Jaguar S-Type 1999-2002 Factory Service Repair Manual pdf

 

Any thoughts????
this message is from jag owner who began this thread.
My Jaguar is in Los Angeles official Jaguar Dealer service center
Service tech Attempting to clear a P1586 code. .. told this to service manager......

Service tech told service manager ..
"no progress on download.
No coms (communication) with ECU"
"Think it (2001 S-type v6) may have a frozen task bar"

Any ideas or thoughts?
they are stymied.

 

I had this once on my car turned out that the battery did not have the correct voltage and was unable to power everything correctly. Check the voltage it should be 12.6 volts

 

hello LAjag

I have a digital workshop manual on my computer for the s type from 2002.5 to 2008...I downloaded it from this forum...I run windows 7...I live about 175 miles north of you in the central valley...I will gladly load it onto a thumb drive and mail it to you if you like if you still need it...i know you are working on a 2001 but this manual might help if you cannot load it yourself from the forum link....let me know...I could mail as soon as tomorrow

 

Same one as already on here and JagRepair.com - Jaguar Repair Information Resource probably.

 

Here is a link to the Workshop Manual for the pre-facelift cars:

yes I am sure it is because I downloaded it from the forum....so much good info and nice people here...I always look forward to learning from all of you

 

Thanks to all of you....
just now getting back to this forum page...
Thanks for the S-type Service Manual links.

frustrating issue...
frustrating as well.. because also, seems we have to "educate" the Official Jaguar service techs.
Your answers were same as mine.. so I texted service manager..
"sounds like tech let battery get too low during the download. Because download will effect several modules, if current drops before finishing, some modules will be reprogrammed and others not...causing a variety of unknowns. Charger needs to be set at 13 -13.6 volts."

 

Guess what ??
after a week at SM Jaguar Dealer.. a text arrived yesterday ..
"finished reprogramming OK to pick up car"
When I called back... seems car is same.. in Limp mode
They didn't deal with the P1586 and no communication between ECM/PCM and throttle body.

 

Thanks NBcat .. Super!!
actual workbook ... 5056 pages

 

Your dealership sounds incompetent on these older Jaguars. Not at all unusual - so is my local dealership....

Find a good local indie shop who knows the older cars. You will be much better off (and so will your bank account)….

 

I agree with Jon.

Take it to NB Cat. He can't be far from LA if that's where you are.

 

What would cause PCM to not recognize throttle body?
I swapped throttle body for another, and still have same P1586 DTC fault code.
Did continuity check on all wires between false bulkhead connector and TB connector. all seems fine.

week #2 at Jaguar Dealer service center in Los Angeles..
no progress...
Jaguar forum members are by far better suited than Official Jaguar Service center for discovery of answer to this puzzle.
Thanks again for your ideas.

 

Is 2004 a typo? Per your signature, you've got a 2001. Even if a 2004 throttle body will bolt up to a 2001 engine, I believe there were some significant electronic changes.

If the part is correct for your car, I wonder if it is defective. For all we know, the donor car may have been getting the same P1586 code before ending up in the wrecking yard.

As mentioned in a previous post, my '02 V6 had been occasionally throwing a similar P1584 code. I forget the exact details, but I'd suspect the fault is close to your code. A guaranteed used throttle body ($75) from eBay put the fault to rest, never to return. If you can find a similar deal, that might be worth a shot in case the donor part was bad.

 

How about this one? Did you ever gamble on a new battery, as JagV8 has suggested? These cars are very sensitive to battery condition, even if the starter cranks over at normal speed.

Also note the clever way I left blame pre-assigned in case it doesn't help...

 

Playing Sherlock Holmes here. Did you ever resolve this? You said you found a wire with no continuity. That's huge!

Per section 3.1 of the wiring diagrams, that wire is a straight shot from the TACM to the PCM. Assuming it's buried inside a big harness, and the fault is confirmed, you could splice in a new wire at each end and run it on the outside. That would be way easier than tearing the entire harness apart in search of one bad spot.

 

Last but not least, did you try swapping this relay? This had been previously xuggested, but no mention if you actually tried it. Find a non-essential circuit with the same relay. Make sure that circuit works properly to confirm the donor relay is good.

 

Response question by kr98664

Among first things done...
swap relays
check fuses
disconnect battery... perform hard reset
continuity check wiring --between throttle body to PCM plug at false bulkhead (rt)
swap throttle body for used TB from similar car witb same eng size
Still in "limp mode"
As last resort .. sent car to dealer to reprogram PCM...

 

No... you misunderstood.
found odd reading on continuity ck white white wire. ... (note: probably issue with my test)
TO be certain of continuity... as you can read previously...
I created a new connection to bypass that wire with a new wire and new wire tested fine
Without any apparent change in engine, nor throttle Body

 

Can you please confirm the model year of the donor car? I had asked previously, but didn't see an answer. In an earlier post, you had said the donor was a 2004, and your car is a 2001.

A quick look here shows different part numbers for the 3.0 depending on the model year (actually by VIN). Scroll down near the bottom of the page:
