Success!
I have just verified in the lab that I can now
(1) enable or disable Cruise Control,
(2) add or remove support for Traction Control in the PCM (If you want to convert from 3Ch to 4Ch ABS that is - requires changing the module and brake lines),
(3) change the wheel/tyre size
(4) Change the axle ratio and
(5) flash your PCM to the latest version while we're at it!
There's even some octane Adjust/Spark-retard setting in there that I can set - which I haven't toyed with for the moment.
If you have a custom tune, however, I can't help. This is all just Factory stuff.
Today is a good day.

congrats.
Can you read the contents of the PCM ?
And can all of the above (with exception to writing I guess) be access with a regular ELM type device. |

On a BA - yes.
On a BF - not yet.
With an ELM. Read as above. Write - not sure if it's fast enough, but with the right software and the FEPS breakout cable I've got, then it's technically possible, yeah.

The Offsets for writing to the ODO are:
00 = ODO
01 = Body/Fuel - and maybe more. The data in here is very cryptic and we've been working for awhile to decode it without much luck.
02 = Police Mode 'Offset' for fine tuning the digital speedo (usually 00)
03 = A bunch of settings. I'll focus on this.
To write by offset remember that it's 3B. So go back to the original post for setting up an ELM to write to the IC.
For offset 03, low series clusters use 1 byte, and high series clusters are 2 bytes.
Byte 1:
Bit0 = Seatbelt Reminder
Bit1 = TCM Jewel
Bit2 = Police Mode
Bit3 = May be the Shift Alert - but not sure yet
Bute 2:
Bit0 = HDC Jewel
Bit1 = DSC Jewel.
So if you have a low series cluster, when you read offset 03 you type '2103' and you should see something like:
727 03 61 03 03
It''s the last byte we're interested in here.
A high series cluster with DSC on and TC off may look like:
727 04 61 03 01 0E
It's the last 2 bytes we're interested in.
03 HEX = 11 Binary (Or 00000011).
01 HEX = 1 Binary (0000001), 0E HEX = 1110 Binary (00001110)
(Note: I don't yet know what the bits 2 and 3 do yet in the high series Byte. )
Bit 0 is LSB - or Least Significant Bit - and is the rightmost bit. To enable Police Mode you need bit 2 set to 1, so thats 00000111, or 07 Hex. So you write this as:
3B0307 for low or
3B03050E for high
Hope this helps.

Hi mate sorry to bother you but i am having a hard time getting head around this i have a BA falcon RTV ute and have managed to get police mode on with TC jewel on also can turn police mode off but for life of me cant get TC jewel to turn off either have a high series cluster trying to figure command to turn both TC jewel off and police mode, |

eg. read your settings.
2103
returns:
727 03 61 03 03
Take the 2nd last byte, here 03. decode it into
0 (1) - seatbelt reminder
1 (2) - TC
(everything else is off)
2 (4) - Police Mode
If all you want is the seatbelt reminder left on.
Write back 01:
3B030103
Seatbelt + Police would be 05. Everything off 00. etc.
(the above is for a high series cluster. |

Might be easiest if you type the following into an ELM via Hypterterm while connected to your car with the ignition on, give us the response, tell us what you want to do, and we can tell you what command to enter. We're assuming you've got a good connection to the elm (correct com port and speed settings).
atsp6
atsh720
2103
...and then tell us the output from the 2103 query.

Smack bang in the middle of the previous post is a reference to Windows Hyperterm - it's in programs - Accessories - Communications on most machines. If it's not there it hasn't been installed, so you need to go to the control panel and Add/Remove programs, Add/Remove Windows Components.
We also discussed Hyperterm quite a few pages back.
Any Serial based Terminal Emulator software will do.

