Title: Ignition - Electronic DIS module
Post by kanor on Oct 25^th, 2007, 6:55pm

Hi.

On my Scorpio 95' 2.0 16v I do have a missfiring problem. Wiring loom and coil packs are new, but stil problems. http://www.carsoft.ru/avtorepair/sierra/engcntrl20.pdf indicates that my car is equiped with a "Electronic DIS module" but where is this module located on my car ???

inside the engine compartment.

If you look behind the right hand headlight (drivers side UK) and below the front of the coolant reservoir you can just see it screwed onto the inner wing

When you changed the coil packs, did you change the two HT leads as well ? :)

Just checking ;)

Hi there.

Thanks for reply. ;)
Yes I did change the HT-leads, or more spesific; I reused the connectors, just replaced the wire with a type without resistance but it had no effect on the missfire. ???
I will do some more faultfinding in the coming days now that I know where to find the DIS-module and keep you informed about the progress.

Is your misfire constant or at high or low revs only?

Alistair on the forum had a problem with the loom from the EDIS module, might be worth a check.

I have a spare working EDIS 4 module which fits the 2.0 and the 2.3 if you want to try it and rule that out

Hi Kanor

As Stuart says I recently had the same problem to a much greater degree i.e. tickover for a while then flutter and die. Turned out to be a broken (intermittent) wire between the EDIS and the ECU. Discovered by a diadnostic test as below:-

Pin 1 EDIS to Pin 48 PCM (ECU) - black and white
A four channel scope
Channel 1 EDIS positive - Ignition feed
Channel 2 EDIS ground
Channel 3 PIP signal
Channel 4 Crankshaft Sensor

This is the wire that ensures the constant 12 volt supply to the fuel pump. Could be that yours is heading that way.

Having been through all that It does seem that your problem i electrical and the EDIS unit probably the culprit.

Good luck

Alastair
