Dash ECU location?
Discussion
Apologies for what's a fairly simple question, but the search is down, and it's now dark outside!
Anyone know where the Dash display ECU is located on a mk2? (Presuming that they have a separate ecu?)
Since collecting the car from the rebuild, the display has been intermittently displaying odd characters out of place etc. It's slow got worse and now the rev counter is going crazy, which is setting off the red warning led/beep as if it's over-revving. I've taken the pod off and cleaned all the connectors and it hasn't changed so can only presume it's the feed.
From a quick look... it's a proper jungle of wires so thought someone might have already had the same issue and located the little b
d already?

Mine does a similar thing, you'll be tootling along and then all of a sudden the dash screen goes completely blank and does not return until engine is switched off and restarted. It can be fine on occasions, drove 150 miles to Norfolk on Friday no problems, but coming back, went blank within about 5 mins.
Occasionally it displays random characters on the screen, but it has never affected the drivability of the car, you just simply cannot tell what the oil temp is or fuel quantity. there is the speedometer needle which tells me how fast/slow I am going.
At first it scared the hell out of me, 70mph on the M1, but I have got used to it now, and put it down to the car's personality.
Hope you get yours sorted

Thanks guys. Located the ecu, and having taken the pod off and reconnected everything, I now have what appears to be a stable screen with no random characters, but still have the rev counter reading incorrectly.
As the engine is running fine, i'm working on it being a loose connection or the ECU being odd.
Graham.... I couldn't find an fuses in the passenger side? Only door ecu, a heater thing (2 capacitors and a connecting block), and then the normal heater pipes etc. What does the 80a fuse connect to?
Cheers

Mr Chips,
Having only owned my Mk1 Tuscan for 4 weeks, I am not exactly a font of knowledge!
But, assuming that all the other "spurious" display characteristics have cleared by reconnecting all the pod issues, yet the speed still playing haywire then does this point to the road speed sensor? Think I read something along these lines on Mytuscan website.
Edit
Sorry, just read rev counter. Does the Speed Six have a crank angle sensor triggering the ECU to determine the revs?

Jimmy,
The Tuscan Mk.1 does not have a stand-alone dash ECU.
The dash is managed by the pcb stack inside the cowling. You are correct in saying that the engine ECU, the mirror ECU and alarm/immobiliser control 'boxes' are in the driver's footwell, The Meta microwave unit is located under the transmission tunnel trim.

Hello Nick
thanks for that confirmation. Just surfaced from another yet useless dive in the drivers footwell.
I guess you do not have the layouts of these pcbs?
My problem is that the sidelights are not working.
Many many thanks anyway!

Bugger!
Relay for the side lights changed on the pcb, it works, one can hear it clicking when I turn the switch but no lights.
Fuses checked of course!
Fuming!
Also worth checking the sidelamp relay 3 on the fuse box if you haven't already done so, should hear it click when side lights are selected, if suspect swap it with the low beam relay 52, you may get lucky!

Sir - I owe you a drink!
The bloody thing wasn't even there. I guess I must have removed it by accident.
Stupid me was occupied with that silly fault for almost half a year.
Cheers mate!!!
That would explain it and glad you got it finally sorted, regarding the beer 'Fur mich einen doppelten' Sir - I owe you a drink!
