Thank you very much! I will try to find J1850PWM
Why! You are already reading the PWMJ1850 network no need to go and "try to find it"!

You apparently are not understanding that your Mk 1 has no CAN bus. The PWM Network in your module tab is J1850(Ford actually calls it SCP or Standard Control Protocol. The rest of the industry calls it PWMJ1850) and your adapter is reading it just fine as well as reading the ISO network modules according to your screen shots. That is all the modules the car likely has!!!

There is likely not many options that can be changed or enabled in any of those modules

The reported Can error has nothing to do with a CAN network as this car does not have one and the HS/MScan switch is not even needed for this car!

The Can error you are receiving is a network error message that means that Forscan is having to request data multiple times(3% of the data had to be requested multiple times) Data packets from one or more modules is being received with errors or arriving with data missing but subsequent request are receiving the missing data but this error correcting is triggering this error message!

It looks, from your screen shots, like Forscan is getting an acceptable read before the modules are declared AWOL and this network error is most often a problem seen with the lower end cheap adapters!
It can also indicate one or more modules is slow in responding to data queries and had to be woken up with multiple requests before it responded and sent the data.
Again this is most likely an adapter error with slow data queries rather than car network problem even though your getting a good 3 Millisecond test response at the beginning!
This is fine if you are only checking and clearing DTC codes but a detriment for programming of any kind and it can even cause a module self test to fail before it is finished or to stop reading data and dropping out during PID reads!

Because of that error I would not be doing anything involving AsBuilt module configuration with this adapter and Forscan probably will declare it unsuitable for programming!

Thank you guys for detailed explanation and sorry for wasting your time.
If i understand it correctly, there is no way to get to other modules. I bought it because i wanted to get to ESP system/modules, because i have light on and i dont know what it causes.

Come to terms that you have a garbage adapter.
1) There are NO other modules.
2) That Ford does NOT have a CAN system.
3) ESP is diagnosed and tested via ABS.
4) If there is a fault with ESP, then the ABS would record a fault.
5) If it even had ESP (Standard equipment on specific 2.0 Zetec ESP models) maybe?
6) Your scan defines that the ABS is active and diagnosed via ISO protocol.

Now that we all went through this exercise, would it not be prudent to POST the fault codes?
My best guess, the battery was disconnected and something requires an adaptation.
Maybe calibrate the steering angle sensor?

So the possible causes of P1000 could be: battery disconnected - did that few weeks ago and i have been driving a lot.
PCM Diagnostic Trouble Codes (DTC) have recently been cleared with a scan tool - 4 days ago, so maybe this could be the problem

Maybe i should start with things that i have done.
1. ABS-ESP light came on
2. changed ABS/ESP module (numbers are different)
3. ABS light disappeared, ESP still on
My guess was calibrate ESP, but didnt find any information about it.

Could bad alternator start ABS-ESP problems?

I have no fault codes.
I think this too.
I would like to do that, but dont know how.

I will send more pictures tomorrow.

Post the part number of the original ABS.
Post the part number of the replacement ABS.
Ask / request the dealer if that model was built with ESP.

Number of original -2M51-2C405-AG - 99,9% had ESP
Number of new one - 2M51-2C285-BD - ESP light is on - I was told that the module has ESP

AdvanceTrac should be ESP

Call your dealer with the VIN, your part number fits a 2004 Ford Focus.
Your scan device is unreliable and trying to fit an unproven used or a new part.
Is it new or used?
You never posted the ABS original and subsequent strategy from the used version
You never posted the original ABS fault.
You are trying to shove a square peg into a round hole.

It is used.
"You never posted the ABS original and subsequent strategy from the used version" - Dont understand that sorry.
"You never posted the original ABS fault" - I dont know the fault.
"You are trying to shove a square peg into a round hole." - That square peg has the same diagonal as the diameter of the round hole.

My question is: Can FORScan calibrate ESP in ford focus ST170 mk1?

"On the Conduct of the Understanding" ~ Sydney Smith

All four tyres must be the same profile, circumfrence and fitting factory specifications.
The steering wheel angle sensor must react to positive or negative numbers when turning the steering wheel.
The sensor should be close to 0.0 degrees when centered.
The Lateral Acceleration Sensor and the Yaw Sensor must must react when driving the Ford.
If those sensors are NOT present or NOT reacting or NO data, you have the incorrect ABS with ESP.

If the incorrect module is installed, it will never calibrate.
If the incorrect As-Built data does not conform, it will never calibrate.
If the incorrect strategy is programmed, it will never calibrate.

"The sensor should be close to 0.0 degrees when centered." How can i find out and change it?
I did not find any scheme of ESP sensor / module locations
Could the shock absorber be cause?

I will probably take it to Ford dealer.
