Ithink I might have heard some people say that on some focus cars the PCM is near the battery but I don't know which years and I don't know if which engine it has Geta comprehensive 2007 Ford Focus wiring diagram to help with any electrical issues or modifications. This diagram provides the necessary information for troubleshooting and understanding the wiring system of your 2007 Ford Focus. Find wiring diagrams for various systems such as the engine, transmission, lighting, audio, and more. Ensure a locatedunder the VIN number on the vehicles As-Built Data page be entered. The Vehicle Data is used by the NGS to verify that the As-Built page being used to configure the selected module is actually for the vehicle VIN as recognized by NGS, either as entered by the technician or read from the PCM during the first step. 28528posts · Joined 2008. #3 · Jan 26, 2011. I believe 1998 and newer fords with PATS used PATSII system in which the key memory was stored in the PCM itself and not within a separate module . If you have access to a ford security tool, PATS should be a type E for that system if it's the same on UK models. EnterSecurity Access on the PATS control function module. Select “Ignition Key Code Erase.”. Disconnect Tool and leave key in RUN for 20 seconds. Cycle key 1 to OFF, then RUN, and back to OFF. Cycle key 2 to RUN. Procedure #3. 2 keys required. Cycle key 1 to RUN. Select “Ignition Key Code Erase.”. Icalled FRPP and they confirmed, my VIN matches their system; however, they said the prior COULD have removed the tune.

PCM Power Diode (which, when power is applied, energizes the PCM Power Relay which then supplies power to the parallel fuses F18, F23, and F24. You have an open circuit on the load side of F30. Start by inspecting the fuse's finger contacts for damage or corrosion. Continue on down the line until the open is Octo. #6. time spent investigating my electrical framework (another story), I ran over this force diode in the motor compartment intertwine box. It seems, by all accounts, to be in the circuit that actuates the PCM power transfer (in a similar wire box). I've generally tried diodes by checking the congruity twice ThisECU is a common failure especially for the Ford Focus 1.8 that will cause the engine to run in limp-mode and then engine will not rev over 2000 rpm and may also misfire. Common fault codes are - P0607 & P2110 adDyGw.
