Hey guys i have a 2001 Jaguar S-Type V6 3.0. i took out the dash and fixed the evaporator then i placed everything back together. when i connected my battery not only was it dead but when i jumped it the car it would not start. It gave me a LOW fuel level (which is not true) and than the alarm system seems to be going off when i try to turn it on. all the car does is crank and doesnt start (then the alarm goes off). please help out thank you in advance.
oh the car also gave me a Fuel Computer Data Error.

 

Chances are a cable came loose / got cut or the like. If it shorted out the battery you're lucky it didn't cause a fire!

If I had to guess, I'd say a cable going to the dash (cluster). Dealer-type OBD tool (such as AutoEnginuity) can talk to all the modules and report any that aren't found, which would really help figure this out. However, sounds like you may now have car in anti-theft and I think real jag tool may be needed to get it out. Worth figuring out the cable/connector issue and checking before calling dealer.

 

Thanks for the quick reply I guess I'll try and check cables and connect my OB reader. Question once it's in anti theft mode what can I do to get it off?

 

Dealer tool.

An ordinary OBD tool is next to useless to diagnose the networks as it will only talk to one out of 10-20 modules.

Figure out fault and pray it's not in anti-theft.

 

Well just bought a new batt. And I just remembered does it matter if the radio is connected. Mine wasn't on when I tryed starting it.

 

well just connected the radio and put in my new battery checked the cables and all seems connected and well. still no start it cranks but doesnt start. the red light is flashing and my windows dont even go up! im confused as to why the window dont go up. seems like all else works well in the car. i have no idea what to do or even where to start.

 

What red light?

Check everything else on the car to see what might not be working correctly. That may help narrowing down what went wrong. I'd guess you missed reconnecting a harness or something while doing the evap repair. Pay particular attention to the area around the steering column and going down into the console.

Good luck!

 

Check the inertia switch in the foot well, drivers side - make sure the button is engaged. Just an idea....

 

XJr i will be rechecking all of the harness and make sure its all connected well and reply back with anything new.

my inertia switch is done i checked it yesterday.

does anyone know someone that knows jaguars that lives in FL.? dont want to take it to the dealer! hate them!

 

Just check the PATS code and got a 16 which in turn is a code for. U2511/U1900 Instrument Cluster to engine control module (ECM) Controller Area Network (CAN)
communication error. does this mean that i must have must some connection or ground when replacing the Dash back in ?

 

I think that's what I kinda said! Maybe just loose cable. You won't know till you look...

 

i hear you jagv8 i have been slowing taking off the dash again looking connector after connector like you said. just want to know if some one can elaborate more on "U2511/U1900 Instrument Cluster to engine control module (ECM) Controller Area Network (CAN)
communication error" or if some one has had this problem how they fixed it IF it wasnt a missed connection.

 

Just for grins, check these fuses:

Primary Box-RH footwell #4 5A
Front Box, Eng Compartment #10 20A and #18 40A

Cheers,

 

well i did a check on all the connectors and everything seems to be good. everything is connected and all grounds seem to be in place. any other idea on what the problem may be? could the ECM have gotten wet and thats the issue? it rained 2 days and my windows were down. but i covered it with towels the first day (last sec thing miami weather is fast and crazy) and the second time i placed plastic bags and some water got in but not to much. i just put everything back together and am waiting to connect the batt. again to see if there was any changes. i will update. please if anyone has any other ideas please let me know.

thank you in advance
PS if i get a new ECM from a junked jag would i be able to connect it and it be compatible?

 

XJRGUY Fuse list:
4 good
10 engine comp. there is not one there ( should i Have one?)
18 looked good.

2001 Jaguar S-type 3.0L v6

 

Ouch! Yes, It could have gotten wet. Always helps to have the rest of the story.......

You can use a PCM from a junk car as long as....

1. the car is identically equipped.
2. the number on the PCM is the same as or a successor to yours.
3. it is NOT programmed as a new module [that makes it junk, too]
4. it has the "Immobilization Setup" application run on the Jaguar IDS/SDD tool. That allows engine starting.
5. you are not in an inspection state. Not programming as new so the VIN# is burned into the PCM will cause you to fail inspection.

Hope that helps!

 

Can I test it to see if it works or is there Any way of knowing if it properly works. And guess I may have to go to a junk yard and test my luck.
