I had switched out my car batteries from my two s types, but I have run into a problem with the 2003 A Type R. After reconnecting the battery, the headlights and dog lights stay on and take fob key isn't recognized. Even after inserting the key, it doesn't start take car after position 2. Any ideas? I have to take off the negative battery cable to keep the car headlights from draining the car battery.

 

Hopefully all of y'all understand my misspelled words. Such as fog lamps instead of dog lights as well as S Type R, instead of A Type R. Sorry for the confusion. I'm swiping on my cell phone. ��

 

If you changed it with key out of ignition it has to be something like a bad connection.

 

Its just weird that after changing out the battery, battery getting drained because the headlights do not turn off, then recharging the battery, and reinstalling the battery in the same ol thing happens again, that I am at my ends wit. I have to take the negativeI have off the battery so it doesn't drain the battery due to the head light staying on. I've read the manual on security but there's nothing about the lights starting on after an install in the security section.

 

You probably disturbed a wire - it's now loose, chafed, or whatever.

 

Anyone else have any ideas?

 

This is what I got so far with a Jag specialist...

I have a 2003 Jaguar S-Type R. I changed out the battery, then the issues began. The headlights and fog lights stay on. The alarm system activates after opening the door. I insert key and it doesn't start. The fob key isn't recognized.

Hello and welcome to justanswer.com

I recommend we first disconnect just the negative battery terminal cable for at least an hour. Then reconnect it and lock then unlock the driver door using the key in the driver door lock cylinder. This should reset the security system. Let me know.
12 July 2015 08:26
I had done that, but, the headlights still stay on. Also, even after inserting the key, the radio turns on, but will not start the car after position 2. The vehicle still doesn't recognize the fob key.

Will the shifter release from park with the ignition on and foot on the brake? Turn the ignition ON and look at the security light on the top of the dash. Tell me what it does.
12 July 2015 09:11
When the key is inserted and the brake is pressed, The P is illuminated, but if the brake is released, the P starts blinking. Also, the parking brake on the instrument panel is blinking faintly. The headlights and parking lights continue to illuminate even after locking and unlocking the vehicle.

Ok something must have gotten spiked when the battery was replaced. The lights is an indication of a power loss to the front module. I know you stated you checked fuses but we need to double check power to both sides of all the fuses in the engine compartment, trunk and passengers kick panel fuses. With the ignition on power should be present on both sides of each fuse. There are a couple that will not have power at all so let me know. Also check the inertia switch again just in case.
13 July 2015 08:06
I will be checking that this morning, but why would the headlights still be on? Throughout this whole process, the headlights, fog lights, and tail lights are on and can not be turned off.

If the front module loses a power signal then this can happen.
13 July 2015 02:58
I believe this is where a should focus because I don't see any fuses that are burned.

Ok look again at the security light. Turn the ignition ON and look at the red security led and tell me what it does.
13 July 2015 04:33
If you are talking about on the dash display, it doesn't do anything. There is faint blinking of brake and oil light. Information display says nothing.

The security light is a red led at the top center of the dash. Let me know what it does.
13 July 2015 04:49
It doesn't do anything. No red light on or blinking.

Not getting any light on the security light on the dash. I tried doing the same thumb with my 2001 Jaguar S-Type to get the same results, but the 2001 started right up after changing out the battery and resetting the security. I'm really perplexed on this issue. I don't want to take it to the Jag dealer tomorrow, can I get some other remedies to this external lights issue after reconnecting the battery?

Ok since the cluster is not even powering up normally it does sound like a voltage issue. This is why we need to check voltage with a meter to all fuses. Also look in the trunk for a two wire white connector that is not plugged into anything. Make sure this is not damaged like being trapped under the battery.
13 July 2015 08:51
I saw that wire, I moved it out of the way. My concern is, I have read back on another guy that had the same problem who had asked you about the exact same problem, but there was never a resolution.
13 July 2015 09:05
Richard Richard

I will stay with you for as long as we need. It really does sound like a voltage problem as the cluster should power up when we turn the ignition on. This is why I recommend checking voltage to all fuse boxes.
13 July 2015 09:09
You don't think that this could be a security issue that locks up the car to where it is inoperable and I'm forced to take it to the Jaguar Dealer Service leeches?
13 July 2015 09:12
Richard Richard
Jaguar Mechanic
No the security will prevent the vehicle from cranking but it will still power up and all accessories would work.
13 July 2015 09:18
The radio still works, the navigation works, but the air doesn't not will it start after position 2. What I can't understand is why the external lights are all powered on. I've never seen that. I'm having to disconnect the negative battery every time to keep it from draining. What would activate the lights after reconnecting the negative battery cable? The lights don't even power off after the security is bypassed. Am I going to have to check every fuse with a meter? I will have to buy one.
13 July 2015 09:19
What I meant to say was that the air doesn't work nor does it start after position 2, everything just goes dark.
13 July 2015 09:25

