Connect your laptop to the Internet and run the pscan software. It will automatically update itself.

You don't need the interface box or a connection to a car to do this.

If you have not installed the pscan software at all please follow these instructions https://pscan.uk/install/

The only exception is if you are running the old pscan.eu software from a few years ago, that will not automatically upgrade. If you have this then please reinstall from the above link.

Version 0436 is here .

This is a tweak to the 5AS protocol to make it more reliable.

The previous version is here .

I believe that this is fixed in version 0436.
The customer who made the complaint has not been able to try it out.
In our lab environment it now appears to be reliable.

If you sell your pscan on and the new owners laptop requires your old one to be deregistered, then they will be able to do it themselves.
You don't need to do anything.
The new owner inherits the support rights that you got as the original buyer, and, if they have any problems with laptop registration they can contact us and we will help them.
This is a 100% guarantee, and you can point any prospective buyer at this topic to prove that they will be supported.

I am also fine with you advertising your pscan for sale here on this forum if you want to.

I have had a complaint from a customer that they were not able to get their 5AS into learning mode to code in fobs.
This morning I replicated the issue "on the bench" and I can confirm that currently the feature is not reliable.
I was able to occasionally get into learning mode by trying repeatedly, so if anyone urgently needs to code fobs into a 5AS it maybe be worth trying over and over until it works.
I will figure out what the problem is and release an update once it's solved.

Error $22 is defined in the protocol standards as "prerequisite conditions are not met". It basically means that pscan is asking the ECU to reset its error codes but the ECU is refusing for some reason.
The exact logic of why the ECU is refusing is only known the MG Rover engineers who wrote the code inside the ECU.
My guess is that the ECU is still seeing an actual permanent fault with a sensor.
Another reason could be that the engine is running when you erase the errors.

Any feature in pscan that actually changes the vehicle (apart from erasing error codes) comes with appropriate warnings and it will ask you to press the button again (as in, are you really sure?).
Provided that you don't ignore warnings, and if there is a warning that you don't like the look of just press "cancel" or "back", you won't do any harm; so just click on stuff and don't worry too much about experimenting a little.
For your log file just create a new folder/directory somewhere in your harddrive and save the log files in the new folder/directory.

The primary purpose of that button is to log live data.
The idea is that you can start logging something, drive around for a bit, and then view the sensor data with a spreadsheet program and graph it as well if you want.

The features of the 5AS alarm system that pscan has are described here:-
https://pscan.uk/features/5as.html

The factory MG Rover tool may support a few more things but it has been a long time since I have compared the two. These alarm modules are pretty basic, it may not support what you are look for at all.
