JC Posted July 10, 2012 Share Posted July 10, 2012 Someone just needs to look at a wiring diagram for the late clocks to find out if there's an ECT sensor feed to it. please feel free to do so, i can't find a wiring diagram for the late escort :-( Link to comment Share on other sites More sharing options...

The Self Diagnostics Mode gives you in-depth information about your engine and the actual numbers in digital. To use it, follow the steps: * Insert Key but do not turn it on* Press and hold the Trip Meter Reset Button* While holding the reset button, start your car and continue holding the button* Within 10 seconds, the display should change to "test" in LCD font and the needles will do a full sweeping. Release the Button Pressing the button will now cycle through some 17 different modes * 1.Shows a Gauge Sweep* 2. Shows all 8's on the LCD (LCD TEST)* 3. Illuminates all the bulbs on the dash* 4. Displays hexadecimal value for ROM level* 5. Displays the hexadecimal value for EE level* 6. Shows DTC (Diagnostic Trouble Code)* 7. Digital Speedometer - mph* 8. Digital Speedometer - kph* 9. N/A* 10. Digital tachometer* 11.Fuel volume* 12. Engine coolant temperature* 13. Battery voltage* 14. ABS fail* 15. Electronic brake distribution (EBD) failure* 16. Illumination* 17. Crank Sense Helped me diagnose my odd fuel gauge stuff because it gives you true readings. Still think changing the sender to an older one is the best idea.

mojoman Posted July 10, 2012 Author Share Posted July 10, 2012 I've not been able to confirm this, but I think the problem is that the digidials get their feed via the DOL link using the ECU temp sender, whereas on the early Mondeo ECU they got it from a separate sender. that so lost me! Any suggestions in simple JC terms on how to solve the problem?was only messing with the last post id just love to solve the problem Link to comment Share on other sites More sharing options...

More annoyingly for me, none of the diagrams match my own car 100%. I can tell you that cars with factory digidials don't have a gauge sensor fitted - the lower port on the thermostat housing is blanked off. They only have an ECT sensor. Just found this on fordmods: Data Output Link(DOL) The data output link provides serial data for use by the Instrument Cluster, Trip Computer, Automatic climate control, and V8 TCM. The information provided includes fuel flow rate, engine coolant temperature, A/C thermistor (evaporator) air temperature, vehicle speed, A/C state and transmission range position.

Stu Posted July 11, 2012 Share Posted July 11, 2012 Sounds like someone needs to make a DOL emulator Link to comment Share on other sites More sharing options...
mojoman Posted July 11, 2012 Author Share Posted July 11, 2012 Sounds like someone needs to make a DOL emulator My man in the garage is also on the case and is listing on his data as the car of that year has I think a 104 pin ecu but defo 60, iv took out the banking screw under the thermostat housing and replaced it with a single temperature sender.so to wire a temperary guage until the problem can be solved Link to comment Share on other sites More sharing options...
Stu Posted July 11, 2012 Share Posted July 11, 2012 (edited) IIRC there was also a transition period where EEC-V ECU's were fudged into 60-pin EEC-IV cases. I can't remember how long this period was or what MY were affected. Hazy brain these days. Bottom line is, if the digital dials require ECT value via DOL then the only way you'll get it to work would be to supplement a DOL stream. Probably a bit of a PITA. You may be able to take the cluster apart and swap out the actual gauge for an earlier one and run a wire to a gauge sensor. Might be easier. Chances are the gauge itself in the cluster is the same as the earlier ones, but there is a driver circuit infront of it converting the DOL data to an analogue output for the gauge. You might be able to splice in between this circuit and the gauge. Gauge is probably just 3 pins, power, gnd and signal.

The early DOL stream is 12 words - the later one is 16, so my guess would be that temperature is one of the extra 4. From what I've been able to find out, the stream consists of identifier - value - identifier - value , and so on. What you would need to do (as Stu says) is read the 12 word stream and create a new 16 word stream with the missing temperature value. Link to comment Share on other sites More sharing options...
Naylor2006 Posted July 11, 2012 Share Posted July 11, 2012 Some great info lads, so how come the older converted to digi dials escorts have a somewhat working temp gauge? Link to comment Share on other sites More sharing options...
Hezz Posted July 11, 2012 Share Posted July 11, 2012 Some great info lads, so how come the older converted to digi dials escorts have a somewhat working temp gauge?cos the "digi dials" bit is being supplied by the older technology wiring Link to comment Share on other sites More sharing options...

Stu Posted July 11, 2012 Share Posted July 11, 2012 I don't really see the point in swapping in an instrument cluster that isn't really compatible. You most likely end up with an odometer showing the incorrect mileage (which is probably a criminal offence) and a fuel and temperature gauge that don't work properly. All for slightly different looking dials? Link to comment Share on other sites More sharing options...

All for slightly different looking dials? My odometer is only 500miles out....by chance. Far from slightly, also they are far smoother, the speedo is accurate to withing 5mph where as before it was 12mph out at least, it wasnt something i'd thought about really until I went from a Finesse to my new escort which came with the older dials, I noticed how much worse they were, if id never had digi before its doubtful i'd even bothered with the conversion, the cosmetic appeal is great and the temp gauge works well enough for me, it will still tell you if you are running hot or cold. Once i drop my new fiesta fuel pump in also I should have a sorted fuel gauge. I will stress though, having never seen digi dials (I had them for 3-4 years) I wouldnt have been bothered with the conversion.

I honestly think ive got myself in a mix now. That kind of ties in with what I was saying. People are using are a mixture of ECUs and digidials from different stages of product development by Ford. There are combinations that work, and combinations that don't. What you need is someone with working digidials on a 2L conversion to tell you the FINIS code from the label on the dials, and compare it to yours.
