Question about 2006 Jaguar XJ8

Location of computer connection in 2006 XJ8L

After accidentally leaving the parking lights on overnight, my battery had lost a bit of its power, and when I started the car, the warning lights for "Apply foot and parking brake" came on with rapid beeping. I could live with the lights for a while but there is no way to turn off the beeping, which will drive you crazy. Since I am a long way from my Jaguar dealer, I went to the best Ford mechanic anywhere near and he said he'd be glad to turn the warnings off. Unfortunately he could not find the computer connection! Where is it, please???!

Hi.
Try disconnecting the battery for a few minutes ,to reset the computers memory, and reconnect.
I have had a few cars with this problem, and its the "gremlins" as I call them, giving you false signals, usually originating when battery is flat.
Good Luck.
John.

When Iturn on the key no lights came on


First, check your battery. Next, why is it dead? Did you leave your park lights on overnight? Is the battery too old?
If your battery is good, check the main fuse, usually very near the positive terminal on the battery, and check the battery connections - are they in good condition, are they nice and clean?

My keys lost their programms


Unlikely both keys have lost the programming.

Remove the car battery and give it a full charge, leave side light switch "on" while battery is removed to provide discharge path for the engine management system. Refit battery and try again.

My parking lights stay on when i turn the engine off of my 2006 ford explorer, i have to disconnect the battery to turn them off


Try unhooking one of the battery cables and leave it off for at least 20 minutes. When you hook it back up the computers should re-boot. That has solved problems for me with heater, interior lites, power windows, AC, day time running lites, power mirrors, fast idle, rough or slow shifting, CD player, and wipers on GM autos and S-10 PU and Dodge trucks. None of the switches are connected to the device they control anymore. The switch tells the computer to open the window and the computer send a signal to the window motor. When the computer gets confused strange things will happen or not happen. Of course you may have to re-set your radio stations.

if i'm not mistaken... i believe there is a disable switch located around the lock mechanism when you have the boot open... it might have accidentally gotten bumped

Security light stays on and occasionly something runs down battery overnight .since i lost my keys with remote opener these problems have come up. this car is a 1994 buick park ave ultra.


One of the door pin switches is faulty, Interior light must be staying on and draining the battery. If you don't see the dome light staying on possibly the trunk switch is bad.

Air bag light flashes 5 times then2 times how to reset light have tried leaving battery disconnected overnight to no avail.light started after removal of fuses to check for power to rear wipers.


CLEARING CODES (works for code 52)
1. Only intermittent codes and codes that diagnostic monitor recognizes as being repaired may be cleared from memory. To clear codes, cycle ignition OFF to ON. Observe AIR BAG warning light. AIR BAG warning light will illuminate for 4-8 seconds, and flash fault code.

(Comment) Loosely translated - If you dont have the problem fixed, this wont work. Code 52 should clear with this!

2. Locate air bag diagnostic 2-pin connector.

(Comment) This was a fun one. According to the air bag wiring diagram that I also got from Mitchell, the Airbag Diagnostic Connector is located "Right side of Instrument Panel". The only thing I found immediately to the right of the I/P (between the stereo and Instrument panel) was a black computer with 4 connectors which is NOT what I was looking for. I finally found a blog that mentioned the computer for the air bag computer was behind the right side kick panel. Sure enough....there it was. Attached to the side of the diagnostic computer was a two prong diagnostic connector.

3. Connect a jumper wire between diagnostic connector terminals. Leave jumper wire connected until diagnostic monitor tone sounds (about 5 seconds). Disconnect jumper wire. Fault code is cleared.
