Hello Everyone,

My name is Chanel and I’m new to the forum. Hoping you all could be so kind in helping me find some answers on here. I was driving my sweet ride when it randomly started to malfunction. I turned the car off and it now won’t turn back on! I had to tow it back home. My 2009 Jaguar XKR portfolio series is not starting at all. It's giving the following errors on the dash: "DSC Not Available", "CATS System Fault", "Park Brake Fault". When I attempt to start it the screen and lights come on with all the messages but the car just won’t start. I tried the push before brake method, checked the battery, charged the batter just to make sure which were all unsuccessful in resolving the issue. I plugged in a reader and it just shows everything as a fault. Any help and guide in the right direction is greatly appreciated! I absolutely love my car.

 

It has something to do with the electrical system.
You say you charged the battery, but you said nothing about checking if it was still a good battery. I'll wager it's beyond its usable life. Yank that battery out and bring it to an auto parts store and ask if they would check it for you. Nearly every store will do this for free.
You'll probably walk out with a new battery because 'dead'. Also, when you get a 'new' battery, CHARGE IT! No New battery comes fully charged. Ever.

 

Welcome to the forus Chanel,

I agree with Cee Jay.

A partially discharged or failing battery is the number one cause of weird electrical/electronic issues. Eliminate that before looking at more obscure and expensive possible causes.

Hi Cee Jay! Thank you so very much for the suggestion. You’re correct, I forgot to mention I did take the battery in and it’s sadly not that. I so wish it was because that’s a quick fix.

 

Then it would probably be either a battery connection problem with the cables or a bad ground point on the chassis. Those are a bit tricky to find as you have to locate and inspect each one. I've no idea where they are, but many people in here do know.

 

Thank youuuu! I’ll definitely look into that. Much appreciated.

 

I still think battery is suspect but what the heck. What was the voltage of the battery at rest when they checked it? I assume they did a load test on it? Have you considered buying one of these? It would give us DTC codes to work with.


I suggest this one because it will read all codes, (body, chassis) not just engine and will help you find an open circuit.

 

Thank You for the guidance! I have taken the car to a trusted mechanic. It's confirmed that the issue I am faced with is not the battery. He put in a brand new charged battery and ruled out that factor along with the connectivity to the battery. His guess is it's the ABS control module behind the right wheel? Says that there might be a form of short and it possibly needs to be fully replaced. He's going to try to do his best to see if its fixable and let me know today. So bizarre how it randomly stopped working, my car is so well taken care of. I appreciate this forum so much, glad I found out about it!

 

I think those issues would still allow starting.

 

Ok well you trust him. I've not heard or read of an ABS module preventing a car from starting though. An ABS system is unique to the braking system and not related to starting the car. Without a list of DTC codes we won't be much help but please keep us apprised. If his conclusion is that a faulty ABS module is the cause of a no start, I recommend you get a second opinion.

 

Hey! Thank you for the reply. My mechanic just called and you’re correct it’s not the ABS. It’s confirmed that it’s not the battery even though I understand everyone is swearing by it on here. He has zero clue what it could be. The DTC code shows C0044-28 ( Electrical- Instruments - warning lamps - Dynamic Stability Control lamp illuminated) Brake pressure sensor A. The car will power on but not start at all.

 

Hey! Unfortunately, those issues aren’t allowing my car to start.

 

Out of curiosity, what is the voltage across the battery terminals with the ignition in the OFF position when checked with a voltmeter?

 

I so wish it was this! We eliminated the factor that it’s unfortunately not the battery (Sad face). Thank you for the suggestion.

 

well there you go - I did learn something new. Thank you. The code gives something to go on. This applies to MY 2007 but may be your issue too. Your Mechanic will need SDD to carry it out. (ABS Calibration)

 

Sounds to me the brake pressure sensor is at fault!?

 

That certainly qualifies under

The only impressive bit is the 0.3 hours under Time allowed. Takes me longer than that to connect up and boot into SDD!

If it's not the battery, then listing the available voltage should not be an issue. This is often the starting point for a full diagnosis. Guesswork on a Jaguar can become very expensive very fast.

What other DTCs, if any, are stored in the system?

What recent work has been carried out on the vehicle?

 

Hi Chanel, I recently purchased an '09 Coupe and had a similar problem. My car would start sometimes. Sometimes it would take two or three pushes on the ignition. Sometimes it would not start. My mechanic thought it was the ABS module but thankfully it was not. They are a JLR certified shop and talked,a lot, with techs at the factory. The Techs were stumped as well. Finally their solution was to replace the starter button and do a software update. Starts every time now. Not sure if this is unique to my car but when I start it I; push the start button, wait for the red flashing light on the center of the dashboard to go out and then I step on the brake and push the starter.

Best O Luck

 

Hi Keating & Everyone,

Just wanted to say I greatly appreciate all your help, suggestions & expertise! Turns out there was a short in the start relay that was causing all the problem & chaos! After the replacement, the car turns on and works great! Couldn't be happier.
