Hi, i have news today we checked with the computer, the man told me to change my canister valve and my A/C pressure switch and everything will be fine
I had absolutely the same problem with P0443 and P0645 codes. It is the problem of MC33888FB IC Driver inside PCM. Just need to replace it.
Hello thanks a lot for your answer !
I also diagnosed a faulty pcm but didn't know what was faulty in the pcm.
On your picture you made few lines, wich is the one to replace

Yes. This IC Driver is responsable for A/C Clutch Relay by low side (LS6 pin) and "3 in 1" channels by high side for EVAP Valve.
Resoldering is difficult because the electric board is glued on aluminium plate.

Amazing you found that, I will try to find someone who could change it for me, do you have a website where I can buy it ?
Is it easy to open the PCM ? How did you open ?

Ok. Try to open PCM:
1) Unbend 8 aluminium hooks from face side of PCM;
2) Carefully input plastic blade in joint between top and bottom parts of aluminium case of PCM and carefully cut sealant by all sides. It has strong black sealant (look at my photo in post #27).
The best way for resoldering is help of computer matherboards repair specialist or company. Soldering station and Rose's alloy are needed.
You can buy Freescale MC33888FB from Digikey/RS-Components sites or Aliexpress (from China).

Do you know what is the reference 04 832512AF and KKBT02 on the ship ?
Wich jeep Do you have im wondering if it is the same pcm as me
"04 832512AF" I think it is a local manufacturer code. "KKBT02" usually it is code of date and factory production.
