hi,
Please help me because I'm desperate.
Today I tried to update my pcm, my bad, using elm and now the engine can't start.
my car is focus 1.8 tdci, pcm ver. 7M51-12A650-BNA and I made a copy of original firmware
What to do? please help

This is a known problem on some firmwareversions of the 1.8 TDCI which is not related to the ELM327 interface or ELMconfig. A few years ago Ford even released a TSB (technical service bulletin) to all dealers about this problem.

On the affected firmware versions the PATS data is deleted from the PCM during a firmware update. If the PATS data file of the PCM is empty the car will not start. In this case it is nescessary to pair/initialize the PCM with the instrument cluster after a firmware update. This can only be done with a suitable Ford specific diagnostic system which has the ability to program the Coded PATS (immobilizer) system.



At the moment the only thing you can do is find someone (with a Ford specific diagnostic system) who is able to pair/initialize the PATS system of the PCM and instrument cluster.

Have something to contribute?

Hi,

I followed the steps posted here http://s1203.photobu...e35213.jpg.html

by dezwez but the  engine don't start. When I put the ignition on the imobiliser red light is blinking very fast, and it continue to slow down until it stops blinking. The engine malfunction error don't show up anymore. Also, I think that the battery power is down because in elmconfig at pcm button, ignition voltage it appear 10.27 V.
I think the car is bricked and I expect to worst case

JW1982 explained you the case, it seems your case is the same. You need to reprogram PATS immobilizer using IDS/VCM.

Reprogramming the PATS system will only take about 15 to 30 minutes so in my opinion €350,- is way too much.

Based on the average labour costs for diagnostics I think €50,- to €75,- would be a reasonable price.

Hi,

Is there any chance to be my pcm bricked permanently? Today I called at my Ford local dealer and he said that is a possibility.

On the other hand, when I connect the elm to the pcm it read information and there is a DTC error P1622. I think the photo is suggestive.Thank you

DTC code P1622 (Immobilizer ID Does Not Match) means that the PATS data of the PCM and the instrument cluster do not match.


After reprogramming of the PATS system the problem must be solved.

 There is programmes out there that can do this,but now that you can get all the info online on previous MOT's with the current mileage at each mot, clocking could only be done in small amounts as you can easily catch them out

 hmm interesting. The cable sounds really useful, I am going to go for one.

Tezza mentions other software out there. Would it not be possible to reduce mileage with other software for things like services so someone with an expired warranty (based on mileage) then becomes a valid warranty? After their warranty work is complete, they would put the original mileage back in?

This would be considered clocking which is an entirely illegal offence.

 

When servicing a car, one of the checks is the mileage, which is compared against MOT records for the car on the government computers, any difference would raise eyebrows and if sufficient evidence can be seen could result in a prosecution.

What details are you interested in? Today I was at my local dealer and they were able to initialize the PATS system of the PCM and instrument cluster. The total cost was below 80 E including car towing. After the official update I do not feel any noticeable difference in my engine behavior except a smoother acceleration and some improvements of the engine response.

I think he was after how you got it up and running but that explains it :)

 

80 Euros including towing is very good value!
