Got an NF, 4.0 litre. Just the other day, I jumped in, and noticed the Trip Computer was stuck on 12:27 Fri 8th. No month shown. Figured it may be the heat, been hot in SA, but, when I got out of the car, the t/c was still lit up. Even with the ignition off, doors locked, keys in my pocket. Stays on all night.! Tried the fuses, tapped it lightly, pushed all 3 buttons in a variety of sequences, Nothing happens....still at 12:27 hours.

Any ideas?? :shock:

Car is stock as a rock, 260k, 4WD ride height, cassette player etc etc.

Disconnect the battery for a few hours. That usually resets everything (including the ECU, there's a process involved in getting the ECU to relearn properly. From memory it's something like idle for 2 mins out of gear with A/C off, the 2 mins out of gear with A/C on, 2 mins in gear A/C off 2 mins in gear A/C on. Someone else could probably confirm or deny the accuracy of my memory :) )
If that doesn't work it may be time for a new t/comp.. possibly the display has bleed or something.

Sounds like the display has cooked itself! If it doesn't respond to anything including the buttons. I have seen a dead gauge cluster screen, so its possible. Can't see how else it would still show up without power. Theres a fuse that should kill it, smartlock it may be called.



I have a spare here I can sell you for $20 if you like, grey with black buttons. Just offering.

Pop the dash surround off and unplug it, see what that does. Bit of a weird one!

Hmmm... Anyone confirm this ? Have done a heap of things in the last week. Rebooting the ECU may be a good idea. Changed out the steering rack, the power steering pump, Ignition leads and Coil pack. About 2 weeks ago, got a second hand exhaust which is 2.5", I guess all of this could be cause for a reboot. Does anyone have the exact series of steps to reboot the ECU ?? (NF I6 Auto 1996)

Disconnect the battery for a few minutes. Thats it.

It will sort out its own idle after a few drives, no need for funny procedures.

Make sure you have the stereo code first if the original is still in it.

Or you could do that, but I have noticed that by doing it this way the idle takes a while to settle itself and the trans also seems to take longer to figure out when it wants to shift.

I guess the point of the process I posted before is to get the ECU used to different loads.
But it's up to you, and yes... get the code for the stereo 1st if you need it :) I think you can call 13FORD and give them the VIN number and they'll give you the code. Some Ford dealerships will try to charge you to supply it... if they do, tell them to go f**k themselves.

Edit.. Also the ECU will need about 30-60 mins with the battery disconnected to reset... not just a few minutes.
