion and are secure and so on. I looked at the transfer case module and all associated wiring in that area, no signs of any corrosion or water. I replaced both brake wear sensors, pulled tail light bulbs, calibrated steering angle sensor, checked fuses in both locations etc… even broke down, bought a diagnostics tool to read the live engine data and any stored codes. Which puts us to current events… plugged it in, went through each selectable module or system and this is what she says:
Abs-
•invalid data received from steering angle sensor
•Invalid data received from rear diff control module
Instrument Pack-
•Lost communication with ride level module
All terrain Control Module-
•invalid data received from vehicle dynamics control module
•invalid data received from transfer case control module
•invalid data received from ride level control module
Ride level control module-
Invalid data received from vehicle dynamics control module
Body control module-
•Passive start ignition relay coil circuit
Rear differential control module-
•clutch position is not learnt
Vehicle dynamics control module-
•Invalid data received from steering angle sensor module
•invalid data received from rear differential control module
I feel like if I read or say the word module one more time my head is going to spontaneously combust. I hate beating a dead horse but I would any help or direction here. Car has been off the road for a month now while I try and figure this out, wait on parts etc.
Thanks in advance