That is what I recommend. It really sounds like a voltage loss. If we are sure the battery is fully charged and the inertia switch is not tripped we need to check voltage with a digital meter. Please go over again the battery and cable connections.
13 July 2015 09:30
I'm to check every fuse as well as every relay? So engine compartment, passenger side fuse box, and trunk?
13 July 2015 09:43
Richard Richard
Jaguar Mechanic
By checking for power we would also check the relays. Yes all fuses that you can check in the trunk, engine compartment and kick panel.
13 July 2015 09:49
So, other than checking the fuses and relays, there just isn't an easy answer to why the external lights are not shutting off? I'm a bit scared on playing with electricity, especially when all the lights are on. Its eating up the battery, I won't get a good reading since all the juice is being consumed by the headlights, fog lights, and brake lights.
13 July 2015 09:54
Richard Richard

We should put a charger on the battery to keep the voltage steady.
14 July 2015 03:36
I've checked the fuses. No issues to any of the fuses.
14 July 2015 03:54
Richard Richard
Jaguar Mechanic
So all fuses have 12 volts on both sides. There should be fuses that will not have power unless that function is being used. Can you turn the ignition ON and send me a picture as to what the cluster looks like.
14 July 2015 04:12
The instrument cluster does not come on.

Ok this tells me the cluster is not getting power. PLease go back to the battery and go back over the cable connections. Then go back to these fuses in the primary fuse box in the passenger side kick panel to make sure we have good voltage to both sides. If all is good then we have a wiring harness problem. Fuse #4 (5 amp), #13 (5 amp) and #20 (10 amp. First do the test with the ignition off and tell me which ones have power. Then turn the ignition ON and tell me which ones have power.
16 July 2015 11:01
Im going to check on that today, but are you familiar with the the vehicle going into immobilizing mode to where there is nothing I can do other than flashing the ECM? We have to troubleshoot on why it doesn't recognize the fob key.
16 July 2015 11:31
Richard Richard

The remote is controlled by the driver door module hut the actual security system for starting is between the ECM and instrument cluster.

 

The most likely way I can see the action of changing the battery causing so many faults is that it was connected the wrong way round. Or, possibly it might do this bizarre stuff if the key was in the ignition when the battery was changed.

Beyond those, I don't see it being caused by the change.

I'd get the circuit diagram, remove fuses & relays that don't look essential, and see if it is OK. If not, I'd swap fuses & relays that are still there for others (to rule out any weird failures) and if still no success I'd take more out and go measuring volts. I'd also disconnect modules.

If I thought it might be the ignition I'd take it apart. Ditto the lights stalk.

JTIS has very detailed pinpoint tests and I suppose I'd follow them.

It will take a HUGE amount of time (and a logical approach) if not found fairly quickly.

 

I finally gave up and sent the 2003 R to European Vehicle Specialist a few days ago. Whats funny is that yesterday I had gotten a call to where they couldn't figure it out either. They've got one more day till I'm forced to swallow my pride and get it towed to a Jaguar Service center.

 

Brian, search user profiles for Motorcarman. Bob is in Boyd, major contributor on here awesome guy and former Jag Tech who works from his home shop. fantastic Tech. Worth towing to his place. reach out to him.

I have towed my jag 40 miles to his shop.

 

Do you have Bob's phone number?
Maybe you could PM Brian so he can contact him if he wishes.
It doesn't sound like there will be a simple fix.

 

That occurred to me too. Not sure how to confirm or fix.

 

Before I switched out the batteries I reconnected the original battery, which there was no way I could had reversed it since the battery was still in the same place and wasn't moved.

 

Trust me! I would rather tow it to someone than to the dealer! lol

 

So simply disconnected/reconnected the same battery in the same car then. Hmmm, got me there. Sorry.

 

So, I got a phone call today from the guys at the Euro Service location....they were dumbfounded and couldn't figure out what was wrong. Said that they couldn't get their computer to talk to the car. They said that they ruled out immobilizer because items were still working such as the radio. Uggg!! Now you know when a specialized location with Euro equipment couldn't figure it out...just like good ol Han Solo would say, "I have a bad feeling about this."

 

So, I took my car to the Jaguar Dealer, get a phone call stating that their computer cant communicate with the cluster....no duh! I already told them that! What I wanted them to do was to figure out why there is no communication with the cluster and why the circuit is still open on keeping all the exterior lights on when the battery is reconnected. If I end up getting a used instrument cluster and replacing it, could I test this theory or should I just let them put in a new cluster?

 

It's part of the immo etc so you can't just swap it. You risk anti-theft lockout.

Bad wiring is more likely than the cluster, judging by previous posts.

 

Lets say that the cluster is bad though, wouldn't I be able to test it with a used cluster to see if I can get the cluster to turn on? If the Jaguar technician says that they can't communicate with the cluster, that means they can't even flash it?

 

Is there an immobilizer on the STR? Would that cause no communication with the cluster?
