I hope someone can help me. I have a 2004 XJR w/supercharged 4.2L and it won't crank or start. Yesterday it was running fine, then I took it home and washed it. This morning it would not crank or start. The interior lights blink and it makes a buzzing sound each time I turn the key. I can release the parking brake and can hear it engage. I located the OBD connector and retrieved 3 codes (P1111, P1338, P1000). Additionally there is a message that says " No DSC available, and No Cruise available". I cleared the codes and still nothing. I disconnected the battery for about an hour,. reconnected and still nothing. Other things I noticed were the radio would stop playing if I turned the high beam lights on at the same time, and the J shifter can be shifted out of park even though the engine is not running. (Is that normal?). I took the battery out and it is now charging, in case that's the issue.


Is it possible that the ABS sensors got damaged during the wash? ( I did spray under the car). Please help....

 

the ABS sensors are water proof .
what was the voltage in your battery ? it sounds like it was low on power .

 

It read 12V, but I'm not sure about current. I have it of the charger right now and will try it in the morning

 

The only likely thing that changed with your car from when it was working to now non working is that something got wet that should not have.

My guess is that water got into an electrical connector somewhere and is causing the issue.

Do you have the under body shields in place on your car?

If you sprayed under the car and water splashed in force up into the engine compartment is where I am going here.

 

I think you're right. I let it sit all night and all day, plus I charged the battery last night. It's starting now, so I really don't if it the water or the battery. But, I will keep an eye out in the future. Thanks for the input..

May still have the $10 rebate as well. 9 year warranty, 40 month free replacement and free jump. $109. Best deal on the correct calcium type battery there is.

Also, you need to check the two bolts on the side of the transmission where the shift cable is attached. It is a known issue that they can back out causing a no-start condition.

 

If you let the car stand for days at a time between drives a CTEK battery minder might be worth the investment as well.

 

Thanks, I'll look into it. Do you know a good source for it?

 

I cannot recommend strongly enough to replace the battery with the one I posted above. There are more issues due to battery failures due to age or incorrect replacement than just about any other issue with the XJ8. I also highly recommend that you do not use AGM in your vehicle, the ECM charge rates are too high for allowed charging voltage for AGM (max 14.4) as Jaguar uses a 14.6~14.8 float voltage. Jaguar specifies Silver-Calcium batteries, and standard antimony batteries are not the correct type. Since Johnson Controls (who makes the overwhelming number of auto batteries, including Interstate which was at the time recommended by Jaguar) has stopped making any calcium batteries a few years ago, Exide is really the only one making a calcium battery designed for this application.

The correct CTEK charger for calcium batteries is;

Thanks Box,
I'll check both of them out. There is a Home Depot less than a mile from my home.


Thanks...

 

Got a new battery from Home Depot on Sunday (problem solved). Thanks guys. I'm now waiting on the CTEK battery minder from Amazon. Now that the low battery problem is solved, I would like to know if anyone has ever pressed the upper ball joint out and if so what ball joint (manufacturer, part # etc,,) did you replace it with. Thanks in advance..

 

Front upper ball joint is replaced with the arms alone. You can save a bit by searching this thread and finding the arms used for S-Type.

 

Thanks Box. I was afraid of that. So, you're telling me that the S-type are the same as the XJR?

 

As I understand it, only difference is price. Lemforder is the one who originally made the arms for Jaguar, and the Ford Thunderbird/Lincoln LS and Jaguar's S-Type also used the same arm, under a different part number. I cannot attest to the composition of the bushing, but reports are that they are the same. I would do a little research through the threads first, as I have not had them in front of me.

 

Thanks, That's good to know. Saving money is always a good thing. I'll do a little research to see what I can find out. I'm sure there are other parts that interchange as well..

 

Hi joeleerj,

Search eBay for "Jaguar S Type Control Arm" for some very low prices on the front upper control arms/ball joints. Searching "Lincoln LS Control Arm" will produce many of the same results. My assumption is that these low-cost control arms are manufactured in Asia. I don't know if we have enough data to know if they will last as long as the European-made OE Lemförder units.

You can also search Rock Auto for the control arms for 2004 Jaguar XJ8, S-Type and Lincoln LS to compare options and prices. They carry the OE Lemförder part numbers 3063101 and 3063102, as well as several less expensive options.


Cheers,

Don

 

Thanks Don,
I'll certainly use this info..

 

Lemforder from RockAuto is my suggestion as well.

 

Can you please elaborate on this?

The charging voltage of battery charger is determined by the power supply (i.e. the charger), not the receiving circuit.
The modern Ctek chargers are running a charging cycle with different voltages and currents and they are claimed to be compatible with AGM batteries.
If 14.4V is the maximum for AGMs, then the cycle probably does not impose voltages higher than that.

Would you mean that the Jaguar electrics/electronics require a higher voltage to operate satisfactorily, so that the voltage delivered by the alternator during engine operation (float voltage) would be above the threshold tolerated by an AGM battery?

 

AGM technologies do pose some unique charging problems. A battery's ability to take a charge is determined by a battery's resistance. A charger's ability to provide current, not voltage, is determined by size of the power supply. That's why 10 amp battery chargers weigh 5lbs, and 125 amp chargers weight is 50+. Smart chargers like CTEK senses resistive load, and not all CTEK chargers are for AGM. Our vehicles though, are not designed for AGM. What happens when you provide too much voltage, the battery overheats. The individual cells in an AGM are sealed and are sensitive to overvoltage, in fact on many, it will tell you on the label on the battery itself that charging voltage should be 14.2 +-.2v. The upper range of the pulse width modulation provided by the ECM can be levels up to and over 15 volt, (and that's okay for very short periods of time) but will under load provide around 14.6~14.8 volt duty cycle which it too high for AGM and antimony (conventional) based batteries. Silver Calcium batteries require a slightly higher voltage to charge, as the calcium is a reactor inside the battery's chemistry, which is why when Jaguar adopted Silver Calcium (for long life) they raised the charging voltages in the ECM duty cycle. Most vehicle electronics easily survive and operate in a range of 12 to 16v. For Jaguar, any programming done to electronics should include an external power source (charger) during operations, and is specified numerous times and places in Technical Training Guides.
