Charged battery last night and after performing another diagnostic test today using FORScan the results were the same as the last diag test on the picture I uploaded yesterday. Results identified the same issue with DTC (PCM-P0443). Does this mean I need to do a parameter reset on the PCM? If so, do I need two keys to perform the reset or can I just use the one and only key I have?
Like I stated previously, I am no auto-electrician/technician so I am depending on you guys to assist with determining what needs to be done to make sense from the FORScan results. |

Clear fault codes
Carry out parameter reset as you already have a previously programmed key. Note that this is to link the engine computer to the body computer and is assuming your key is already programmed to body computer and working correctly but can sometimes fix a unexpected loss of communication. Rescan for codes again. Unless shorting evap normally doesn’t stop you starting 2 keys will be necessary if you decide to replace the body computer as they then need to be programmed to the replacement body computer followed by a parameter reset again to link it to the engine computer Test for power at fuse 11 at both ends by earthing your test light wire and touching other end of test light on each end of fuse ? Have you had dash out while checking tail lights When you turn ignition switch to the reds is the smart shield light flashing fast |

Still trying to familiarize myself with FORScan app, so not sure how to clear codes and perform parameter reset. In performing a parameter reset, does that reset the BEM or the PCM? Does the AU also have a BCM? |

Does anybody know how to reset the parameters using the FORScan app and OBDLink EX scantool??? I cannot find the instructional procedure anywhere online including the FORScan forum.

iirc. au has different bem to au2 depending on year etc. borrow someone remote and program to your car in case you have a alarm hidden somewhere - will still work ok in there car after |

I'm out West QLD in a small community and I'm the only person with an AUII ute, so won't be able to borrow any remote. My AUII has build date JUL01. I did buy another blank key and remote from Ebay, but the key still needs to be cut when I'm in Rockhampton again. |

Clear the fault code and then remove the fuel cap and see if you still get the fault code with the cap left off. The cap has a one way vent valve that allow air in but no fuel or fumes out (preventing vapour hydrocarbon emissions and reducing the risk of a fire in a rollover or a collision that crushes or dents the tank). It it fails so air cannot get in it will both stop the evap system working correctly (as it won't be able to draw vapours out of the tank and the solenoid won't be able overcome the vacuum in the tank and open) giving an evap fault code and stop the ute starting (as the pump won't be able to overcome the resultant vacuum in what is now a totally sealed tank). The pump will also try and draw air out of the evap line via the vapour separator and carbon canister (opposite direction to normal engine vacuum drawn flow) often eventually killing the solenoid valve or in rare cases even partially collapsing the carbon canister. Probably worth visually checking the carbon canister which is behind splash shield in front of the passengers; side front wheel especially if removing the fuel cap gives a result.

However, each subsequent test I have run since the initial test has less IC & RCM fault codes but the PCM still remains the same. |

Hi. Stop playing with the cannon and go back under the dash and find what you broke while tidying up the wiring there. Have a read of the right section of the workshop manual and finish your diagnostic work first ( http://fordforums.com.au/wsmpub/augx/Part%2015-8.html ) Now that you have power to the fuse box you need to make sure that you have that power getting to the BEM as well as the earths and that all the plugs are fully seated as well as checking the wiring to the TILA around the key barrel in the steering column, this may be at the TILA or at one of the plugs where the wiring meets the column under the dash. Cheers MD

Hi. Going by the symptoms on the first page after work was done under the dash to fix the lights and reading the workshop manual section on the BEM the 3 starts followed by the engine stalling after a few seconds and then nothing indicates either a failure of the TILA to read the chip in the ignition key ( faulty wiring. faulty key reader, faulty key (it still has its chip in it?) or wrong key (not the key from the other ute) ) or failure of the BEM itself (which is why we need to check for power to and earth to the BEM and power from the BEM to see why interior light isn't working for one thing as a guide for what may be wrong). After this it may be a case of getting 2 unique keys made (NOT clones) and having them matched to the BEM. Cheers MD

