Good Day

I would like to know where to start looking for this problem.

"No voltage at ECU Pin 1 when Ignition on"

I have all sort of funny problems with my Rangie and would also like to know if this can be related.

Which ECU are you talking about. Also the model of Range Rover would be useful.

Check Fuses nos. 3 & 7 located on the becm...located below drivers seat. Remove "Trap door" for access.

Just had a look and both fuses are 100%.

Any other places to look?

You can check the connections to the gearbox and shift mechanism in case something worked loose when you revved it.
You could also check the header plug to the gearbox ecu.

I will have a look. thing is when I revved the Rangie, things seems to better...

Could this be a problem when the fuse box under bonnet has gone, or burn marks on it.

Ja Boet,so maak mens!

You also mentioned you have "odd things happening" with your RR.This is indicative of 1) Defective battery/charging circuit
2) " fusebox under bonnet
3) " earth point/battery/alternator cables.
These vehicles are very senstive to the above and can generated odd problems ,including odd random fault codes of which your code may be a symptom.
If you dont have "Rave" ,do a search for "greenoval" and download from that site.This will give you the info regarding Ground points etc.

More Oom JohnP38

I just spoke to Rover Land in SA, and according to him, the message is related to the Pin 1 in the ABS Accumulator Switch.

I do not know where this switch is..... :-(

He also mentioned that with the gears jumping up and down could be the Selector switch on the gearbox.
