Welcome.
A bit more info, please?
Gems or Bosch?
Where on the planet are you?
You replaced the TPS? you possibly meant CPS, since this could be letting you down.
Gearbox fault is typically a battery voltage issue.....I know, you replaced it. Now go clean and tighten ALL of the main battery leads. Then get it tested, as there are a lot of dodgy batteries out there.
Did you get the correct fuse box for yours? 2000 was a transition period, and I seem to recall there were 2 for gems and one for Bosch. Is the new one the EXACT same part number?
Next, You have a working fob or 2?
If not, it will immobilise itself with unwanted consequences.......
Get a copy of RAVE.
GET A new mechanic, as yours is a hack.
Look forward to hearing responses.

Thanks annette, I was not sure what the codes were, as I have Both FMII and Nano, I get the info in plain Engrish........Must be a GEMS as an Bosh will not even crank.....
This is why I mentioned the fob, as you have somehow immobilised yourself.
The truck is assuming it is being stolen.
Gallon J. As annette says, DO NOT try the "Remove battery cable, put in Pos II and replace batt cable", or anything other than the EKA.
IF it has EKA enabled, it is ~Probably~ 1515 as this seems to be default for NAS....Of course, we have no idea whatsoever where you are, so this may be invalid....
If you are lucky, that will get things going.
Above all.......Don't panic!..... You are are the bottom of the P-38 learning curve, and we are here to help........

A bit of bad news on the key fobs from dealers.
There are no individual NAS fobs available in the US, I will speculate this applies to Canada as well.
There are now 2 ways to get a working fob.
It turns out you can still buy a Kit with all locks and 2 fobs for about a grand from the dealer.
Plan B is to have Annette, Scotty, or Marty reprogram a fob to work with your Becm.
I believe the caveat with this technique is that the donor fob needs to be from a known Becm, as in they need to read the code for the fob from the Becm it was matched to? (I may be wrong about that bit)

As I said in an earlier post, just because a battery is "New" does not make it "Good". Spontaneous Gearbox fault is 100% voltage related. You either have a bad battery or a loose / corroded connection. Check all main cables. Have the battery tested. A corroded electrical connection, either B+ or earth will admit any number of Gremlins!8-0=
And, yes you would want a Crank Position Sensor, Not a Throttle Position Sensor as a bad CPS will give you the symptoms you are getting.
Also, just turn on the ignition and reset the sunroof, and windows:
Roll one down and hold button for a couple of seconds, then roll it back up and hold the button until the dash says "Window Set". Sunroof the same way and do not forget the sunroof is a 2 way device. This will clear the messages that may be blocking something important.

Also, and this is important for us all to bear in mind: The hack mechanic has broken something, and then been in to the centre console guts to boodge a fix of some sort. We are probably dealing with multiple problems at this point......Just sayin'

Annette, I understand where you are going with this test, however It sound's like you are asking him to connect 12 volts to the Hall effect circuit? then read the signal generated by a spinning piece of metal on what, exactly?
Sound's like an oscilloscope job......Possibly some clarification on this?

Fobs...You can buy them from LR UK
As to the signal.. sure a primitive oscilloscope does the job, I have an old Metex multimeter that does the trick.

Also you can do it with the frequency option on your multimeter.


Frankly.. I guess it is time somebody looks at that BECM

On the fob issue, yes, you may be able to get them from the UK. Unfortunately, they will not be on the correct frequency for NAS systems.
I have a old friend who is a master parts man for pretty much all old British motors, and he scoured the Land Rover North America parts system to see if there were any more NAS fobs out there. No single fobs available, just the aforementioned full lock and key kits, which for a grand, if you needed new locks and had no fobs, are not that bad a deal...............

Anyone out there who knows of any new NAS fobs out there in the distribution chain? I could use a second one for mine

Got it on the CPS test, it's just that most folks have never used the frequency function of their multi-meter, assuming they have one.
I am lucky, I can use the venerable Fluke Scope-meter......

Possibly, a more detailed description of your test procedure for those who have never done this?
Cheers!

Regarding fobs.
OK here is the good news.. any key for Central america will do for you, same frequency as up north.
I will have a look around

As I could order them from Bearmach for my clients I am sure there is a way.

Now that is a very interesting angle!!
Had not thought to check South of the border for fobs.
Please let me know what you find out. I am sure others will be interested to know as well.
Cheers!
