hey
where and which manual can I find the pinout specs for the TCP-ECU-TPS on an 05 volvo 8.1 with the EGC ?
I looked through everything I had for an 8.1GI-GF and cant find anything.
my scan tool is still awaiting the arrival of the version 5 update from rinda I hope to use a friends vodia on it later this week.
the symptoms,so I was told, started about 20 hours ago. occasionally the customer would have to cycle the keyswitch several times or the motor would idle only. last weekend all you get is idle only.
all theTCP, TPS and 5V ref signals check out ok as far as I can tell with a multimeter. I cant find any info on checking the IVS and this hull does not have the MIL.
no alarms have been noted.

Re: DonS

There is a wiring diagram suppliment manual for that model, it's Volvo PN 7745609 for the 8.1Gi-GF, It also includes the other gas engines from that model year.
Hope you get to check out with the Vodia, I've used it a lot on the D series diesels, it's a really great tool once you get used to it.

Re: DonS

Iknow with cars when you have a car that don't idle or stalls it may not be the tps. We have a problem with out nuetral safty switched shorting which causes the idle motor to mufunction or if the o2 sensor reads wrong it will give u a fluxating idle

Re: DonS

One other question rodbolt. Is that engine EVC also?

Re: DonS

so far as I can determine its just EGC. it does not stall just wont accelerate.

bosavy
the TCP controls the TPS via the ECU.
somewhere the ECU is not liking what is seeing and wont open the throttle.
DonS
the tech reps they have sent from chesapeake in the past 2 weeks on some other issues are TOTALO IDIOTS.
absolute wastes of air breathing wastoids.
its to the point that by christmas there will not be a volvo dealership on the outer banks.
the dealer I contract for is over them and so am I.
only took me a year to finally last week I got my EPC update that expired in apr of 05.
still cant get any word on the vodia other than using a friends at supierior diesel. great place by the way.
and the supplement is very good, be aware the actual wires on the connector they show for the TPS is transposed.
myself I am about done with volvo.
its gotten to hard to work with them and I have 3 motors that failed due to what I consider volvo problems and volvo is telling my customers whaaaa.
last one is an 8.1 that was replaced at 45 hours, volvo made the guy buy a new 1200 dollar exhaust to comply with their riser drop, 45 hours later it is dead again now volvo says its not their prob;lem.
so now I have a customer with an 8.1 package with 88 hours on the ECU thats looking at the 2nd short block yet he paid 15K last year fore a new motor and volvo chesapeake is saying tough noogies.
I think just before I head to VE in december I will knock on the presidents door and hand him the keys to all the volvo crap we have sold last year.

Re: DonS

You still have your old beachlink email address? If you do, I just went to the shop and picked up a CD that has the wiring manual on it. It's a 3 MB Adobe Acrobat file, if you want it, I'll send it off.

 

[rodbolt]

Re: DonS

sure send it, ill try to fight this thing with or without volvo's assistance.
I appreciate the help. at least you reply faster than Volvo chesapeake .
if you can find it,i cant, the part numbers to the test harness to plug into the tcp and the tps whould help as well.
I spent 3 hours on the partner network yesterday and cannot find anything.

Re: DonS

You've got mail.
What is the serial number of that engine? I'll see what I can find out.

 

[rodbolt]

Re: DonS

dont have the seriel with me here at home, if it quits blowing and raining Ill try to get it tomorrow.
supposed to have had a rep monday and today show up to look at two other motors to make some kind of decision, still they are no shows.

 

[Don S]

Re: DonS

Did you get the emails?

 

[rodbolt]

Re: DonS

got them
I fwd'd them on to where I will be working on this rig. no sense in fighting volvo's logical setup while not on the clock.
but tommorow is looking like a wash
winds at 30-40 MPH and 1-2" of rain.
if it blows like that I will stay home and study them.
thanks
maybe a volvo rep that can do more than make phone calls will actually show up, oneday.

Re: DonS

winds at 30-40 MPH and 1-2" of rain.

