So I went to a shop today to pull my codes and this is what I received for my 03 STR:
ABS -
C2778 - Sensor power supply failure
Engine -
P0057 - Heated O2 B2S2
P0327 - Knock sensor / Circuit Low Input
P1646 - Heated O2 B1 open/short
P1647 - Heated O2 B2 open/short
P0480 - Cooling Fan 1 Control Circuit
P1632 - Generator charge system failure / generator load feedback failure
P1260 - Security Input
P1410 - Airclear inlet control circuit
P1582 - Flight recorder Data isstared
Transmission -
P0829 - Geat Load 5-6
P0730 - Incorrect Gear Ration
Body Control Module -
U1041 - SCP vehicle speed signal - invalid missing not obtain
Electronic Parking Break
C1785 - Electronic Parking Break motor output open circuit
U2521 - Missing message from ABS
B1318 - Battery Voltage low
U1900 Can Communications Bus Fault

After all this...when the car was on the lift...I saw that there was a leak behind the engine...calipers were missing on the rear brakes...and a rear strut was bad. There is also a lead in my A/c, sunroof isn't working correctly, and a fuse keeps getting fried on one of the low beam drivers side headlights. With all this...is it worth fixing?? Or should this just be used as my parts car for my other working 03 STR? LOL

 

Check the battery and charging system. The car does not like low voltage and will throw all sorts of bad codes. Also were the definition of the codes from his OBD reader or from a Jaguar chart?

How did you drive it with no calipers on the rear?

+1 on the bad battery.

 

+2 on battery and why would you even purchase a car like this with a multitude of issues, STR or not..

Can't stop laughing about the missing calipers...That's a first...

 

So just for starters you know you have to replace battery, rear calipers & pads, probably 2 rear shocks, probably pull the front bumper and track down at least one electrical short in your headlights, fix an A/C leak, fix an engine leak, and pull the fuse to disable the sunroof if you can get it properly seated and sealed.

How much money do you have?

Go Navy! Thank you for your service. Steve

 

Maybe a different suggestion?

It's real handy to have two of the same car sitting side by side ( I see you have a good STR too). I had two older SHO's of the same year and when it comes to troubleshooting or figuring out how to put something back together, having the real thing to look at and swap parts with is far better than just the factory manual.

You do have the JTIS? You might be surprised how easy it is to find parts on EBay for the STR. Seems to be several being parted out now.

But I think you would need to like to do this sort of work. There won't be any money made by reselling it.

This was his meter, it was a Midas Service Station. Also, I had purchased a bland new battery and these are the same codes as I pulled from an AutoZone Autoparts.

 

There are some other non stock calipers. From underneath you can see the holes where it used to be...emergency brake cable is just hanging there on both sides.

 

You should always use the code definitions that are published by Jaguar for the Jaguar you have to be sure you do not get an improper definition and you end up replacing the wrong parts.

As for the codes now that you have them documented clear them and see what comes back and start from there. Also you have a new battery what is the voltage? Anything below 12.2 is a problem. New battery can have low voltage and that will throw erroneous codes.
