Hi, I bought a 2009 XK that had been in an accident, hit a mini roundabout damaging the front bumper headlight, air filter and suspension.

I have had the engine running but now that all the repairs are finished I can't get it to start and I'm getting a raft of error codes.

I'm thinking they could be linked through some electrical issue, possibly due to the car sitting a length of time when I repaired it or more accurately waiting to get second hand headlights at a good price and perhaps connections have got corroded or something but its past my level of knowledge.

Error codes are:

U0122, P0113, P00AD, P0102, P010C, P0113,P00AD, U0121, P0560, P0560, P0615, U0122(87), U0126(00), U0416(68), U0401(08), P0615(13), P057B(87), U0122(87).

Any pointers or suggestions would be greatly appreciated thanks.

Regards

Murray

 

Battery?

 

It's (almost) always a weak/dead battery or a bad ground. With the engine off, if your voltmeter shows less than 12.6V, charge the battery with a 10AMP or greater battery charger (not a battery maintainer or trickle charger).

If that battery is over 5 years old, you should buy a new battery and make sure it's fully charged before you install it.

Good luck

 

Use a voltmeter to read the available voltage across the battery terminals with the ignition in the OFF position for at least thirty minutes. There should be a minimum of 12.6 volts available for all the modules to function correctly and communicate.

If the available voltage indicated on the voltmeter is less than 12.6 volts, charge the battery for five hours at 2 to 5 amps and retest. If the voltmeter still shows less than 12.6 volts, the battery is suspect and should be replaced.

Many random DTCs and instrument cluster warnings are the result of a failing or weak battery.

 

Many thanks for the help.

The battery was the battery that was in the car when I got it, its been disconnected and stored and charged before I put it back into the car but battery was reading less than 12.6 volts after it was charged. It was reading around 12.4 volts. I'll put it on charge again and see if it reads above 12.6 volts and if not I'll buy another one.

 

Thanks for the reply.

I would imagine the battery is over 5 years old, it was reading around 12.4 volts.

I'll put it on charge again and if it reads less than 12.6 volts I'll buy another one and see what the situation is then. Hopefully a lot more promising and a lot less confusing.

 

And those are not complete JLR codes. The complete code will be more telling of the issue at hand.

Cheers!

 

There's a lot of electrical systems in these cars that can lose communication,they operate on a can bus and its not unusual in such systems for this to occur. occasionally a complete restart (also heard it referred to as a hard start) is necessary. It is easily accomplished with a suitable after market scan tool (don't know which ones work fully) or an OEM JLR scan tool, like wise removing the battery for a lengthy period can achieve the same thing. This will reset a number of your systems like electric windows, radio etc and you should read the many threads on here for reprogramming those things. I don't know how long the battery needs to be removed for, on other (non x150) cars ive wiped the memories and cleared stored codes stored by the presence of capacitors by disconnecting positive battery, isolating it from the post, connecting positive to negative with a jumper wire, which drains the memories completely. A reputed Jaguar mechanic said this would work, i haven't tried it but i certainly will if i get an issue with a locked up ECU situation.

I have also recently experienced the multiple fault code problem as a result of incorrect voltage on my battery. I'm in Texas and the battery was 8.5 years old, we typically get 3 years here, so i should count myself lucky. The previous owner kept it on a battery tender, read plenty of threads in here on that subject.

Good luck.

 

Thanks for the advice.

I've had the battery out on charge for a few days and am just waiting for a Jaguar specific code reader to arrive.

I'll do the hard reset with the two terminals and leave it for as long as I can and hopefully that helps clear the issues too.

I'll also put in a new battery

 

No need for the reset if the battery has been disconnected for days. Looking forward to seeing the codes.
Best of luck.

 

I was told by a Jaguar specialist that just attaching a Jaguar compliant code reader or scan tool was sometimes sufficient to reboot the canbus and get the ECU all talking to each other. If your code reader works well and has any special functions on it id be interested.

 

I bought a new battery and icarsoft Jaguar code reader.

The error codes are:

P057B Stored Brake pedal position sensor A circuit Range/Performance
P0560 Pending System Voltage
P0113 Pending Intake Air Temperature Sensor 1 circuit High Bank
P00AD Pending Intake air Temperature Sensor 1 circuit High Bank 2
P0102 Mass or Volume Air Flow Sensor A circuit Sensor low
P010C Pending Mass or Volume Air Flow Circuit Sensor B Low
U0121 Pending Lost communication with anti lock brake system (ABS) Control Module
P057B Pending Brake Pedal Position Sensor A circuit Range/performance
P0615 Pending Starter Relay A circuit
P0113 Permanent Intake Air Temperature Sensor 1 Circuit High Bank 1

The dashboard shows an ABS fault and parking brake fault

 

@Rastasal67 , even though the battery is new, would you please take a voltage reading, ensuring the engine nor a charger has been attached for 4 hours? (I typically say 6).
I'm afraid I cannot rule out an insignificant electrical source, yet. Once we can, we can move on to the next pinpoint test (from the workshop manual)

 

I had put the new battery on charge over night and then put it in the car.

Sorry I didn't realise that you needed to leave it connected for 4-6 hours.

I'll reconnect it tomorrow and leave it for 6 hours and see what the situation is.

 

The idea is to remove the "surface charge" so as to get a truer voltage reading.

 

Definitely following this thread, as I think I am going to be coming up against a similar list of faults here shortly. Am also looking into ordering in a code reader to move forward. Good luck.

 

I've left the battery fully charged and connected in the car. My voltmeter read over 13 volts when I connected the battery and the code reader read between 12.5 and 12.6 when it tested it.

I'm left with 4 error codes on the scanner
P0113 Intake air temperature sensor 1 High bank 1
P00AD Intake air temperature sensor 1 circuit high bank 2
P0102 Mass or volume air flow sensor a circuit low
P010C Mass or volume air flow sensor B circuit low

On the dashboard I have a red triangle warning can not apply park brake. When checking it looks like the park brake is seized on as the rear pads are tight against the disc.
The other dashboard warning light is steering column locked.

I also put a new battery in the key fob.|

Im leaving the car connected to a trickle charger hoping that this will clear any battery issues.

 

The next phase is to start the car. If it starts, there maybe a further reset of codes. Or since the codes are pending, clear them, and start the car.

 

The car won't start. It must be because of the handbrake and steering lock fault.

I need to discover how to clear them to start the car

 

Hand brake has no effect on starting.
Steering lock fault... did I miss something earlier? Has the car been the victim of a break in event?