We call that summer! 8) As long as it's over 50°

 

[rodbolt]

Re: DonS

then its a heat wave here, temps are in the mid 50's.
boat does not fit in the bay due to the tower and 2nd station.
I rarely work in the rain and am about to give up cold altogether, cold, by my definition now, is anything below about 60 . thats why I am up so early now, not because I wish but my buddy,arthur, made me.

Re: DonS

Are you sure the warning horn works? It should beep when you first trun the key on. If not, that may be why you don't hear an alarm, Here is a possible cause for the idle only problem, but one would expect the warning horn to come on with no/low oil pressure. Of course, there may be a problem in the ECM or wiring causing it which could bypass the warning horn.
At least it's something you could check.

Forced Idle (ETC engines only): Limits RPM to approximately idle RPM. Currently the only
fault code that activates this function is the loss of oil pressure (below 5 PSI). Forced Idle
status can not be viewed with the scan tool and like Low Rev Limit, Forced Idle is a latched
event even if the active code clears.

Re: DonS

the alarm self tests but I found on an 04 5.7 thats kinda meaningless.
thats one of the other motors this dealership ,me and volvo are doing circles on.
I will have to wait for my friend with his vodia or get my ver 5 chip and EGC adapter for my techmate
I would have bought the vodia 2 weeks ago when I had to trouble shoot a failed ECM on a 4 day old 8.1 OSI but the dealership owner is saying if volvo doesnt help the guy with the smoked 5.7 or the smoked 8.1 with 54 hours on it he is giving up the franchise.
kinda makes it hard for me to eat a 1200 tool that cant be used on anything else.
but I think I may buy the latest diacom software when I get my new laptop.
my old one would puke if I tried to load that software .
I am sitting here with deposits on 3 repowers from volvo and the owner of the dealership wont do anything until the blown 8.1 and 5.7 issues are resolved.
one day maybe a real tech rep with some kind of authority will show up.
I will wait seated though.

Re: DonS

I have a feeling you are going to be SOL for diagnotics on this engine until you can read some codes and data.
There is a new EGC diagnostic codes document (preliminary) on the parter network. You might want to look at, it's in the Service and Warranty section called EGC Diagnostics, size is 5018.

It's a shame about your rep, we've never ran into any problems where Volvo just said, too bad. I suppose If we did, we would probably tell them where to go also. You sure can't sell a product to a customer and have the drop the support and expect to stay in buisness.

Re: DonS

i understand what it does. I Know working on car's and boats are differant. But the tcp got's it;s signal from ecu right. everything now is fly by wire i know boats are a little behind.Does the tcp just work off a ground signal from the ecu or does it also give power to there. i am assuming this is a fly by wire sytem but i not fimular with boating .Were getting the storm you gus had tommorow. well i have a merc with a carb hope fully my issues are simple. good luck

 

[rodbolt]

Re: DonS

the TCP to ECU to TPS works on a dual fault feed back system.
both feed backs have to null each other or the system defaults to idle, however if it defaualts I should get a soft warning at a minimum.
no warnings heard but the audible willl self test when the ign is powered up.
I dont mean to be busting Volvo's chops but I have had 4 failures that I consider a volvo issue and cant get a resolution. all I want is a yes we will cover it or **** on ya.
so far one has been on the rack 7 weeks and the other 4 weeks.
all I need is, is you is or is you aint.
so far 3 different volvo reps have looked at them. they look, take pics and say I gotta make a call my boss man.
I want someone to look at them that can make a command decision.
at the risk of being PC incorrect, I want a tech rep with balls.
dont matter pay wise to me its just I will fight for the consumer if I think its a factory issue.
the owner of the dealership feels the same as me.


bosavy.
go one back to skeeewl
but rur gitten thyeir

Re: DonS

I agree 100% with what you are saying..............
Have you joined the forum yet on the partner network? Who knowns what that could bring. but it sure will be noticed, and I don't mean just the mechanical problem.

Re: DonS

Hey Don. I just noticed that you are from Ketchikan. I'll be coming up there for a week in late July, to a fishing lodge. I sure hope your forcast for summer weather doesn't come true.

I'll have to stop by and say hello.
