My 2013 XKR starts and runs for about 20 seconds. Shows no RPMs. Message: Fuel Low. Tank was filled day before. Gear selector fails to elevate.
HELP!!!!

First thing to do nearly EVERY time you encounter a problem.......... Check the battery voltage (HAS to be 12.6 volts after sitting overnight) and do a Hard Reset by touching the disconnected battery cables together for several seconds while avoiding any contact with the battery itself. This resets all the volatile memory in all the modules and may very well cure the problem. It costs zero dollars and takes maybe ten minutes. No sense in doing anything else until this is tried first.

 

HELLO Cee Jay:
Thank you for your response. I did do what you suggested before and no fix. I should have reported that the car started when I backed out of the garage and shut it off. About 10 minutes later, the problem started.

 

So what is the resting battery voltage?

 

11.85

 

problem solved.....

 

To be more specific from Post #2 and Post #6...

 

Just back from a week away . Battery reads 11.2 volts . Not been on maintenance charger.
Car started instantly, all systems functioning perfectly.

Just for a bit of balance and a reality check .

 

What Cee Jay shared is the importance of the first pinpoint test.
On failing this test, it must be corrected before moving on to the next.
50% of all issues dissipate with the correction of pinpoint test 1.
Other observations are irrelevant.

 

Yep, the reality of your battery being way too low.

 

Too low for what?
The vehicle starts immediately and all systems operate fully .
This forum has some members who are battery voltage obsessed, trotting out a cut and paste answer on battery voltage, battery condition ,then usually reverting to description and debate of charging and maintaining devices, culminating in voltage testing device bragging.

The reality is in my garage today, I don't have anything like the 12.6 volts measured after a full night's sleep with the voltage wonder wand device.

The car does not require the mythical number in practice and claims it does may not help resolve all situations.

 

I think most issues on the older, electronics aided Jaguars is corrosion. Had Jag+Ford used gold plated connectors it would have helped stave off those slight increases in resistance which ultimately affect the voltages that the software measures and subsequently interprets as faults, here and there.
A full capacity battery helps avoid these faults.

Err, yeah. A look at the JLR support knowledge base may be enlightening.

Or, have a read of the workshop manual.

Or, purchase a replacement gear selector module. Many others play musical parts until, by luck, the issue is solved.

Perhaps our assistance is of no value to you.

 

Recharged battery overnight = 13.2V...no help.
Attached Hulkman jump starter 8.5 = 12.4V...no help.

 

Firstly, from the workshop manual:"If the JaguarDrive selector does not rise from the console when the engine is started, but electrical power is supplied to the

selector, the retracted selector can still be rotated to make selections. If electrical power to the JaguarDrive selector is lost,

the selector will not rise from the console when the engine is started and the retracted selector will not rotate."


Secondly,

NOTE: The JaguarDrive control system is a co-ordinating system only. It CANNOT generate a fault in one of the participating

sub-systems. All participating sub-systems should be FULLY diagnosed before assuming a fault with JaguarDrive control. The

JaguarDrive selector module should not be replaced until all other options have been exhausted.


Lastly,

The JaguarDrive selector module and the mode buttons should only be investigated if there are no apparent faults in any of

the sub-systems. If a fault in a sub-system is subsequently corrected, the JaguarDrive control system will function normally

after an engine on and off cycle.


If a fault occurs in the JaguarDrive control system, all button icon LED (light emitting diode) will be turned off (if applicable,

background illumination will remain on) and pressing of the JaguarDrive control buttons is ignored. The instrument cluster

message center will display a message WINTER MODE FAULT or DYNAMIC MODE FAULT when the fault occurs, if the fault is

present and the driver attempts to select a special mode (if the control module is able to do this) or at the next ignition on

cycle.

The JaguarDrive control buttons and selector module are an integrated unit. If a fault occurs in either component, the whole

unit will require replacement, however, this is extremely unlikely.


In summary, assuming the electrical source is good, what codes have been thrown?

 

A low battery at start can give weird problems. Not all the time, and they vary from low battery start to the next low batt start. One time my power steering wasn't power steering anymore. Another time the centre display was weird. I'm lucky to have a Jag that has a very low current drain when turned off (around 6 milliamp) when I bought the car.

The problem with letting the battery drop low is sulfation and degradation over time. If your car has a high milliamp draw when shut down a battery tender is the way to go.

 

This thread is dead to me.