Ig you want something a little more user friendly (but don't generally allow these kinds of 'mods' to be made) have a look at PCMSCAN or ProScan.
I still use hyperterminal for the reading and writing to the cluster (as the above tools don't let you change away from the PCM). |

Wow !! Great stuff .
For what its worth Jaycar have an OBD 11 scan tool listed in their cataloge along with a special note that they are tired of being a free hire centre & know its a good product so no long accept returns under their satisfaction guarantee.
So I think maybe its worth checking out one of their many shop soiled returns .
Cheers

auMatt and I are working separately on software that will work with the ELM and is specific to the BA/BF/SX/SY.
You'll struggle to find any software on the market that can do much more with an ELM than just the standard J1979 stuff. Even the Jaycar tool can only do that.
Tools with proprietary BA Ford capability are always $2000 or more. The closest you'll get is ScanXL - which is made my PalmerPerformance and is the evolution of PCMSCAN - but this only has Ford Specific codes from the PCM, and you have to buy the Ford specfic stuff on top of the base ScanXL software.

Yeah I have so far written 2 programs, B Series Cluster Tool which is an ELM compatible Instrument Cluster tool that allows you to setup all the options via the can bus, also has functions to check speedo/tacho calibration etc.
My other program is the B Series Cluster EEPROM Tool, which allows you to edit a Cluster EEPROM file (which you would need to get from the on board EEPROM). This allows you to do alot more as in set different speedo ranges, change cluster to a High series and also change the odometer etc.
Both of these are in final testing stages now.
I am looking at developing at least another 2 or 3 programs, B Series PCM Tool and BEM Tool and a B Series DTC Tool. The DTC tool will be released on here when its complete.

Thats awesome Matt, i said to luke ages ago if he could develop such a thing id be happy to contribut emoney towards it, as i am no where near as geeky as you guy sat reading binary and playing with hyper term |

Mi Moit came to work today with his MIL light on. BF XR6T. Freaked him out a bit.
So we plugged in and pulled out the DTC's from all his modules. Thought I'd share them with yooz. I've pulled out the DTC's and converted them. What i haven't shown is the command to change the Header between modules, and to change to ISO and set the values for the RCM.

He does have a dying battery, which would account for some of the low-volatge and CAN comms errors. The VSS is the big one - not sure if that's because of a low voltage or not. Some can be ignored - like internal temp sense and seat memory since he doesn't have them.
But the pedal Box errors and the BEM horn/wiper errors scare me a bit. Hopefully they are low-voltage triggered issues, otherwise they point to potential loom problems.
He's going to change the battery today, we'll reset the DTC's, and see how many come back over the weekend.

Yeah, scares me a low battery can throw so many errors. VSS sounds problematic though, it's gotten from the ABS system, so I guess low voltage to it would cause ongoing issues with VSS too.
Glad you brought this thread back up....
Way back when, when I turned on the police modem all was good. it agreed with my GPS, and the speedo needle showed a few km/h more (3 to be exact).
Sunday I ran the battery somewhat flat, and while trying to turn it over (before I realised it was flat), I noticed it flash 'POLICE' in the odometer area (never seen that before), and now the needle, police mode readout, and GPS all match - weird.
Now what do you want me to check, to see what's possibly changed, why would the needle with it's factory implemented 'error' safety margin, now all of a sudden be correct.
I'll have to double check as I got new front tyres today, see if that's had any effect. |

any ideas if possible to disable ABS all together?
I'm thinking in a retrofit situation which would stop the ecu / other things complaining about the abs system missing
also whats the best deal on the module and getting setup to fool around with ba can network?? |

Not that I'm aware of with the tools I have. Maybe the custom flash software that's used with the SCT (CAPA/Herrod/BPT) Tools might be able to do it. I know they can disable Smartshield.
And all through this thread we talk about the ELM327. Go look it up on eBay. You should be able to get a 1.2a USB version for $50 incl shipping from China.

Yes, I was aware of that as well. But curiously, the ABS module doesn't come up with any DTC's at all. It did strike me as odd that all those other modules would throw up DTC's on no VSS when the ABS Module hasn't noticed a thing.
There's something else going on here. He does complain that every now and then his car starts and the speedo just doesn't work at all. On shut down and another restart it works fine. Various attempts to find the issue at his local service centre have turned up empty.
He's going to let me have the car over the weekend to do some more diagnostics. Aside from dumping the guts of all his modules, I'm interested in seeing if I can pull out the snapshot data that triggered his MIL, and do some full On Demand diagnstics, especially on that ABS.