Iirc = if I remember correctly
Au became smart shield after 6-99 before that it was smart lock which is a different system ie can’t use the bem Did you program remote to your vehicle and try it- reason for this is only incase vehicle has a aftermarket alarm or immobiliser hidden somewhere that activated when you disconnected battery You are not going to start vehicle while smart shield light is flashing- should turn off when ignition is turned on - as mentioned it has a chip in key and key reader around where key goes in - also as mentioned make sure you haven’t mixed up keys from other vehicle Smart shield key will have a slot where key ring goes half way across if genuine key Have you carried out a parameter reset yet ? What was actually wrong with tail lights ? Don’t use forscan myself but does it show any other codes in the pcm ? Do you have power at the green with yellow wire at the interior light?

My first round of no-start issues (significant corrosion in the PCM header pins) was intermittent before total failure.
The second round of no-start issues was corrosion in the multi-way connector under the glovebox. Both were caused by leaks at the nearside top of the windscreen. Hence I suggest physical inspection of both the plug under the glovebox and the PCM header plug. Verdigris incidentally highlights the corroded pins.

That connector affects dialogue with the PCM (including immobilisation), it bridges to the PCM and engine harness - hence why I suggested checking it.

Sorry guys, but I had to take an unexpected trip and have now returned. Still not getting anywhere with this bloody ute, so I'm clueless as to what the problem is. I have followed advice/instructions and don't seem to be getting anywhere.
How do check if I am getting power to the BEM? Which coloured wire/s is/are positive to the the BEM? What is A12? After switching over the interior fuse panels again, I am still getting the same DTC's for the PCM (as pictured). By the way, thanks for all previous comments and suggestions from you guys regarding this nightmare. Much appreciated!!! Last edited by FuriousFord; 30-04-2021 at 02:51 PM. |

Yeah checked chose connectors Citroënbender and there's no corrosion evident. Only some residual dust (pins are clean though), but gave it a light blow with air gun before reconnecting.

What would happen if I left the keys in the on position whilst trying to remove the rear demister relay from the interior fuse panel, cause I'm quite sure that's what happened before the smartshield kicked in? I recall seeing the rear demister light on the dash light a couple of times whilst trying to remove the relay. Would that affect the BEM or PCM or both???

What’s puzzling me is your fault codes are typical of restricted/poor dialogue between the PCM and BEM. The theft detection one is a good example, it can be generated by (for example) having the car on reds and key reader not talking, then bridging the starter relay.
Is the block connector to the engine harness, near the washer bottle, fully seated home? |

Yes the block connector is fully seated and I have never touched the connector either before or after the smartshield had activated.

Service (spanner icon) in forscan -> PATS programming.
https://forscan.org/forum/viewtopic.php?f=5&t=836 The software will walk you through the steps You do need two different transponder keys to perform a PATS reset/paramter reset. You can use the uncut blank as a second key, but it is fiddly. When the software asks for the second key, wrap tin foil around the first key's head and hold the second key head up next to the first key. This blocks the first key's transponder signal so the car will see the second key. |

Firstly, initially I only had one key so I ordered another blank one and remote from Ebay. The second key still needs to be cut, but won't happen until I'm in town again as we got no services like that out bush. The next issue is that the PATS programming option is not displayed/available after I run a diagnostic test using FORScan. The only FORScan option available in Services Procedure (spanner icon) is PCM (Reset all adaptions). No other modules are displayed. However, when I reinstalled the interior fuse panel from the AUI ute I have here and ran the diagnostics on that ute, the PATS Programming module and ABS Service Bleed module where available (including PCM (Reset all adaptions)). So I don't understand why PATS Programming option is not available when running diagnostics on my AUII ute. The ABS Bleed module comes up because the AUI ute has ABS and the AUII ute doesn't. Given the above, I now need to know why the PATS Programming service module is not displayed/available when I run diagnostics using FORScan!!! Last edited by FuriousFord; 02-05-2021 at 02:35 PM. |

I think we are getting closer. There seems to be a dialogue problem.
If you can “see” the BEM in ForScan try some actuator tests, from memory there is a menu of functions you can drive from the tester. |
