[urq] RE : toasted ECU?

[Louis-Alain Richard]

Brian, 

 

Replacing the ECU is the last step in the VAG official diagnosis of a
no-start condition. To find this procedure, download the PDF of the
"introductory service training" manuals here:

http://www.quattro.ca/Urq/urq-IST-MaintAdj.pdf

Look at page 21 for the procedure.

 

 

You can also download this document, which is the general explanation
of the car:

http://www.quattro.ca/Urq/urq-IST-Introduction.pdf

 

Armed with that, you can easily do a dozen simple test, and conclude
if the ECU is dead or not. 

 

Hope this helps,

 

Louis-Alain

hi fellow fans,

 

i am somberly typing because while testing for a cranking no start

condition, it turned into a no nothing condition.

 

in short, the battery was dead and i was under the hood using my test
light, pulling the coil to dist plug,etc.. to test for spark while a
fellow vw friend was manning the jumper pack in the backseat and
turning the key on my command. ... wellll, its very possible that he
forgot me telling him that the (opposite of typical) power strap is
black and the ground is orange on my 84-Qt..

 

sparing a longer clarification of what i suspect,,  the point..  i
have a

MAC-2 hitachi ending in 383F as i imagine most ur quatts do.  what i
ask is if there are any ecu's (say from a 5ktq) that can be swapped in
for testing purposes &/or  are there any bonafide tests i can carry
out w/my multimeter across certain pins or points within the ECU to
determine wether or not my ECU deserves butter&jelly or if i missed
something while pulling fuses and relays..

 

very frustrated and looking for some insight..
